//A moral code based on the absolute authority of God, and not some dynamic version that changes over time.//
So is homosexuality a sin?
The OT demands that homosexuals be stoned to death and the NT regards them as worthy of death.
The book of Revelations tells us that they are left outside, (IE, Hell) along with murderers, occultists, drug users and idol worshippers.
(Rev 22:15)
I suspect that you may interpret this verse in a way that suits you?
