Today's Wall Street Journal has an interesting and instructive review of church schism, prompted by recent doings in the Episcopal church-- Their Separate Ways by Philip Jenkins, author of The Lost History of Christianity. (This week the ECUSA's triennial convention ended the ban on gay candidates serving in ordained ministry. Meanwhile, earlier this summer conservatives organized a rival church, the Anglican Church in North America, and essentially withdrew.)
Jenkins gives a good brief summary of the history of schisms in the church--some successful, some not so much, and some failures. Presbyterians, like Episcopalians, were born in schism from the Roman Catholic Church. Is it really surprising that churches born of schism continue to be subject to schism?
