I am a Christian homosexual who has always been in a monogamous relationship. Why can’t this be as acceptable as a heterosexual married couple committed to only one person?
Now, even when and where society legalizes homosexual marriage, this does not mean God recognizes it as a marriage. If society legalized marriage between an adult male and a six year old girl, God is not bound to recognize it as marriage and withdraw his judgment that this is perverse. If society legalized marriage between a man and his sister, this would not thereby change God's revealed will on the sin of incest.
