I had a very brief look at son of God by angela tilby and there was mention of Jesus. or chrestus by Sutonian and also by Tactitus who was a Roman Historian. I haven't got time to read the book again at the moment but that is where i was coming from.
also he was a Jewish peasant so he would not exactly be high priority but nevertheless he is mentioned. maybe my phrasing wasn't brilliant last night.
Also this may be contraversial as well but just to highlight where christians may come from on the homosexual and lesbian thing from the New International Version
1 Corinthians chap 9, v6
Do not be deceived: Neither the sexually immoral nor idolaters nor adulters nor male prostitues nor homosexual offenders etc etc will inherit the earth.
there is also a verse in Romans 1 26 about women talking of natural and unatural relations. in romans 27 it talks about men committing indecent acts with other men etc.
In leviticus 18.22 which has already been mentioned again a similar flavour.
I don't know as i am a straight hetrosexual. I am not trying to be judgemental just putting in biblical quotes as to why this women may have this opinion.
also i don't think God is overly keen on sex outside of marriage which is something alot of christians struggle with myself included
It should be noted that Islam isn't exactly pro homosexuality either.
