Interesting thread. I think it does come down to interpretation though. In my humble opinion, the Bible can be interpreted in so many ways that it's validity as truth is completely irrational. It's a series of stories written by men.
As far as Jesus' take on homosexuality, that message was very simple IMHO. Love the unlovely, love your neighbor as yourself, anything you do to the least of them you do to me, I am the vine ye are the branches, forgive seventy times seven, and turn the other cheek. Although there is NO proof of a Jesus Christ, it's sort of traditional when it comes to humankind passing on stories. So in the department of Homosexuality, who knows?
One thing I would like to point out though is the condemnation delivered in all religions. Doesn't matter what Bible they are using or who's interpretation they use, I think they all distort these messages to best suit their needs at the time. Besides, if these ideas of God or Jesus were actually among us as humans or beast, we'd kill them anyway and the religions would cry out - Blasphemy!
Not so sure there is an answer to your question and trying to understand all religions is like trying to understand ALL men and women. I think the important thing to understand is that we're all blind and we're all following another blind man. Not many know truth but they claim to. Heck, they all claim that they are correct and their doctrine is the only truth... BS, all of it.
This is only my opinion and after careful research and discovery, and searching up and down for answers, all I can come up with is that humankind is disconnected from the source of who we are and we disconnect ourselves with phony doctrines and myths.
Oh, I wanted to add that our church was Episcopalian. When they decided to allow gay ministers in the church, the church I was raised in condemned them for this because it's unacceptable. For months the toil in the church and the arguments of who owns the property and the words of condemnation delivered from the pulpit as everyone sits there as zombies listening intently to some silly man up there fills their head with hatred towards the Episcopal Church. Needless to say, it was on the news and there were court battles and lots of slapping of other religions around until finally, they became non-denominational and were able to keep their building. All the while, they claim to have been saved by the blood of the Lamb - Jesus Christ. After years of listening to the message of Jesus Christ and then seeing this event take place in my own church, that's when I decided unequivocally that they are all full of crap. Praise the Lord!
