Does It Matter Whether God Exists?

Discussions of religion are typically about God. Atheists reject religion because they don’t believe in God; Jews, Christians and Muslims take belief in God as fundamental to their religious commitment. The philosopher John Gray, however, has recently been arguing that belief in God should have little or nothing to do with religion. He points out that in many cases — for instance, “polytheism, Hinduism and Buddhism, Daoism and Shinto, many strands of Judaism and some Christian and Muslim traditions” — belief is of little or no importance. Rather, “practice — ritual, meditation, a way of life — is what counts.” He goes on to say that “it’s only religious fundamentalists and ignorant rationalists who think the myths we live by are literal truths” and that “what we believe doesn’t in the end matter very much. What matters is how we live.”

The obvious response to Gray is that it all depends on what you hope to find in a religion. If your hope is simply for guidance and assistance in leading a fulfilling life here on earth, a “way of living” without firm beliefs in any supernatural being may well be all you need. But many religions, including mainline versions of Christianity and Islam, promise much more. They promise ultimate salvation. If we are faithful to their teachings, they say, we will be safe from final annihilation when we die and will be happy eternally in our life after death.

If our hope is for salvation in this sense — and for many that is the main point of religion—then this hope depends on certain religious beliefs’ being true. In particular, for the main theistic religions, it depends on there being a God who is good enough to desire our salvation and powerful enough to achieve it.

But here we come to a point that is generally overlooked in debates about theism, which center on whether there is reason to believe in God, understood as all-good and all-powerful. Suppose that the existence of such a God could be decisively established. Suppose, for example, we were to be entirely convinced that a version of the ontological argument, which claims to show that the very idea of an all-perfect being requires that such a being exist, is sound. We would then be entirely certain that there is a being of supreme power and goodness. But what would this imply about our chances for eternal salvation?

On reflection, very little. Granted, we would know that our salvation was possible: an all-powerful being could bring it about. But would we have any reason to think that God would in fact do this? Well, how could an all-good being not desire our salvation? The problem is that an all-good being needs to take account of the entire universe, not just us.

Here, discussions of the problem of evil become crucial. An all-good being, even with maximal power, may have to allow considerable local evils for the sake of the overall good of the universe; some evils may be necessary for the sake of avoiding even worse evils. We have no way of knowing whether we humans might be the victims of this necessity.

Of course, an all-good God would do everything possible to minimize the evil we suffer, but for all we know that minimum might have to include our annihilation or eternal suffering. We might hope that any evil we endure will at least be offset by an equal or greater amount of good for us, but there can be no guarantee. As defenders of theism often point out, the freedom of moral agents may be an immense good, worth God’s tolerating horrendous wrongdoing. Perhaps God in his omniscience knows that the good of allowing some higher type of beings to destroy our eternal happiness outweighs the good of that happiness. Perhaps, for example, their destroying our happiness is an unavoidable step in the moral drama leading to their salvation and eternal happiness.

My point here reflects the two-edged character of religious responses to the problem of evil. The only plausible answer to the question, “How could an all-good and all-powerful God allow immense evils?” is that such a God may well have knowledge beyond our understanding. As David Hume suggested in his “Dialogues on Natural Religion,” the problem of evil is solved only by an appeal to our own ignorance. (There are powerful formulations of this approach by philosophers called “skeptical theists.”)

Such an appeal may save us from the apparent contradiction of evil in a world created by an all-good God. But it also severely limits our judgments about what an all-good God would do. It may seem to us that if we live as we should, God will ensure our salvation. But it also seems, from our limited viewpoint, that God would not permit things like the Holocaust or the death of innocent children from painful diseases. Once we appeal to the gap between our limited knowledge and God’s omniscience, we cannot move from what we think God will do to what he will in fact do. So the fact that we think an all-good God would ensure our salvation does not support the conclusion that, all things considered, he will in fact do so.

It follows, then, that even a decisive proof that there is an all-good, all-powerful God cannot assure us that we are ultimately safe. Even if we insist on a religion that goes beyond John Gray’s beliefless way of living, belief that there is a God leaves us far short of what we hope for from religion.

Many believers will agree. Their confidence in salvation, they say, comes not from philosophical arguments but from their personal contact with God, either through individual experience or a religious tradition. But what can such contact provide concretely? At best, certainty that there is a very powerful being who promises to save us. But there may well be — and many religions insist that there are — very powerful beings (demons or devils) intent on leading us away from salvation. How could we possibly know that the power we are in contact with is not deceiving us?

The inevitable response is that an all-good God would not permit such a thing. But that takes us back to the previous difficulty: there is no reason to think that we are good judges of what God is likely to permit. God may have to allow us to be deceived to prevent even greater evils.

We can, of course, simply will to believe that we are not being deceived. But that amounts to blind faith, not assured hope. If that doesn’t satisfy us, we need to find a better response to the problem of evil than an appeal to our ignorance. Failing that, we may need to reconsider John Gray’s idea of religion with little or no belief.
