“Killing them for being gay doesn’t work for me, and I am pretty sure Christ would be unhappy about it as well.”
Leviticus 20:13
If a man has sexual relations with a man as one does with a woman, both of them have done what is detestable. They are to be put to death; their blood will be on their own heads.
Romans 1:26-27
Because of this, God gave them over to shameful lusts. Even their women exchanged natural relations for unnatural ones. In the same way the men also abandoned natural relations with women and were inflamed with lust for one another. Men committed indecent acts with other men, and received in themselves the due penalty for their perversion.
However, there is forgiveness after repentance and rejection of homosexuality.
Good luck with scraping through Leviticus. You may want to read it entirely.
