The idea that there is simply nothing worthwhile in religion is as unlikely as the idea that there is nothing worthwhile in poetry, art, philosophy or science. On the other hand, taken at their literal word, many religious claims are at best unjustified and at worst absurd or repugnant. There may be deep truths in religions, but these may well not be the truths that the religions themselves officially proclaim. To borrow a term Jürgen Habermas employs in a different context, religions may suffer from a “self-misunderstanding” of their own significance.
"Self-misunderstanding" is one way of putting it; "hypocrisy" would be a less charitable term.
Knowledge, if it exists, adds a major dimension to religious commitment. But love and understanding, even without knowledge, are tremendous gifts; and religious knowledge claims are hard to support. We should, then, make room for those who embrace a religion as a source of love and understanding but remain agnostic about the religion’s knowledge claims. We should, for example, countenance those who are Christians while doubting the literal truth of, say, the Trinity and the Resurrection. I wager, in fact, that many professed Christians are not at all sure about the truth of these doctrines —and other believers have similar doubts. They are, quite properly, religious agnostics.
I celebrate those whose faith brings them comfort and love. I never disparage somebody's faith.
Prostilyzation and hyprocrisy, on the other hand, I find to be intolerable.
