StAG is more evangelical than Anglican, I'd say, and the uk.r.c thread referred to an independent charismatic church, I think.

If the church does decide that committed gay relationships are OK, it will either called them marriages, or not. If it does, it'll change what "marriage" means, if not, it'll change the requirement that sex takes place only within marriage. Saying that the church cannot change either of these things is not useful: it's the church's choice.

mirroring God a la Gen 1:27

Are you a creationist, then?
