Ahem...it was relegated back in the '70's to the status of "historical documents" by the same folks who gave us: female priests & bishops, a watered-down & unscriptural Book of Common Prayer, the practice of Mysticism (including, but not limited to: Druidry, walking the labyrinth, Taize music, Women's "Eucharists" & Buddhist prayer beads on which they've hung a cross & remarketed as "Episcopal" prayer beads). Shall I go on? Let see...abortion, co-habitation, out-of-wedlock pregnancy, unlimited divorce & remarriage, non-celibate homosexual clergy, and same-sex "marriages." All these things are A-OK in the "new & improved Episcopal Church" - thanks to these enlightened, progressive thinkers who decided 30 years ago that the 39 Articles of Religion should be relegated to the status of historical footnotes. Bah!
The loony left was doing its best to water down the scriptural basis for the prayerbook, remove all negative references to homosexuality from the Lectionary, etc. etc.
But meanwhile, the Anglo-Catholic wing was trying to (1) bring the Eucharist into prominence instead of Morning Prayer with communion every fourth Sunday and (2) bring the rite closer to the Roman Rite.
The mess that they got is what happens when you try to deal with the devil.
Which is one of the reasons why we are now Catholics, but that's another whole story . . .
