Thing is this. It IS true that the Apostle Paul condemned homosexuality in the NT. Christ isn’t quoted addressing that subject directly. However, CHRIST kept the whole OT law; so it’s a given he wasn’t approving queer behavior. Paul also kept the law as much as a human is able. - My mother used to say it was just a nasty habit that some men & women got hooked on. I agree.
We believe in a triune God, do we not? We also believe the Bible, including the Epistles are the divinely-inspired word of God through the Holy Spirit. Therefore, whatever Paul wrote, inspired by the Holy Spirit implicitly brings with it Christ’s imprimatur. Since God the Father, Christ and the Holy Spirit are one, there can be no conflict.
