Thanks for this. It's a tricky situation. Christians basically see the "religion" as an effort to divinize reproductivity. This involves four rituals of which the Bible is totally unaware: christening, baptism, wedding, funeral, to mark the occasions of birth, adolescence, marriage, death. Fill in the blanks with Bible chit-chat and you're really loving Jesus.

The Catholics solved the queer problem by making them clerics and shutting them up behind walls. But Protestants, trying to control populations sheerly through sexual regulation, were left with the problem from hell. Can they regulate queer sexuality by doing the four rituals and making them honorary straight people? Some wish to try.

I'm nervous about your suggestions. If telling Christians to enforce the OT rule against false witnesses, you're stripping the penalty (cf. Exo 20:16; Deut 19:18–21) which is to punish the accuser on the terms of the crime which was being accused.

Can you just raid OT law for some concepts? That's what you'd lamented re. Lev 18:22. You try to neutralize some apparently restrictive OT passages through scholarly theories, which leaves a void: why would one be part of the religion? If regulating the body and creating an endogamous community is the point, as in much of Protestantism, then your suggestions destabilize that model. If marriage is the central practice then "plural relationships" are very unwelcome.
