"To have faith in a religion, any religion, is to accept at some primary level that its particular language of words and symbols says something true about reality. This doesn't mean that the words and symbols are reality (that's fundamentalism), nor that you will ever master those words and symbols well enough to regard reality as some fixed thing. What it does mean, though, is that you can 'no more be religious in general than [you] can speak language in general' (George Lindbeck), and that the only way to deepen your knowledge and experience of ultimate divinity is to deepen your knowledge and experience of the all-too-temporal symbols and language of a particular religion. Lindbeck would go so far as to say that your religion of origin has such a bone-deep hold on you that, as with a native language, it's your only hope for true religious fluency. I wouldn't go that far, but I would say that one has to submit to symbols and language that may be inadequate in order to have those inadequacies transcended.
This is true of poetry, too: I don't think you can spend your whole life questioning whether language can represent reality. At some point, you have to believe that the inadequacies of words you use will be transcended by the faith with which you use them. You have to believe that poetry has some reach into reality itself, or you have to go silent," - Christian Wiman, "Notes on Poetry and Religion," from Ambition and Survival: Becoming a Poet.
