That is an interesting reply from the bishop. He seems to be saying that if some people find it difficult to obey one of God's commandments, they are free to violate all of the other commandments.
Jesus said that the married couple, "are no more twain, but one flesh." He made it clear that God does not approve of divorce: "What therefore God hath joined together, let not man put asunder. " (Matthew 19:6).
Nevertheless, Jesus also said, "Moses because of the hardness of your hearts suffered you to put away your wives: but from the beginning it was not so." (Matthew 19:8) Divorce was allowed because people were not always able to live up to the Godly ideal of marriage.
I do not recall any similar allowance for homosexuality; everywhere it is mentioned in the Bible, sodomy is condemned in the strongest language. Moses did not allow it, as he did divorce. Indeed, the death penalty was prescribed for sodomy (Lev. 18:22), but not for divorce.
Frankly, I am surprised that the good bishop would not know any of this. I am even more surprised that he would describe as "hysterical" those who take the God's commandment seriously.
He knows it perfectly well. He just chooses to ignore it.
The mistake many orthodox/conservative Episcopalians make is to believe (a) that Foggy Frank is speaking in good faith; or (b) anything he says.
