I have trouble with the notion that Christianity is per force a pacifist religion. We have that nagging little thing in Matthew where Jesus is quoted as saying, "I come not to bring peace but the sword." That gets glossed over lots. I don't know why a cohort was sent to Gesthemene to arrest him if he was known to be so peaceful. One of his guys lopped of a centurion's ear, presumably with the sword he brought instead of peace.
