In this article I outline the general framework of my overarching approach to the question of whether I should become a Christian. Beginning with William James’ observations that the decision regarding whether to adopt Christianity is both momentous and forced, I acknowledge that Christianity is not merely an intellectual exercise nor necessarily something we decide upon purely by our own volition. Nonetheless I conclude that the question of whether Christianity is in fact true is still paramount, and proceed to examine how one might go about determining the answer to this question. In doing so, I discuss the need to consider arguments for relative plausibility rather than certainty, and outline my view about the importance of basing our beliefs on reasons and evidences that are reliably truth-tracking. I then apply this framework to four major types of arguments advanced in support of Christianity: philosophical arguments for God’s existence, arguments based on the bible, experiential evidences, and the historical evidence for the resurrection of Jesus, in each case discussing how compelling I find the arguments, and why I ultimately find them to be insufficient. I then briefly consider three arguments which I believe mitigate against the truth of Christianity, namely the problem of evil, religious confusion, and evils done in the name of Christianity. I conclude with some reflections on the importance of the question and a plea for more sustained dialogue.
Background and Methodology
Momentous and Forced Options
Most fundamentally, the question I seek to answer is not ‘is Christianity true?’ More important to me is the even broader question ‘should I live as a Christian?’ The second question is related to the first, but the two are not synonymous. In particular, the question as to how one should live one’s life is much deeper and richer than merely a question concerning what is true. It depends not only on questions of facts about existence, but also on one’s values and on a certain element of personal choice as to what one wishes to commit oneself to. It also depends upon the set of plausible alternative life paths that are available, and their relative strengths and weaknesses.
To take a fairly trivial example just to illustrate the point, if Buddhism is true (read ‘the claims made by Buddhism about suffering, reincarnation, nirvana, etc’) and I don’t become a Buddhist, my journey toward enlightenment will be that much slower, but I will still have another chance in another life. This is not the case for Christianity or for Atheism, and as such, the cost of being wrong about Christianity is greater (at least by this analysis) than the cost of being wrong about Buddhism. This is similar to William James’ idea about how ‘momentous’ a decision is: choosing not to live as a Christian is a more momentous decision than choosing not to live as a Buddhist.
The decision to live my life as a Christian is thus what William James calls a “momentous” one: it has weighty consequences. It is also what he calls a ‘forced option’, meaning that I cannot decide to merely sit on the fence and wait until I have more evidence available. Like the decision to get on a train or to get married, there is no middle position available: either I live as a Christian or I do not. I may decide to postpone serious thinking about the question until later, but then I have already made the decision (at least for the moment) to not live as a Christian. I thus find myself forced to choose one path or the other. I can switch paths at any time, but at any given time I am always on one path or the other. (Note that I don’t wish to imply that living as an atheist and living as a Christian are totally distinct paths that always diverge, nonetheless they clearly diverge in enough ways for me to speak of them constituting different paths.)
The Key Questions
So how can I decide whether or not I should live as a Christian? For me there are three main subsidiary questions that I need to address in order to arrive at an answer:
- What is the probability that Christianity is true? By ‘Christianity being true’ I mean that ‘Jesus really was the son of God who died and was raised for our sins, etc’.
- Is living as a Christian a morally good life? This is where I raise concerns such as being able to trust that God is good given apparent biblical atrocities, etc.
- What are the costs of living as a Christian? Here I don’t mean things like ‘won’t get to sleep in on Sundays as often’, I mean more substantive things like giving up other goals and priorities.
Currently I am most interested in answering 1, as I think this is the most important and most difficult of the three. As such, the rest of this essay will be concerned with this question. I may address 2 and 3 in a future piece.
What Role for the Holy Spirit?
Christians generally believe that becoming a Christian is not primarily/not only/not at all (depending on their theological dispositions) something one chooses for oneself. They generally believe that it is something that happens through the grace and intervention of God and the Holy Spirit. I do not wish to dispute this, only to highlight that this point seems to me to be not particularly relevant to my enquiry here. Should I just wait until the moment when God decides to make himself known to me in a way that I will accept, ‘road to Damascus’ style? Whatever the exact role God may or may not play in the process, I still need to decide how to live, and I need to go about answering this question in the best way I can. I can’t control what (if anything) God decides to do for me, and so I find it useful just to speak as if converting to Christianity were something entirely up to my own volition, even if, theologically-speaking, many Christians would not agree with this. Thus, I’m using this language as a shorthand so that I can avoid making this qualification every time.
The Need to Consider Plausibility
How can I decide how likely it is that Christianity is true? In considering this question, it is important to understand what I mean when I talk of probability or plausibility. The fact of the matter is not probabilistic – either Christianity is true or it isn’t. But since I don’t know what the fact of the matter is, the question becomes one of how confident I can be given the evidence that is available. That is, how strongly does the evidence support the contention that Christianity is true over alternate possibilities? I think it absurd to say that it is impossible that Christianity is true, and likewise absurd to say that it is impossible that it is false. Maybe one quarter of both my atheist and Christian readers alike will now find themselves disagreeing, but so be it – I feel quite confident in claiming that neither extreme can be justified. Having ruled out certainty in either direction, I am left in the uncomfortable middle position of having to weigh up relative plausibility. This is no easy task, and so we are led back to our initial question – how can it be done?
Evidence and Truth-Tracking
It is my view that there is only one useful way (meaning ‘a way that actually helps us to achieve our object’) to go about answering this question, and that is by utilising what I (very broadly) call “reason and evidence“. Although there are always more subtleties and complexities than can be gone into at any one time, for now I’ll define “reason and evidence” as being those things that help us, with some better than chance degree of reliability, to ‘track the truth’ of propositions in some relevant subject domain. This notion of truth-tracking is subtle, but extremely important. Informally (I can present a more formal analysis another time for those desiring of more rigour), something is truth-tracking if the presence or existence of that thing tends to go along with, or be indicative of, the truth of certain propositions in a particular domain.
Consider the simple example of tossing a coin. My looking at the coin and seeing which side it landed on (in general) reliably tracks the truth as to what side it actually landed on. If I close my eyes and make a random guess, this does not reliably track the truth of what side it actually landed on. If I was incredibly tired and removed my glasses, my looking at the coin would probably less reliably track the truth as to what side it actually landed on, but would probably still be better than random guessing. Thus truth-tracking is an inherently probabilistic notion, always a matter of degree.
To take a more relevant example, suppose I find an argument for God’s existence which, upon consideration, I find to be quite compelling. Rather than merely assuming that because the argument seems compelling to me, that therefore the conclusion is likely to be true, I ought to ask myself ‘how reliably truth-tracking is the process of people like me analysing such arguments about God’s existence?’ The answer is, in general, that this process is not very reliably truth-tracking at all, as so many intelligent and honest people come to such different conclusions despite going through essentially the same process. I am therefore very wary of any argument which relies on me (or any other lone person) coming to a conclusion on the basis of their own analysis when there exists substantial disagreement on that question among epistemic peers (a consideration which, it should be noted, makes me at least somewhat less confident about nearly everything I say in this piece).
It is often difficult to determine how reliably truth-tracking any given type of argument or mode of reasoning is. However, difficulty in making such a determination does not entail that the concept has no value. It seems that we can say with reasonable confidence that beliefs based on widespread scientific consensus are quite reliably truth-tracking, those based on consensus of historians are somewhat less reliable but still fairly good, arguments that appeal to careful philosophical investigations are quite unreliable but probably still better than naïve unreflective opinion, while convictions based on subjective personal experience are often very unreliable at tracking truth. I wish to emphasise that this does not constitute an adoption of some form of scientism. Subjective personal experience can often be a reliable truth tracker (e.g. how hot is it today?), but I don’t think it very reliably truth-tracking for questions of the sort ‘how likely is Christianity to be true?’. For our purposes here, therefore, I believe it is accurate to say that scientific sorts of evidence are much more reliably truth-tracking than personal experiential evidence.
Needless to say, if I knew what the truth was, I would just believe that, and then I wouldn’t need to worry about all this nonsense about plausibilities and truth tracking. But since I don’t know of any place where true beliefs rain from the sky or grow on trees ready for the picking (that is, there is no easy way to just get straight to true beliefs without mediating processes), I must resort to the next best thing – finding methods that track truth and apply them as best as I can. This won’t guarantee that I hold true beliefs in the end, but given that I don’t know what the truth actually is, this method gives me better chances than any other.
Starting Points: Atheism and Agnosticism
Having established some basis for how I will conduct my analysis, I will now say a few words concerning my starting point. Of course, this is really only a hypothetical starting point, for in practise we all start from wherever we happen to be at the moment, bringing all our personal experience, knowledge, biases, and quirks with us. Nonetheless, I think it can be helpful to consider such a hypothetical starting point as a way of framing one’s thinking. Understood in this manner, therefore, I start from a position that I call atheistic agnosticism. Let me explain each of these terms.
I start from a position of atheism, because I believe that absent a reason to believe something, the proper default position is not to believe it. Crucially, this is not the same as saying that one disbelieves it. Consider “there are an even number of hairs on my head at this moment”. I do not believe this proposition, for I have no reason to. That does not, however, mean that I affirm its converse, “that there are an even number of hairs”, which would be equally unjustified. In this sense I am agnostic: I do not know. I begin the enquiry about Christianity, therefore, as an atheist in the sense that I do not affirm the proposition ‘God exists’, and an agnostic in that I do not have any particular reason to prefer atheism over theism.
I believe that in order to shift from this position of agnosticism and move my confidence in one direction or the other, it is necessary to have, as I say, ‘reasons and evidence’. Remember that by this I just mean things that help me to reliably track the truth of whatever proposition I’m examining. Thus, saying ‘I need a reason to change my beliefs’ is, for me, tantamount to saying: ‘I will only alter my best guess about what is true away from the initial agnostic position because of some factor which I have reason to believe will reliably improve my best guess about what is true’. So I’m not looking for reason or evidence that feels compelling to me, or that helps me to convince others, or that (by some other standard) grants sufficient epistemic ‘warrant’ or ‘justification’ to my belief. I am looking for things that will help me track the truth, so that I can increase the chances that my belief will be accurate, given that I start out from a situation of not knowing what the truth is.
Four Types of Arguments for Christianity
Having laid out this rather extensive groundwork, I will now fairly briefly consider four broad classes of reasons that I have heard offered in support of increasing one’s credence in the truth of Christianity. I find some of these arguments more compelling than others, in the sense that some of them cause me to raise the plausibility I assign to the truth of Christianity more than others, but ultimately none of them cause me to increase my credence by enough to push me above some fuzzy but nonetheless real threshold beyond which I would be willing to affirm the truth of Christianity. For each type of argument, I will briefly explain why I find it lacking.
Philosophical Arguments for the existence of God
This includes the cosmological argument, ontological argument, teleological argument, etc. Philosophers are not the experts on God’s existence, but they are expert on the question of evaluating the strength of philosophical arguments. As such, I regard the collective opinion of professional philosophers to be more reliably truth-tracking than my own personal attempts to evaluable these arguments. Since philosophers are a state of fairly considerable peer disagreement concerning the strength of philosophical arguments for God’s existence, some being persuaded by them, while others are not, I find it hard to accept that the strength of the argument s is sufficiently strong either way for me to reliably make a large update to my opinion in either direction.
On balance, I do think that arguments such as the cosmological argument and the fine-tuning argument constitute some reason for increasing my credence in the proposition that God exists, however because of the immense disagreement surrounding them (and also the many unknowns to which such arguments necessarily appeal, such as knowledge about the nature of time, causation, and possible alternate laws of physics), the amount by which my credence is increased is not large.
Arguments based on the Bible
This category includes arguments based on the power, majesty, coherence, transforming influence, beauty (etc) of the bible. Such arguments are, I think, even weaker than philosophical arguments, in the sense that the fact that one may find a particular holy text to be very powerful, transforming, coherent, etc, is clearly not a very reliable tracker of whether that text is actually true. All one need do is examine what Mormons say of the Book of Mormon, Muslims of the Koran, Buddhists of the Pali Canon, Hindus of the Upanishads, Sikhs of the Guru Granth Sahib, and many other such examples, to see that this method of arriving at beliefs about religious texts is exceptionally unreliable. Most people who read a religious text and find it to be compelling nonetheless are not followers of the correct religion (whichever religion that turns out to be).
Even worse, there are no real criteria on which to judge these sorts of properties. Philosophical arguments are often difficult to judge objectively, but at least there are some clear and agreed upon standards for doing so. In the case of comparing holy texts I would say there are none at all, and that all judgements made concerning the beauty, coherence, and power of such texts are fundamentally little more than subjective reactions which are not truth-tracking in the slightest. Muslims say the Koran is without comparison among any book written by man. Christians say it isn’t. Who is to judge? I know of no criteria on which this can be decided (note that I’m not talking about criteria for historicity. I’m talking about beauty, coherence, power, etc). In the end, I simply find no good reason (again, read ‘truth tracking reason’) to shift my belief in response to considerations such as these.
Subjective and Experiential Reasons
Subjective, experiential, personal reasons for believing in Christianity are not reliable trackers of truth, for essentially the same reasons noted above. Namely, such reasons are clearly not truth-tracking given the immense amount of religious disagreement. Millions of people from dozens of religions around the world and throughout history have reported all sorts of spiritual, supernatural, personal, mystical, divine experiences which have been immensely formative and persuasive for them, and on which they believe their own particular religious beliefs can be justified. Given that such experiences are so diverse and contradictory, however, it is clear that this is not a reliably truth-tracking process for forming beliefs about any particular properties of the divine. Some people think that these are all different manifestations of the same underlying God or spirit, but Christians (generally) do not believe this. Christians believe that they have correct beliefs about God and other religious have incorrect or less correct beliefs. If we are to determine the truth of this claim, we must seek out evidence beyond from subjective religious experiences, for these equally well support essentially all other religious claims. I think subjective religious or spiritual experiences can have value in helping one to stay committed and motivated in one’s chosen faith, but not in providing evidence (in the sense I understand it) that the path one has chosen is the correct one.
Historical Evidence for the Resurrection
The historical evidence for the resurrection of Jesus is, in my view, by far the strongest piece of evidence in favour of the truth of Christianity. Nevertheless, after a great deal of thought and consideration, while I do find that it constitutes a reason for thinking Christianity more probable, I do not think it provides sufficient evidence to overcome the countervailing factors I discuss below. I outline my thinking on this point in detail in my HBS model of the resurrection appearances. In very brief terms, I believe that human psychology and sociology is more than capable of explaining what took place with Jesus’ followers after his death, and that no reference to supernatural interventions is warranted or necessary to explain the way events unfolded.
Three Arguments Against Christianity
I will now, again very briefly, outline some considerations that lead me to think that Christianity is relatively less likely to be true. These reasons are not definitive, but I do think they hold some value as being somewhat reliable in helping me to arrive at true beliefs.
The problem of evil/suffering
I believe that the existence of the immense quantity of apparently pointless suffering in the world is less likely in a universe governed by an all-powerful and all-good God as posited by Christianity. It is true that such a God may have reasons or constraints unknown to us that explain the continued existence of such evils, however I do not believe I have any reason to believe that such reasons or constraints exist. Merely stating this as a possibility does not change the fact that, given what we do know, the amount of suffering that exists in the world and lack of any evident reason for much of it is more consistent with a universe that is not governed by a Christian God than in a universe that is. As such, I believe this constitutes a reason to lower my credence in the truth of Christianity by some non-trivial (though not enormous) amount.
The Problem of Religious Confusion
This problem mirrors concerns raised above about religious disagreement and diversity. It seems to me that the Christian proposition that God wants all mankind to enter into a relationship with him is less consistent with the immense plurality of religions and of apparently genuine religious piety and experience, than the proposition that religion is an invention of man (or also the proposition that God is indifferent to which religion we follow). Again, there may exist reasons why God allows so much apparent religious confusion and competing revelations, etc, however as noted above, the mere possibility of their existence does not alter the fact that we do not know of any such reasons, and yet we do know that religious confusion exists, and seems to conflict with a Christian God’s desire to relate to all of mankind. As such, I consider the problem of religious confusion/divine hiddenness to be a reason to lower my credence in the truth of Christianity. Again, not by an enormous amount, but by an amount that is not insignificant.
Evils done in the name of Christianity
This includes such things as Old Testament atrocities allegedly commanded by God, misogynistic teachings of parts of the Bible and many churches historically, events such as the crusades and inquisitions, Christian homophobic teachings and doctrines, and other such things. None of these are definitive, and indeed I probably regard them as weaker than the previous two concerns, however I do feel that they mitigate somewhat against the plausibility of Christianity, so I include them here.
The brief analyses of the various arguments I have provided above will no doubt be unsatisfying to many readers. They are intended more as summaries of my thinking and as starting points for further discussion, rather than as comprehensive or definitive accounts. All in all, after considering the arguments, I am left in a position of thinking that the reasons advanced for increasing my credence in the truth of Christianity are outweighed by the reasons to reduce my credence, and so are insufficient for me to be willing to affirm the truth of Christianity. (Note, however, that I am less confident about my ‘reasons against’ than I am that the provided ‘reasons for’ are insufficient).
Returning to my original question, I find that the probability that Christianity is true given the truth-tracking reasons I have available is too low for me to feel like becoming a Christian is the best decision for my life. This is where I currently stand, acknowledging a great deal of uncertainty and ignorance on my part. I am constantly searching for additional reasons, new considerations, and previously unconsidered evidences that may lead me to change my mind. Indeed, I think I have good reason to expect to find at least some such reasons and evidences, as I have changed my mind about such things several times in the past. My opinion is therefore provisional and subject to change as I learn and think more. That said, I will not change my beliefs without reasons of the sort I have described. I want to believe truth things and live my life accordingly, and truth-tracking reasons (or something very much like them, even if I choose to abandon that particular mode of description) are the best way I know of achieving this, given the state of ignorance in which I begin.
I would hope others would join me in this quest for truth, and that we can aid each other in pursuing our end with firm resolve, not wavering, without fear for what false beliefs we may need to give up, or new true ones we may need to adopt. This journey is not easy. We must not get complacent because of the comfort of a waystation we find along the way. As long as ignorance remains – and for us humans it always does – the journey must go on. We must not be satisfied with anything less than beliefs that are as true as we can reasonably make them. For questions as important as those we consider here, nothing less will do.
