Reading through the various articles around the GAFCON formation and meeting, a number of them predicted an exodus of 1/4 to 1/3 of Anglicans from the Communion to form another Communion.
The number of those defecting would seem interesting - a sizeably minority versus a tiny fraction would be telling.
The problem is the “working within” crowd and the walking apart crowd. Many more, even in the USA, would come out if the orthodox majority would just take a definitive coming out stand. They should act more like “Baptists”.
