For the reasons given above the argument presented by the Bishop of Bangor in his letter is not convincing. He simply does not make out a convincing case for changing the Church’s teaching and practice.
Where he is right, however, is in saying that many people with same-sex attraction experience the Church as a hostile place. However, the proper way to address this is not to change the Church’s teaching.
As the Ed Shaw, himself same-sex attracted, argues in his important book The Plausibility Problem, the problem lies not with the Church holding that sex should only take place within heterosexual marriage, but with the way in which people within the Church collude with the culture in suggesting that you can’t be happy without sex, value marriage and family life above singleness, and wrongly identify godliness with heterosexuality.
What the Church needs to do, he argues, is recapture the importance of celibacy and singleness and provide a place where everyone is valued, loved and supported regardless of their sexual attraction. That is what is needed, not same-sex marriage.
