Oh dear, I’m going to have a preliminary bash at this while GKC catches up on his housework, or whatever it is he’s doing. It will be rather un-nuanced, and probably blatantly incorrect, but anyway GKC can put me right when he has time.
In the 70s a number of congregations in North America separated from the Episcopal Church, largely over questions of liturgy and also and especially the ordination of women. They claimed to be “continuing” traditional Anglicanism. That’s GKC’s mob.
Twenty or so years later there was a further load of separations, this time largely to do with social teaching, including attitudes to homosexuality. That lot included the congregations that came together as ACNA.
More have followed, here and there. PB Schori is even now reaching for the fire-lighters.
Shopping.
In a nutshell, yes.
Details found for the first part in DIVIDED WE STAND/Bess.
Tricky historical part was that, in the beginning around 1979, one of the first groupings of such Anglicans called themselves the Anglican Church in North America. A familiar name, currently. But totally different people.
Now off again.
GKC
I shall now move down to the air raid shelter in anticipation of GKC’s reaction to my ignorance.
