In the Bible, in the book of John, Chapter 8, we find the story of the adulterous woman who was brought before Jesus. According to John, the pharisees (the lawyers of the day) said to Jesus that the law from Moses decreed that she should be stoned to death. They asked Jesus what should be done. And Jesus said, “Let he who is without sin cast the first stone.”
I think this tells us that we should have a constitutional right to privacy. Consensual private acts between adults should not be regulated or punished by the mob or the state.
But we have a ton of ‘Christians’ on the religious right that clearly want to be judgmental with respect to gays. Jesus told us to judge not, lest we be judged.
Even if you feel convinced strongly that homosexuality is a sin, according to the Lord’s prayer, Jesus said we should pray to God to “forgive our trespasses as we forgive them that trespass against us’.
We need to be forgiving and act with grace with respect to sexual acts between consenting adults. We don’t need to be judgmental.
Let he who is without sin cast the first vote for defense of marriage.
