One of the most peculiar features of the belief in God is the accompanying claim that God is an indescribable mystery, an object of faith but never an object of knowledge. In certain contexts – in worship, for example – this claim undoubtedly serves a useful purpose; and so I do not want to dismiss the idea altogether. But when pious remarks about the ineffable nature of God are taken out of context and turned into philosophy, the result is usually an epistemological muddle. The trouble, of course, is that those who insist on God's mysteriousness still manage to say all sorts of things about him; he is an incorporeal spirit, he created the world, he loves his creatures, and so on. To assert these things is to presume some understanding of God, but no understanding is possible if God is completely incomprehensible. So if that is how it is, if the object of religious belief is utterly incomprehensible, then it makes no sense to say – or believe – anything about God.
