Why I Left Mormonism and Became an Atheist, and What it Would take for me to Return to Religion


In this piece I discuss my five main reasons for leaving Mormonism: historical anachronisms in the Book of Mormon, the existence of many competing prophets and holy books, changes made to temple ordinances, the inaccuracy of Joseph Smith’s translation of the Book of Abraham, and the unreliability of subjective spiritual experiences as evidence. For each reason I include a reflection as to the general lesson I learned from this which I now apply in my examination of other religions. I conclude with some remarks about the important of seeking truth through reason and consideration of alternative views.


I was born into a Mormon family. Both my parents were Mormons, and for the first twenty years of my life we went to church (more or less) every Sunday. I regularly read the Book of Mormon and other scriptures, attended additional church activities, volunteered at church events, and on several occasions gave talks at different congregations. When I was nineteen years old I went overseas for nine months (shorter than the usual two years owing to health reasons), to share the teachings of my church full time in what Mormons call ‘serving a mission’.

Several months after returning home, I was preparing a church lesson that I was to present when in the course of my research I stumbled across some historical information about Joseph Smith and the Book of Mormon which was concerning to me and with which I had previously been unfamiliar. I cannot recall exactly what this first material was, but it marked the beginning of a period (from 19th December 2009 to 28th February 2010) of intense study, reflection, and prayer. After a great deal of reading and an immense quantity of soul-searching, I eventually came to the conclusion that I was most likely mistaken in my beliefs, and that Mormonism was probably not the true religion.

I told my parents of my decision on the morning of Sunday 28th February 2010, and as of that day I stopped going to church, and have never returned since. In the intervening five years, I have learnt much more about philosophy, history, and science, and grown a great deal as a person. Nevertheless, my outlook and views are still shaped to a significant degree by my time spent as a Mormon, and my experiences in leaving Mormonism.

In this piece, therefore, I explain my reasons why I changed my beliefs, and the lessons I believe that I learned from these reasons which affect how I evaluate religious and other claims to this day.

Book of Mormon Anachronisms

Key point: the Book of Mormon contains numerous references to animals, technologies, and languages which did not exist in pre-Columbian America.

Out of Place Animals and Artefacts

I was raised to believe, as do most Mormons, that the Book of Mormon is an ancient record of various peoples who lived on the American continent which Joseph Smith translated into English by the power of God. It was not always clear to me how the events it narrates intersected with secular history, but nonetheless I believed that the two would be reconcilable if we had sufficient information. When I began to read more concerning the historicity of the Book of Mormon, however, I discovered that many specific practices, animals, and objects that it refers to simply did not exist in Pre-Columbian America.

Among those things mentioned explicitly in the Book of Mormon for which (as far as I am aware) no evidence has been found in ancient American cultures, and which mainstream scholars and scientific institutions do not believe existed or were found in the ancient Americas, include:

  • Knowledge of Hebrew or other Semitic languages (Mosiah 1:2, Mormon 9:33)
  • Jewish religious sacrifices, priests, temples, etc, (Mosiah 6:3, Mosiah 2:3, 2 Ne. 5:15)
  • Jewish synagogues (Alma 16:13, Alma 32:1)
  • Record keeping on plates (Mosiah 8:5,9)
  • Horses or the wheel (3 Ne. 3:22, 3 Ne. 4:4, Alma 18:9-12, 1 Ne. 18:25, Enos 1:21, Alma 20:6, Ether 9:19)
  • Domesticated cattle (Enos 1:21, Mosiah 13:18, 3 Ne. 3:22, 3 Ne. 6:1, Ether 9:18)
  • Donkeys (Mosiah 12:5)
  • Steel (Jarom 1:8, 2 Ne. 5:15, Ether 7:9)
  • Advanced metallurgy, including smelting (Mosiah 21:27, Helamen 6:11, Ether 7:9, Ether 10:23, 2 Ne. 5:14)
  • Silk (1 Ne. 13:7, Alma 1:29, Alma 4:6, Ether 9:17, Ether 10:24)
  • A land northward covered with bones, rusted metal weapons, bronze and copper breastplates, many ruined buildings, and more written records (Mosiah 8:8-10)
  • A tradition or mythology of being cast out of an ancient land and travelling across the sea (Mosiah 10:12)
  • Metal coinage (Alma 11:5-19)

Apologetic Responses

Learning about all these discrepancies was greatly disturbing to me. Like many Mormons, I was ignorant about the history and archaeology of the ancient Americas, and was not aware that the sorts of artefacts that the Book of Mormon predicated should exist simply had never been found. I went to the Mormon apologetics websites to see what responses existed, thinking there was presumably some explanation for such apparent discrepancies. The responses that I found seemed to fall into three main categories:

  • Appeals to some obscure finding of a possible horse fossil or piece of steel, etc, which were advanced by various Mormon apologist scholars but did not seem to be accepted by any other academics.
  • Claims that the Lehites, Jarodites, and Mulekites (the three separate groups of people the Book of Mormon mentions having travelled to the Americas from the Old World) were only some of the peoples present in the ancient Americas, and thus we fail to find remains of their language, buildings, or material culture because there constituted only a fairly small proportion of the overall population.
  • By far the most common response, however, is that when Joseph Smith used words like ‘horse’, ‘steel’, and ‘silk’, he was not referring to horses, steel, and silk as we would understand them, but rather was using these words as translations for words which originally referred to something that looked somewhat like, or functioned somewhat like, horses, steel, silk, etc. Thus, the translation is not literal, but analogical. Horse does not refer to Equus ferus caballus, but instead to llamas or deer or some other animal, and is only rendered as horse for ease of narration and understanding.

My Reaction to the Responses

I thought about these responses, read some rebuttals to them written by others, and eventually came to the following conclusions:

  • Obscure findings not accepted by mainstream scholars and scientists might be legitimate, but it is unlikely. The fact that mainstream scholarship does not support the historicity of the Book of Mormon in the way that it does for much of the Bible (at least post-Exodus) counts as evidence against it being a historical record, even if it is not totally decisive evidence.
  • Other peoples may have existed in the Americas at the time or after the time of the Book of Mormon (though this is not a belief that seems to be widespread in ‘Mormon culture’, where generally it seems to be believed that Native Americas are descended from Lehites and Mulekites), however the cities spoken of in the Book of Mormon are large enough and the cultures advanced enough that we should expect to see at least some surviving remains and records.
  • The explanation about ‘alternate translations’ was the one I found least compelling. First of all, this is something virtually no Mormons I knew believed or spoke about – certainly I was always brought up to believe that in the Book of Mormon, horse meant horse, steel meant steel, etc. Secondly, many of the items referred to simply have no known plausible alternate referent: there are no pre-Columbian domesticated animals that were anything like horses or cattle or sheep. Bison (one proposed candidate for ‘cattle’), were never domesticated, and deer (a proposed candidate for ‘horses’) are not ridden or used to pull chariots. Another suggestion is that ‘horses’ refers to ‘llamas’, but horses and llamas are really nothing like each other, and llamas are not used to pull chariots. Likewise, there was no smelted metal that was used at the time in ancient America which could plausibly be described as ‘steel’. Thirdly, the notion that ‘horses’ and ‘cattle’ are loose translations of some other form of animal seems inconsistent with the fact that some names in the Book of Mormon are left untranslated, including the unknown metal ziff (Mosiah 11:8), and the animals ‘cureloms and cumoms’ (Ether 9:19). It seems implausible that Joseph Smith would choose to, or be instructed to, use misleading translations like ‘horse’ and ‘steel’ whilst at the same time leaving some names untranslated. If ‘steel’ is actually some other metal or material, why not leave that untranslated? Of why not just call ziff ‘steel’? This inconsistently seems to have no explanation if Joseph was indeed receiving divine revelation during his translation.

Problems with Dating the Birth of Christ

There is one further problem with the historical accuracy with the Book of Mormon which, as far as I know, I may be the first to have noticed (I’m sure other people have come across this too, but I can’t recall having read of it anywhere else). The problem concerns that dating of the birth of Christ. 1 Nephi 1:4 states clearly that the record begins at the beginning of the first year of the reign of Zedekiah, which has been dated to 597 BC. In 3 Nephi 1 versus 1,4, and 26, it is made clear that the signs associated with the birth of Christ occurred exactly 601 years after Lehi left Jerusalem. So, if Lehi left Jerusalem in 597 BC and Christ was born 601 years afterwards, that places Christ’s birth in the year AD 5 (remembering there was no year 0). This date is simply far too late; even the traditional dating places Christ’s birth at 1 BC, and most modern scholars accept a date of 4 BC or earlier, given that Herod died in this year and so was not alive in 1 BC.

Thus, according to the Book of Mormon, Jesus was born about nine years after he actually was. I do not think it is plausible to argue that the dates given are approximate, as says quite clearly ‘the ninety and second year of the reign of the judges’. This also tallies with Mosiah 29:46, which tells us that the first year of the reign of the judges (when Mosiah died) occurred 509 years after Lehi left Jerusalem, and 509 plus ninety-two equals 601. Joseph Smith was generally quite good with keeping dates in the Book of Mormon internally consistent, but in the one instance where we have the ability to cross-reference them with known historical events we find a discrepancy. A nine year discrepancy in dates is hardly sufficient by itself to totally discredit the Book of Mormon, but to me it was interesting (as I discovered it myself as far as I know) counterevidence to the belief that the book was divinely inspired, especially given that Joseph Smith declared the Book of Mormon to be “the most correct of any Book on earth”.

Lesson 1: Historicity matters

The lesson that I take away from this examination of the historicity of the Book of Mormon is that it is exceptionally important to examine religious events that claim to be historical, and determine whether their claims are consistent with what is known from history and archaeology. Any inconsistencies that are uncovered do not by themselves necessarily disprove the religious claim, since history and archaeology can be wrong. Inconsistencies of this sort do, I think, count as evidence against the claims, and the greater are the discrepancies, the less plausible it becomes that the religious events in question actually took place.

Before accepting a new religion, therefore, I would need to conduct a careful investigation of whatever historical claims it makes, and determine the extent to which they are validated by, or at the very least consistent with, what we otherwise know about history. This is one reason why, for instance, I have become very interested in the historicity of the New Testament, and am concerned by some of its potential inconsistencies and problems (particularly the birth narratives). I am now very wary of religions that make false claims about history.

Competing Prophets and Holy Books

Key point: there are numerous prophets and holy men who have produced their own works of scripture comparable in various ways to the Book of Mormon, and there is no clear basis for accepting the claims of one over the other.

Other Claimed Prophets and their Scriptures

One of the most common reasons for accepting the Book of Mormon as divinely inspired that I heard as a Mormon was that there is no possibility that an uneducated young man like Joseph Smith could have written the Book of Mormon by himself, given its considerable length, narrative complexity, internal consistency, inclusion of many specific cultural and technical details, and application of various literary conventions. I myself found this argument quite compelling for quite some time. During the course of my research, however, I discovered that there have been a great many alleged ‘prophets’ who, like Joseph Smith, have written lengthy and intricate works which they claim to have been revelations or divinely-inspired translations of ancient records.

A brief selection of some of these, many of them being breakaways from the main body of the Mormon church, includes: James Strang who wrote The Book of the Law of the Lord, Goker Harim who wrote The Sealed Portion of the Brother of Jared, Christopher Marc Nemelka who wrote The Sealed Portion: The Final Testament of Jesus Christ, Art Bulla who wrote The Revelations of Jesus Christ, and Joseph Morris who wrote The Spirit Prevails. Particularly intriguing is the case of Pearl Lenore Curran, an alleged spirit medium around the turn of the 20th century who produced a voluminous amount of literature (including many poems) allegedly all authored by the spirit she was in contact with.

View of the Hebrews

I also found out about a very interesting work called View of the Hebrews, which was published seven years before the Book of Mormon by New England clergyman Ethan Smith. It shares with the Book of Mormon a number of key themes, including that native Americans are descended from Israel, and the inclusion of many references to Old Testament prophets. There is no evidence of which I am aware that Joseph Smith knew of this book or copied it in any direct way, and there are many differences of details between the Book of Mormon and View of the Hebrews.

I do believe, however, that the existence of this work does show that many of the core ideas and major themes of the Book of Mormon were already circulating in the intellectual and social spheres in which Smith was raised. This does not prove that the Book of Mormon is not divinely inspired, but it seems to me more consistent with the hypothesis that Joseph Smith wrote the book out of his own (very vivid) imagination drawing upon ideas that were current at the time, than with the hypothesis that the content of the book was revealed de novo from a divine source.

Could Joseph Smith have written the Book of Mormon?

Another claim with which I was familiar was that the time taken to translate the Book of Mormon was far too short for it to have been done without divine inspiration. During the course of my research I began to have doubts about this claim, and at one point I sat down to do the math. The bulk of the Book of Mormon was dictated by Joseph Smith during a single period of 90 days, some sources saying that only about 65 of these days having been used for translation work. The Book of Mormon is 275,000 words long (which includes quite a lot of material copied verbatim from Isaiah which should probably be excluded from this count). If we assume Smith worked 65 days, he must have produced an average of 4,200 words per day, which for an eight hour day is roughly 530 words per hour, or about nine words per minute. Putting it that way, the output seemed much less miraculous to me. Still quite impressive to be sure (Smith was known to be a keen story teller and have a very active imagination), but hardly superhuman.

It must also be remembered that Smith originally started writing over a year before, when he produced the 116 pages that were subsequently lost. Thus Smith had quite a lot of time to think about, and perhaps even make notes, concerning his story – it’s certainly not the case that he started from scratch at the beginning of those 90 days. Also, Joseph Smith had a further eight months to make corrections and adjustments before the book was first published in 1830. Even then, the first edition is not the polished work we read now: it was not broken up into versus, and the chapter divisions were much longer and different to those now used. There were also a large number of spelling and grammatical errors which were progressively corrected by the church in subsequent editions. Considering all these factors, I came to conclude that although the production of the work by Joseph Smith was quite impressive, it was not a superhuman feat, and can certainly be explained without appeals to divine revelation.

Lesson 2: Comparative religion matters

The primary lesson I have taken away from this analysis of different prophetic works is the importance of not considering the merits of only a single perspective, but to instead compare the relative merits of different religious teachings. Joseph Smith’s claims and writings looked far more impressive to me when they were all I knew about, and much less impressive after I compared them alongside the alleged prophecies and holy books produced by many other religious leaders. It is so easy for one viewpoint to look amazingly compelling when it is the only one we have seriously examined.

This observation has contributed to my current deep concern with religious disagreement, and desire to find some clear, objective criteria on which the truth or falsity of given religious claims can be adjudicated. The mere fact that a religious book and body of thought seems incredibly impressive and compelling to us is insufficient, when there are so many in other traditions who think that their revelations, their beliefs, and their holy books are likewise so uniquely compelling. We need to try to look at things from comparatively form multiple perspectives, and not merely from within the narrow framework of the one tradition we are comfortable and familiar with.

Changes to Temple Ordinances

Key point: certain Mormon temple ordinances have undergone significant changes since they were originally restored by Joseph Smith, contrary to the church’s own teachings that God’s ordinances cannot be altered.

A Note to Mormon Readers

In this section I do not discuss or reveal any details or aspects of the current endowment ceremony which endowed members have covenanted to keep sacred. I limit myself to general remarks, and go into details only in the case of certain elements of the ceremony that have now been removed. If even this makes you uncomfortable, skip this section.

Changes to the Endowment

All Mormons go to religious services at a chapel each Sunday, but those who are of age and deemed worthy are also encouraged to attend another set of worship services in a building called the temple. There, Mormons perform special ceremonies and ordinances, the most important of which is called the ‘endowment’. Most members experience the endowment ceremony as a combination of pre-recorded videos and live actions performed by those present. With a few small exceptions, the entirety of the ceremony, which lasts over an hour, is scripted, and thus is performed word-for-word identically on every occasion. This is relevant because this script has been changed in some important ways since the endowment was introduced. Aspects of the endowment which have been significantly altered include the following:

  • Penalties: the endowment used to contain penalties associated with revealing any of the sacred elements of the ceremony. These were removed in a 1990 revision of the ceremony.
  • Ministers as agents of Satan: the ceremony contained several scenes in which a protestant minister was portrayed as an agent of Satan. This was removed in the 1990 revision.
  • Wives obedience to husbands: women used to be required to promise to ‘observe and keep the law of your husbands, and abide by his counsel in righteousness’. In 1990 this was changed to ‘obey the Law of the Lord, and to hearken unto the counsel of her husband, as her husband hearkens unto the counsel of the Father’.
  • Oath of vengeance: beginning in the days of Brigham Young and lasting until around 1930, the endowment ceremony included an oath of vengeance for the murder of Joseph and Hyrum Smith. It read ‘you and each of you do covenant and promise that you will pray and never cease to pray to Almighty God to avenge the blood of the prophets upon this nation, and that you will teach the same to your children and to your children’s children unto the third and fourth generation’.
  • There have also been substantial changes to another ordinance called the initiatory. For more information on this see http://www.i4m.com/think/temples/temple_ordinance.htm

There is no question about these changes; they are not lies made up to discredit the church, as some Mormons tend to say of such things. More information can be found on the relevant wikipedia pages, and also on the FairMormon Mormon apologetics website.

Divine Ordinances Cannot be Changed

While Mormons and non-Mormons alike may be troubled by the content of these removed portions of the endowment, most troubling of all for me when I discovered this information was that it seemed to directly contradict the church’s teaching that God’s ordinances must be performed exactly in the specified manner and cannot be altered. This was one of the justifications of the need for a restored church in the first place, namely the argument that the original correct form of many ordinances like baptism had been lost and corrupted over time. As stated in the official church publication Teachings of the Presidents of the Church:

“Ordinances instituted in the heavens before the foundation of the world, in the priesthood, for the salvation of men, are not to be altered or changed.”

Likewise from the church magazine the Ensign:

“Through time and apostasy following Christ’s Resurrection and Ascension, however, the divine authority of the priesthood and the sacred ordinances were changed or lost, and the associated covenants were broken. The Lord revealed His displeasure over this situation in these words:“For they have strayed from mine ordinances, and have broken mine everlasting covenant;”

And from church General Conference:

“We explained briefly the Apostasy and the Restoration: that there is vast evidence and history of an apostasy from the doctrine taught by Jesus and his Apostles, that the organization of the original Church became corrupted, and sacred ordinances were changed to suit the convenience of men, and that today good people all over the world are confused with contending religions with differing doctrine and methods of worship.”

Apologetic Responses

Mormon apologists have claimed that there is a difference between changing the ordinances themselves, and changing some outward details of their presentation. This is certainly contrary to what I was always taught, that God’s ordinances must be performed exactly. It also seems contrary to teachings such as this:

“No jot, iota, or tittle of the temple rites is otherwise than uplifting and sanctifying. In every detail the endowment ceremony contributes to covenants of morality of life, consecration of person to high ideals, devotion to truth, patriotism to nation, and allegiance to God.”

According to this passage, every small detail of ordinances is important. Changes as substantial as removing entire portions of the endowment would thus surely be counted as ‘important’ details which contribute to the spiritual value of the ordinance, and thus presumably ought not to be changed. The church does not like to discuss these matters, and discourages members from speaking too openly about temple ordinances, even beyond the specific aspects that members promise not to reveal. As such, relatively few members (especially younger members) are aware of these facts. When I became aware of such things, my confidence in the church, though not completely undermined, was considerably shaken.

Lesson 3: Openness is essential

The main lesson I gained from learning about the changes to temple ordinances was the importance of openness to critical examination and discussion. The LDS church is notoriously sensitive to criticism, and very secretive about matters such as changes to the temple ordinances. I am not talking here about keeping certain aspects of the ordinances sacred; I’m talking about hiding from members the changes that have been made to key salvific ordinances (this also applies to various aspects of church history, but that’s another matter).

I do not believe that truth needs protecting, and were I to adopt another religion I would look for one which is open about its past and present activities, and which does not attempt to keep certain facts from its members or discourage them from thinking critically about such things. Any sign of resistance to critical open enquiry of this sort is thus very suspicious and off-putting to me. No true religion should feel the need to ‘protect’ its members from facts that they think may be unpleasant or may lead them to doubt.

Inaccurate Translation of the Book of Abraham

Key point: Joseph Smith claimed to translate the Book of Abraham from ancient Egyptian papyri. Some of these papyri have been discovered, and the translations provided by modern Egyptologists bear no resemblance to those given by Smith.

Background to the Book of Abraham

The Book of Mormon was not the only ancient record Joseph Smith claimed to have translated. In 1835, Joseph Smith acquired several ancient Egyptian papyri taken from some mummies that had been brought to America from Egypt several years earlier. At the time, Egyptian hieroglyphics had still not been deciphered, and owing to his famed translation abilities Smith was asked to attempt a translation. Smith examined the papyri and declared that they contained the writings of the ancient patriarch Abraham. He translated the papyri over the course of a few months, and the resulting work, the Book of Abraham, was published several years later and eventually canonised by the church in 1880. It now forms a key component of the Pearl of Great Price, one of the four canonical texts of the church.

Joseph Smith’s Inaccurate Translations

The original papyri owned by Joseph Smith were long thought to have been lost, but in 1966 several fragments were discovered in some university archives. It is unclear exactly what proportion of the original documents these fragments represent, however they do include large portions of one of the figures (called facsimiles) that are included in the Book of Abraham alongside the text (see here). Numerous professional Egyptologists have since examined these recovered fragments, and they are uniform in their assessment that their content bears no relation whatever to Smith’s translation. Essentially, the papyri are first century Egyptian funerary texts, and contain no mention of Abraham or any of the other doctrinal or historical elements contained in the Book of Abraham.

Apologetic Responses

When first I discovered these facts I was shocked and dismayed. This seemed to be a very clear disconfirmation of Joseph Smith’s ability to translate through divine assistance. I immediately sought out responses of Mormon apologists to see what they had to say on the matter. In preparing the present article, I discovered that just last year the church published a piece on its website discussing the translation of the Book of Abraham. The answers provided in this piece fall into two basic categories, and are essentially the same as those I read on Mormon apologetic sites when conducting my original research:

  • Since we have only recovered a fraction of the original papyri, we do not know whether the portions we have are the same as those Joseph Smith translated from, or what degree of overlap there may or may not be.
  • Joseph Smith may not necessarily have engaged in a literal textual translation of the papyri. I will quote from the lds.org essay on the subject, which articles this perspective quite succinctly: “Joseph’s study of the papyri may have led to a revelation about key events and teachings in the life of Abraham, much as he had earlier received a revelation about the life of Moses while studying the Bible. This view assumes a broader definition of the words translator and According to this view, Joseph’s translation was not a literal rendering of the papyri as a conventional translation would be. Rather, the physical artefacts provided an occasion for meditation, reflection, and revelation. They catalysed a process whereby God gave to Joseph Smith a revelation about the life of Abraham, even if that revelation did not directly correlate to the characters on the papyri”

My Reaction to the Responses

I never considered these responses to be very satisfactory. At the very least, we know that Joseph Smith did not translate facsimile 1 correctly, since we have recovered large portions of it, and if any inference can be made about the missing portions of the papyri, surely the most reasonable presumption would be that they would likely resemble in subject matter the portions that we do have, not that they would concern matters totally unrelated. As to the idea of a ‘non-literal translation’, once again this is not what I had always been taught. I was always told and read in church materials that the Book of Abraham, like the Book of Mormon, was a genuine translation of a real historical document.

There is no way we can know from historical investigation whether or not Joseph Smith received some sort of spiritual revelation catalysed by the papyri, however from my perspective the evidence fits far better with Joseph Smith having falsely believed in his divinely-inspired ability to translate, rather than God actually having inspired Joseph to write something that bore no relation to the document he thought he was translating, and then have highly misleading teachings about said document continuing to be taught throughout God’s true church. Like everything else, this alone is not completely definitive, but for me it was exceptionally compelling counterevidence against Joseph being a true prophet of God.

Lesson 4: Beliefs need to be testable

From my investigations of the Book of Abraham, and particularly upon discovering the ‘not a literal translation’ response, it became increasingly clear to me just how important it is that we have same method of testing or falsifying our beliefs. Not in some scientistic sense, but simply in the sense of being able to determine whether they are likely to be true or not. The ‘spiritual translation’ answer was so unsatisfactory to me precisely because there is no way to tell whether it is true or not, and can therefore be said of essentially any text from any religion. Thus, any religion which I joined now would to have at least some methods of testing out the truth of its claims, and not merely rely on completely untestable claims of spiritual revelation.

The Unreliability of Subjective Spiritual Evidence

Key point: Mormon doctrine places very heavy emphasis on personal spiritual witness as the prime method of learning the truth of the church, however the existence of many competing religion, as well as the findings of modern psychology, show that evidence of this sort is extremely unreliable.

Spiritual Witness in Mormonism

By far the single biggest reason why I accepted the truth of the Book of Mormon and the restored church is because of the validating ‘spiritual witness’ I believe I had received from God. Mormons believe this is by far the most important and most fundamental way one comes to a knowledge of the truth of the church, often appealing to a passage found in the Book of Mormon in Moroni 10:4, which reads:

“And when ye shall receive these things, I would exhort you that ye would ask God, the Eternal Father, in the name of Christ, if these things are not true; and if ye shall ask with a sincere heart, with real intent, having faith in Christ, he will manifest the truth of it unto you, by the power of the Holy Ghost.”

Mormons and those investigating Mormonism are encouraged to read the Book of Mormon and pray sincerely to God to provide them with a spiritual witness of its truth. For many years, I believed that I had received such a witness, which I described as a powerful sensation of peace, comfort, and insight that I gained when reading and pondering the Book of Mormon. I believed that this was a witness from God telling me that the things I was reading and praying about were indeed true, that they were good, and that they were from God.

Cognitive Biases and Conflicting Experiences

During my period of reflection, however, I started to learn about human psychology. I found out about expectation bias (how our expectations enormously shape our perceptions), cognitive dissonance (how we use motivated reasoning to manage apparently conflicting beliefs), the availability heuristic (our tendency to misjudge the probability of events based on a few particularly vivid examples), post-purchase rationalization, pareidolia (seeing patters where none exist), and selection bias (distorting our view of something by the biased way in which examples are chosen). I learnt about a fascinating book called When Prophecy Fails, which documents how may end of the world cults continue to believe even after their predictions fail to come to. I learnt about the immense research documenting the fallibility of human memory, how every time we recall an event we reconstruct and potentially alter the memory, and how relatively easy it is to generate false memories.

Learning about these things, I began to see how they applied in so many ways to my own experience as a Mormon, and also to the way in which Mormons approach spiritual witnesses generally. When I prayed for spiritual confirmation, it was with a strong expectation that I would receive it, which greatly increased the chances that I would come to believe I had such an experience regardless of whether or not there was any true supernatural involvement. Pareidolia would help ensure that I interpreted a wide range of potential thoughts, feelings, and sensations as being consistent with a spiritual witness. The immense amount of time and energy I had put into the church throughout my life would lead to a significant amount of cognitive dissonance and post-purchase rationalisation effects if I were to fail to receive a witness, and thus I was much more likely to convince myself that I had received one. My memory of the spiritual experiences I had had, and those I had heard about from others, was likely altered over time and perhaps had changed significantly from the way events originally occurred.

I also became increasingly concerned about the variability of personal spiritual witnesses across different religions. I found examples of people from Islam, Catholicism, Buddhism, and Wicca, all who reported experiences and feelings which were broadly similar in form to those I had experienced, and those I had heard other Mormons witness about. I wondered how different people could receive genuine spiritual witnesses of conflicting spiritual truths. The more I thought about this, the more dissatisfied I became with simply believing that I was right and others were wrong. I could not find any rational basis for thinking my spiritual witness, or those of Mormons I knew, where more likely to be true than those experienced by people in other religions. This realisation, combined with my new knowledge of human psychology and our powers for self-deception, eventually led me to believe that the experiences and sensations I believe I had had were in fact the products of my own mind, and not the result of divine influence.

The Three and Eight Witnesses

It was a result of similar considerations that I came to believe that the testimonies of the three and the eight witnesses (groups of men who claimed to have seen the gold plates from which the book of Mormon was supposedly translated) were also not a reliable source of information. In the course of my research on the matter I came across this quote by Illinois governor Thomas Ford, who opined that the event of the witnessing of the plates may have proceeding something like this:

“The witnesses were ‘set to continual prayer and other spiritual exercises.’ Then at last ‘he (Joseph Smith) assembled them in a room, and produced a box, which he said contained the precious treasure. The lid was opened; the witnesses peeped into it, but making no discovery, for the box was empty, they said, “Brother Joseph, we do not see the plates.’ The prophet answered them, ‘O ye of little faith! how long will God bear with this wicked and perverse generation? Down on your knees, brethren,  every one of you, and pray God for the forgiveness of your sins ‘ The disciples dropped to their knees, and began to pray in the fervency of their spirit, supplicating God for more than two hours with fanatical earnestness; at the end of which time, looking again into the box, they were now persuaded that they saw the plates.”

I had no reason to believe that the details of this hypothetical account are correct, but it seemed to me that something like this was eminently plausible given what I now knew about human psychology. There were also some other problems with the witnesses which came to my attention, such that virtually all of them were either relatives or friends of Smith, and a number of whom had strong financial and social interests in the success of the church. Also, the witnesses did not give their own independent accounts of events, but merely signed a single document prepared for them, thus leaving us with no way to corroborate their separate accounts with each other, or see whether each of them experienced the same thing, rather than each having their own rather unique spiritual experience which they then misremembered and reconstructed upon later recall as being consistent with the written account. I also found out that a number of other prophets had their own groups of witnesses, including Solomon Spalding and Jesse Strang. I found out about the many sightings of the Virgin Mary, some of them very well documented and with a large number of witnesses (as a Mormon I did not believe in such apparitions). All in all, I was left far less impressed with the accounts of the witnesses than I had previously been.

Lack of Apologetic Responses

Searching for responses to these concerns from Mormon apologists, I could find almost nothing. It was almost as if Mormons had never even thought about such questions before, a notion which I found both bizzare and deeply discouraging. In the face of such evidence and in the absence of any real responses, I became extremely skeptical both of my own spiritual experiences, and of the reported and recollected experiences of others. I no longer considered them to be a reliable way of finding truth, or of determining the veracity of writings like the Book of Mormon.

Lesson 5: Subjective evidence is unreliable

My experience with Mormonism has taught me to be highly skeptical of any claims to divine or spiritual knowledge gained primarily on the basis of personal religious experience, sensations, or feelings. I do not believe that such things are a reliable way of finding truth, and as such any religion which I joined today, though it may have an important place for such experiences, would not elevate them to be the primary means of determining the truth of religious claims.

Bringing Things Together

Leaving Mormonism

By the end of my period of intensive study and reflection, I had come to the conclusion that Joseph Smith was probably not a divinely inspired prophet, and that the church he established was probably not God’s true church. I did not come to this conclusion on the basis of any single argument or piece of evidence, but as a result of multiple, largely separate considerations, the five major ones I have outlined here (there were many other lesser considerations as well, but I have omitted them to save space). No single discovery I made was enough to completely undermine my faith by itself, nor did any of them definitively and conclusively disprove the truth of Mormonism. Rather, it was a question of relative plausibility and explanatory power of different ways of interpreting the facts.

Becoming an Atheist

Having come to the conclusion that Mormonism was probably not a true religion, I found myself having little or no reason to continue believing in god. The main reasons why I had previously believed in God were as a result of my belief in the Book of Mormon, in the first vision of Joseph Smith, and also as a result of my own personal spiritual experiences. Having become convinced that all of these reasons for belief were mistaken or inadequate, I lacked any reason to continue believing in God. I thus began describing myself as an atheist or an agnostic, depending on the mood I was in – at present I prefer the term ‘weak atheist’.

Continued Searching

To this day I remain open to the possibility that my decision to leave Mormonism might have been incorrect, and that the Mormon church is in fact true, and that Joseph Smith is in fact a true prophet of God. For me to once again believe in this, however, I would need to find compelling answers to these five problems I have outlined here, as well as a number of other comparatively minor matters that I have not discussed here. To my continued disappointment, none of my Mormon friends or acquaintances were interested at the time, or have seemed interested since, to discuss these issues and concerns with me.

Since leaving Mormonism I have also continued to search for new reasons or arguments as to why I should believe in God, or adopt some religion other than Mormonism. As yet, I have not found reasons or arguments which I find sufficiently persuasive. Nonetheless, my ignorance and limitations remain immense, and so the search goes ever on. I am still only near the beginning of my journey

Lesson 6: We must compare worldviews holistically

Partly as a result of my experiences investigating various aspects of Mormonism, I have come to the view that it is essential to consider a body of evidence collectively, rather than merely examining each argument or fact in isolation. It is certainly important to look at details of each particular argument, but if this is all one does, it is very easy to get caught in the trap of ‘explaining away’ every possible counterargument or discrepancy within the framework of what we already believe. In this way, we never shift our beliefs, and we are not receptive to new evidence.

Instead, we need to make the effort to consciously take a step back and think ‘which perspective, which worldview is most consistent with the evidence as a whole? What is the most reasonable thing to believe that has the greatest chance of being true?’ This means making a genuine sincere effort to understand alternate viewpoints and interpretations, rather than just dismissing them point by point on each particular argument. We need to put on the goggles of those we disagree with, see through their eyes, and then switch back to our own goggles and consider which pair provided the better view of reality. This is not an easy thing to do, but I think that if we wish to maximise our changes of holding true beliefs, it is something we must regularly strive for.

Some Concluding Thoughts on Reason and Belief

Many Christians I know are very committed to their faith, believing very strongly in Jesus and his power in their lives. Nevertheless, I have found that many such persons are unable to answer many of my questions, objections, and criticisms. When I raise such matter, they tend to change the subject, fail to get back to me after saying they will, respond in ways that seem to portray an almost complete lack of understanding of my perspective, or sometimes even flat out say to me that they do not know how to respond. At the same time, such persons, seemingly without fail (although I guess I cannot know for sure) remain unwavering in their beliefs. Nothing I say seems to have much of any impact at all. Even in the very act of being unable to provide any cogent or relevant response to something I have said, they nevertheless maintain the same level of confident certainty that their beliefs are correct. I speak mostly of my Christian friends here (and some of them are among my very dearest friends), though I suspect similar remarks would apply to many of my Mormon friends as well, had I ever had any substantive conversations with them about such matters.

My reaction to this attitude is one of considerable incredulity. It’s not that I want to prove to these people that they are wrong or to get them to change their minds. Rather, it’s a matter of wanting to understand their reasons, and becoming frustrated and disappointed when they seem unable to articulate them. As far as I can see, weighing up and interpreting evidence and arguments is the way we try to distinguish truth from falsity. If we hold on tenaciously to a belief even in the face of objections to central aspects of that belief to which we have little or no idea how to respond, then we are in effect abdicating our role as searchers after truth. If we are right, we hope to be so by sheer luck, not because we have done all we can to cleave true from false beliefs and maximise our chances of holding to the true and rejecting the false.

I refuse to believe that God created us with an intellect only to have us forego its use, and instead wallow in confident certainty in the very face of our own admission (tacit or explicit) that we do not have the tools we need to discern whether our most dearly held beliefs are in fact likely to be true. This is a rejection of the paramount importance of truth, an abdication of our intellectual integrity, and, having given up truth as our guiding light, constitutes a surrender to the vicissitudes of chance and passion to control our destinies. Such a life is not the life I want to live, and I call upon everyone everywhere reject this form of passive slavery to falsity and unreason, and instead fight with all our might, with all our strength, and with all our souls, to find out what is true, and to live by those truths that we find, always with a confidence proportionate to the reasons we have for belief.

This does not mean that we will have all the answers – that would be absurd – but it does mean that we should always have sufficient answers to justify our current level of confidence in how we can know what we claim to know. If we cannot give such answers but nonetheless hold fast to our beliefs, then we are lying to ourselves, and (if he exists) we are lying to God too, for we are pretending to know things that we do not in fact know, or at least do not know with the level of confidence we claim. I am guilty of doing this; I think we all are at times. But that doesn’t make it right or good.

I urge all people everywhere to think more carefully, to learn more, to listen to alternate views, and generally to put more effort into finding and holding onto truth, and not merely the appearance or the feeling of truth. I have no interest in this counterfeit version – only the genuine article will satisfy. I hope that Christians, Mormons, Atheists, and everyone else will recognise their fundamental underlying unity as seekers of truth, and join together on this grand and noble quest to understand this vast and confusing world in which we all live.

  2. As someone who left Mormonism due to the inherently sexist outlook on how it taught me to live my life, it’s nice to be able to see someone who has the good sense to question what they’re taught instead of simply accepting the ‘it just is’ response you get from so many members of the bishopric.


  3. I understand completely the position of the writer. Having been a convert to Mormonism, staying in it for 20 years, having served a mission for two years and then a stake mission, I finally asked to be excommunicated once I could not sustain the president of the Church as Prophet, Seer and Revelator and other theological positions of the Church. The Church uses the fact that its President is a Prophet and therefore doctrines/rituals, etc. can be changed. However, it seems that the changes always occur in very opportune moments related to the moods of society (ending of poligamy, prohibition of priesthood to blacks and eventually banning of such prohibition, changes in the endowment ceremony are some examples).
    Once out of Mormonism I continue to believe in a god and have been active in another faith for 30 years, eventually recently conceding that I just kept myself living in an illusion, and that any rational sincerely looking within oneself cannot but reach the conclusion that there is no god(s).
