Religion is only cost-effective if you’re poor, or a religious bureaucrat/leech. Note that Xian “rightists” oppose anti-poverty relief and universal health care. They want a sicker, poorer America more in need of religious fantasies.
My understanding is that the Noachide Laws are part of Jewish theology (what non-Jews should do to be good with יהוה), not of Christian theology.
I know my pastor supports SSM because he’s in one.
Some scholars actually believe that the Levitical statement about male homosexuality is actually about pedophilia.
Christian theology is all over the place. I’ll grant it does seem to be at least a superficially sound way for Christians to pretend like the OT (with large swathes of “thou shalt nots”) does not apply to them. Covenantism and dispensationalism are the other two (either god makes new covenants all the time, and most recently for Christians with Jesus and some of the more flowery, less judgy things he said, or god dispenses new knowledge that “clarifies” what is really moral, all that stuff he said before notwithstanding).
Because of course you can find a justification for just about anything in scripture if you read it right, including mass murder and rape.
