I don’t disagree with any of your excellent exposition of history, but even John Wesley claimed his Episcopalian identity on his death bed, if I remember right.
There is no "but even" there. He didn't leave Anglicanism; it pushed him out. Just as Luther, an Augustinian monk, was excommunicated from the Roman Catholic Church for trying to reform it when the scandal of selling indulgences was taking place, Wesley was ejected from the Anglican establishment for breaking the class system in England and opening the gospel to "the unwashed" laborers and social outcasts. Methodist Episcopalianism was also powerfully supportive of temperance movements, long before there was an A.A.—communion was unfermented grape juice, no alcohol. The liturgy of the Methodist Episcopal church I was raised in was very much like that of the old-time Episcopal (Anglican) Church. All that changed in the late 60s.
