What? Perhaps burning innocent people is wrong because they are innocent.
If they are guilty of being witches is it OK to burn them by your standards?
Stone them. God specifically said stone them. Matthew apparently sez, as per Tribune7, that stoning is null and void, although being a witch is still a sin. Since stoning was verboten, I guess burning was taken to be prescribed. I believe it satisfies the golden rule, since, if you were a devout deputy of the inquisition, you'd want your soul scoured in the cleansing fires of God's Mercy were you to be shut off from God by witchery.
How say you Tribune7? Have you found a clear formulation for God's Law, as modified by the Gospels, that explains why I can't be a witch, but I can be a pig-eater?
