When talking about the "real" Christians, also don't forget the monks and nuns who go about preaching and doing charity and missionary work. I believe those are just as important as the "lay folks".
Another thing I learned this past year at school is that if it weren't for the Church in the Middle Ages (monasteries more specifically), a lot of our classic literature, and quite possibly our written language, would have been lost, because the monks were the only people that copied books and manuscripts until the printing press came around.
And lastly, ADM:

That made me chuckle.
