I'm a priest (Episcopal Church) and one of the things that I frequently remind my parishioners is that Christianity is intended to be a practice, not a belief. What's happened is that the term "Christian" has been severed from any concrete form of practice (by utilizing the whole "faith, not works" thing and misconstruing it). When Jesus says "I am the way, the truth, and the life" He's using active language (a way can only be walked, truth sought, life lived). But so many Christians have turned that saying into something about precepts.
