Keep your version of 'God's law' for your own denomination and congregation, thank yoy; the Crusades ended centuries ago.
''My version''? There's really only one way to interpret this:
''Thou shalt not lie with mankind, as with womankind: it is abomination.'' - Leviticus 18:22
This law may be from the Old Testament, but it still applies today because it is a moral law, as opposed to a ceremonial law (such as the prohibition on eating pork, for example).
If you interpret it literally, it means don't have vaginal sex with a man.
