So the more conservative churches would welcome 'chaste' homosexuals? How will they enforce that?
Presumably they will preach the Christian ideal of chastity from their pulpits as one of the constituent elements of their normal Gospel witness, and those among the faithful who cannot accept this moral teaching will leave and those who accept it will strive to live by it.
Presumably those who accept the teaching but struggle with it in their lives will seek the counsel of their pastors to make positive changes in the way they live and will be encouraged and challenged to do the right thing.
