The word "sin" will only be used when describing right wing conservatives who are "judgmental". Indeed, I foresee a time when the US Episcopal Church updates the Bible to rid it of any negative references to homosexuality.
Verses in Leviticus and Deuteronomy regarding punishment for homosexuals will be deleted or re-translated. The "sin" of same sex relationships will be replaced by the "sin" of non-consensual sex between men and men, women and women, adults and children, adults and animals. As long as the man, woman, child, or sheep is a willing participant in any type of "loving" sexual relationship, then Episcopalians can be expected to support such behavior.
The Bible, after all, is a "living document" in the way that the Constitution is a "living document". Times change, and the prohibitions against homosexuality, bestiality, and infanticide in the form of abortion must be updated to reflect a more enlightened world outlook.
Naturally, God wants us to change with the times, too. He wants us to replace the Book of Romans with the Book of Vermont. Corinthians shall be replaced by 1st and 2nd San Franciscans. The Gospel of John will be updated to the Gospel of John and Bruce.
God can hardly wait for the rest of His Church to become so enlightened....
The numbers on the membership rolls does not the body of Christ make, or as Corrie ten Boon said, "just because a mouse gets in the cookie jar doesn't make him a cookie." We once had a priest that was fond of saying that you won't find God in church unless you take him with you. Wiser words were never spoken. God commands His people to have nothing to do with the one who calls himself a brother yet is wallowing in his sin (my paraphrase), and if God's people are absent from the church, then so will God's Holy Spirit be.
"Many will say to me in that day, Lord, Lord, have we not prophesied in thy name? and in thy name have cast out devils? and in thy name done many wonderful works? And then will I profess unto them, I never knew you: depart from me, ye that work iniquity." (Matt.7:22-23)
Expect this to happen soon after the current Bible is ruled "hate literature" by the courts.
Things are moving on schedule.
