Depends on how you define always, I guess. Lol. Just look at the cruel homophobic pig (Justin Welby) who was in charge of the Anglican Communion until recently, when he had to step down because it turned out he had knowingly covered up for a sadistic child abuser.

I don't think there's any way to describe someone as homophobic and otherwise evil as him as progressive, and the Episcopal Church is of course part of the Anglican Communion. It was the same-sex spouses of Episcopal and Canadian Anglican bishops that Welby barred from the Lambeth Conference, after all. (Because, you know, Jesus refused to eat with people he thought of as sinners. Oh, wait ... Checking my New Testament. No, Jesus did the opposite of that. What do you know? Lol. Apparently Welby knew better than Jesus.)

Welby is obviously the opposite of a progressive, which he made abundantly clear after the conference by declaring at least twice that all gay people are sinners in the eyes of his church and always will be sinners.

But if we define mainline Protestants as only North American churches, and we set a cutoff date fairly recently (meaning within about the last century or so) I guess we can use the word always.

But I was raised Baptist, a church that emerged from a Calvinist tradition, and Baptists just LUV Calvin. I had his phrases sung up and down to me all my youth.

Imagine my shock in history classes in college learning what a monster he was.
