TheGunny simply quoted Christian scripture to you. Are you, then, saying that Christianity is just another of these many "dogmatic value systems?" I contend that it is not, and that it is not explicable by the facile explanations of atheists, such as that religion is a psychological crutch which makes believers feel secure; actually, Jesus promised his disciples they would have trouble in the world, that they would be persecuted and killed. If religion is just a means of enforcing external order, why did Jesus teach that it's not following rules which is important, but the content of your character? He ridiculed people who were sticklers for rules.
I think the unique nature of Christianity just might explain why TheGunny is confident that he does have the only truth.
