even then, Leviticus are all Jewish laws.
The whole book of Leviticus was written for the Levites, God's chosen people, and one of the twelve tribes of Isreal that was given the right to contact god. They became priests.
The whole book is laws for these priests and for the Jewish people in order to remain clean enough to worship God, as Prayer wasn't a thing because Jesus hadn't died on the cross, therefore there wasn't a bridge from the earth to heaven and all that.
For context, let me explain a little about the system of Prayer before Jesus.
There was a temple, and in the temple, the Ark of the Covenant was held, along with incense and a sacrificial table for sacrifices. The Priests were the only ones allowed to enter the Temple, they were chosen by god, and they had very specific rules to follow in order to be clean enough to be in the presence of God. Those rules were the rules like don't eat pork or bottom-feeding fish. Don't wear mixed cloth and stuff like that. They had to wear specific clothes when they entered the temple and they had to wear a rope tied to their ankle, their robes had bells along the bottom, and here's why. As soon as the priest crossed the veil, into the temple, if the priest had broken any of the rules, or was "unclean" he would drop dead, the bells would stop ringing, and they would have to pull them out with the rope, because again, no one could cross the veil unless it was a priest, and even then, they could still die.
That is the whole book of Leviticus, rules for the priests and jews.
And here's why they are irrelevant, and the book is there solely for the history of Christianity.
When Jesus died on the cross, the "veil was torn in two" with a great earthquake and the sky went dark. This is very important
Matthew 27:51
"When Jesus had cried out again in a loud voice, He yielded up His spirit. At that moment the veil of the temple was torn in two from top to bottom. The earth quaked and the rocks were split. "
This is signifying that, now that Jesus has died for our sins, we no longer need a veil or priest, now anyone can pray, because our sins have been paid for. Now that we don't need priests, we don't need the laws for those priests, and therefore, Leviticus means nothing to us. And so when someone brings up that scripture, even though it's mistranslated, they still like to push it, so this is what I tell them, because even if it did mean homosexuality, it doesn't matter anymore.
(I have done a shit ton of research on this, my dad is a pastor, I have read the bible my whole life, I have met with people who literally went to college to study these things. I know what I'm talking about. But again, I'm agnostic, so take it or leave it ig.)
