Allow me another angle. There is nothing in the Scripture about “gay” or “gaiety” being a sin! Once you accept the euphemism for whatever, pederasty in this, or abortion in another case, you’ve thrown a white flag. There is no discussion. Of course gaiety is welcome in all churches! And is there anything in the Bible forbidding “choice”?
I’m not sure I understood where you are coming from in your approach. When a man lays with man as he would with woman, that is an abomination before God. This is in the Bible. The translation from the Greek for the word ‘abomination’ gets a little watered down as it moves to English.
In the NT, Jesus describes in detail precisely what marriage is. Man and woman becoming one flesh.
There is precisely zero in Scripture to support homosexuality. There is zero biologically to support homosexuality as ‘natural’. In point of fact, it is a complete inversion of the Divine Intent. A mockery of the Divine Intent.
If there were a stronger word in English for ‘abomination’, that would be the one we would use. ‘anathema’, perhaps.
Murder, rape, stealing a pack of gum, and sucking a live baby out of a woman’s uterus are all sins. They all keep you out of Heaven.
