The doctrinal and moral peculiarities of the American Episcopal denomination constitute a marked departure from traditional Christian doctrine and moral standards.
The great majority of Anglicans are in Africa and India and find the support of homosexual marriage and practicing homosexual clergy (including the Bishop of New Hampshire) particularly abhorrent.
The Episcopal leadership and majority are not at all repentant.
In all probability they will slowly and painfully leave the Anglican Communion.
Those Episcopalians who wish to retain the central doctrine and moral practices of the Christian faith are slowly and painfully separating from the errant denomination.
The Roman Catholic service of excommunication which officially separates from the universal church and declares headed for perdition those who do not repent of heresy and scandalous behavior is judged appropriate for the Episcopal majority by one commentator (who says what many are thinking).
The physical parts of such ceremonies speak louder than words. The closing of the book, the ringing of the bell, the extinguishing and throwing down of the candle speak of final judgment and death, a preview of the Great White Throne, and the second death in the lake of fire.
