Hm...that seems a bit like the "No True Scotsman" fallacy. Moral standards change over time, and acts that were in accord with the Church (and public at large) of the 15th Century are now viewed by us with distaste.
More than "a bit" -- you are correct, I did stumble in that regard. I withdraw my assertion about "true representatives" of the Church.
I do, however, still maintain that the Jesus Christ described in the New Testament would be extremely unlikely to condone such behavior. He sounds to me like a pretty easy-going sort of fellow, who would give you the opportunity to believe what He said, or not; and would not kill you if you chose not to, but rather would only express the hope that you might change your mind before shuffling off your mortal coil in some other fashion later on.
