The Biblical concept of marriage is not how we conceive it today. From a Biblical perspective, women are property of their family until their husband's family pays a bride price and they are married to their husband. From then on, that woman is the property of her husband and husband's family. This is why rape is considered a property crime in the Bible. For example, Biblically, if a man were to rape a woman before she was married, he is to pay restitution to her family as she is now worthless to them having been raped. If she doesn't cry out while being raped, then she is to be stoned to death as that would mean she was obviously complicit (Never mind, her rapist could have held a knife to her throat). If she is impregnated by her rapist, then her rapist is to pay a bride price to the family and marry her.
My point in all of this is that there is no way you could have a Biblical gay marriage because such an arrangement was utterly inconceivable to the Bronze Age desert wanderers that originally wrote the Bible. See that's the thing, you have to put this in its Bronze Age historical perspective. The people that wrote the Bible would make the Taliban look Woke. Granted, 2000 years of Christianity has slowly sanitized and reformed the original beliefs, but you can count on them using those original beliefs anytime they want to pull the religion card with a group they don't like, like the gays.
