By what authority?
The authority that gave us the Bible, the Church founded by Jesus.
There were a multitude of Churches scattered around the Roman Empire after Christ. They each had different literature, all kinds of scraps of writing, there was no Bible. Some had scraps that made it into our modern Bible and some had stuff that was excluded.
Early Christians rejected Paul's letters.
The final form of the Bible ended up with at least three, the Orthodox, the Catholic and the more recent Protestant.
So which of the three do you regard as God's "official" word?
What about the numerous verses in the NT that are forgeries? do you treat them as God inspired?
Why would Jesus even need to speak about homosexuality?
Exactly, so why would you?
It was already covered in the Old Testament. Any sex outside a marriage between a man and woman is adultery, though homosexuality is even worse.
There are lots of things to be found in the OT, like the sabbath is sunset Friday to sunset Saturday and eating pigs is unclean and the stoning of women who commit adultery, do you adhere to these directives too?
He gave the apostles the power to make binding laws. The church has always condemned homosexuality.
The Christian cannon can be said to have begun with the Gospels, yet none of them discuss homosexuality, so you are clearly wrong to say the Church has "always condemned homosexuality".
Furthermore there is no single "the Church" just hundreds of divided and opposing sects who each claim there way is the true way.
Tell us, would you teach your kids to be homosexual?
No, but as is the magat custom you want to
conflate things, in this case my personal disinterest as advocacy. I don't care how people unite, I don't care, let God worry about others conduct and judgement, we must each focus on our own flaws.
I really think you'd be more at home under a fundamentalist Islamic regime, your a typical bible bashing white supremacist fundie who is driven by hatred and fear and phobia not love, just another fake Christian.
