You are totally missing my point.
Jesus was able to forgive because he is God. Man cannot forgive sin. Man's law is different than God's law, (although man's law must attempt to reflect God's law.)
As for God's law on Homosexuality it is clear.
Do you not know that the wicked will not inherit the kingdom of God? Do not be deceived: Neither the sexually immoral nor idolaters nor adulterers nor male prostitutes nor homosexual offenders 10nor thieves nor the greedy nor drunkards nor slanderers nor swindlers will inherit the kingdom of God. 1 Cor 1:9-10 (NKJV)
God will punish homosexuality, fornication and adultery in his way, but that does not relieve man of his responsibility to prohibit behavior under our law that destroys public morality.
This is what I am talking about. This is what our founders believed, this is what the Puritans believed, this is what John Calvin believed.
You'd be better off spending your energies to convince people of the errors of their ways than you would playing super spy of the bedroom.
A little testy, aren't we? I can't believe you really think we should execute people who have premarital sex or say "Goddamnit!"
