In fact, the Old Testament does not advocate the killing of gays by individuals. It does advocate making homosexuality a capital offense for a theocratic government. Ditto adultery. That's why (IMO) Jesus stopped the crowd from stoning the woman found in adultery. They were not members of the government and had not followed due process. The woman had not been subject to trial nor given an opportunity to defend herself, let alone repent.
The misapplication of G-d's word to the Jewish Government as G-d's word to the believer causes no end of grief.
Shalom.
Thank You, ArGee! It's amazing the amount of false or maybe just ignorant statements being made here regarding the Bible..
