Chrisitians are bound by the 7 Noahide Laws and 10 Commandments given by YHWH at Mt Sinai. There are 613 commandments. One of these commandments Christians have no responsibility to uphold (because supercessionism) is:
“Thou shalt not lie with mankind, as with womankind: it is abomination.”
This is Leviticus 18:22, part of the Holiness Code. Then there’s this:
“If a man lies with a male as with a woman, both of them have committed an abomination; they shall surely be put to death; their blood is upon them.”
This is Leviticus 20:13.
Since Christians are not bound to uphold all 613 commandments (juist 10), Christians are explicitly allowed to do whatever Leviticus prohibits. Christians are not bound by laws mandating one keep kosher. This obviously has been taken to mean: Go to town.
If Leviticus, in these passages, prohibits males from having sex with males, which it doesn’t, this means male Christians are explicitly allowed to have sex with males.
Simply: If eating pork is OK, then male-male sex is OK.
Also, God is gay.
