Well, people could be thinking;
"The Bible is obviously not writen by god and accurate, it's people with faith in god telling us of what god was to them. And that ('what god was to them') changed in the past and is changing now. We now know that homosexuals are not abberent or dangerous. If they are in love, their love should be recognised and respected as much as that between a man and a woman. If the message in the Bible is to love each other, why would God want to exclude non-harmful loving homosexual people from fellowship with those of like-mind.
Just as we can see the influence of culture on the Mosaic Laws, so to we can discern sometimes the fundamental messages in the Bible - at least as many now see it - was obscured by a culture's bigotry. Biblical prohibitions of homosexuality, if indeed they are as explict as some believe, are a good example of this.
Now we can welcome people regardless of their sexuality, united in love and worship of god."
I had a problem with literalism in the past - it was like "do it 'properly', or don't bother".
I now understand that to define 'properly' is an impossibility, and that basically people have an absolute right to believe whatever they want for whatever reasons they want to, as long as they are excellent unto one another.
