For what it's worth, I notice that relatively few American Christians truly understand Christianity. I don't mean that they are mere hypocrites--after all, like a hospital, the church is a place for sick people--I mean that they really don't understand how to interpret the Bible, and they have virtually no awareness of the original church. The Orthodox understand it best of all (in my opinion), but many of us are, nevertheless, caught up in legalism and internecine ethnic struggles--but that's another thread.
The only thing we can do is pray for greater understanding for us all. St Paul tells us to avoid arguing with those who won't listen, and I think that's good advice. Let's trust in God and remove the log from our own eye first. Living in imitation of Christ is the hardest thing a person can do.
