Übergeek 바둑이: The OT has many laws that have been interpreted as laws on homosexuality. Many law interpretations based on the idea that God is purely male.. though it is clear when you read Jewish concepts that God is only male in regards to our relation with God, ie God the Father.

Certain texts are against rape of men by men as happened in Sodom, certain texts are to keep reminding the early Jews against being like the Canaanites. The laws on homosexuality some deem are purely on rape and temple based prostitution, and in some respects based on that man's seed was how babies came into being as at that time the female egg was not known.

How much comes from other religions is vague. It is to remembered that Moses learnt much from the Egyptians (see Corpus Hermeticum) .

As to NT texts, again interpretation is a problem. I would again say (based on OT) that the condemnations were on hetro people abusing same sex ie rape.

As to being modern interpretations... I cannot agree, so much we've lost from the early days through the killings and burnings during the formation of the Roman church.
