Buggery (and other sexual sin in the sado-masochistic vein) is an idolatry-of-hostility move. But it can be mighty addictive because we are all born sinners. The only real antidote for this is love of a divine quality. And that love can only be acquired through an embrace of Jesus.
The archbishop is right, ironically. “Jesus, we shouldn’t be here.”
