What struck me on first read was the appeal to chaos in the "Liturgical Principles" on p. 2 (good luck making heads or tails of some of this):
"Recognizing the varying notions of what makes public prayer recognizably Anglican, the task group identified these qualities..."
"Options must be provided so that this action of the entire Church - this common prayer - does not degenerate into a generic rite."
So, there is lots of "variance" and there must be "options" so that "common prayer" is not "generic."
But there are some certainties beyond question, according to the "Theological Principles" on p. 1:
"...these commitments become a blessing to the wider community. Blessing covenantal relationships, including [NPA note: but not limited to] same-gender unions, thus belongs to the mission of the Church in its ongoing witness to the good news of God-in-Christ [sic] and the Christian hope of union with God."
So although we can't agree on much of anything or expect much in the way of coherent expression of our faith, we are damned sure that God-in-Christ requires everybody in the Church to provide liturgies for all "household covenantal relationships." You don't think that's uniformity? Try becoming an Episcopal deacon, priest or bishop today if you disagree with it. Try getting elected to lay office in your diocese or the national denominational stuff if you oppose this.
The Bible, needless to say, has no authority in the matter. The document comes up with an interesting replacement for the traditional Prayer Book teaching that "the Holy Scriptures of the Old and New Testaments contain all things necessary to salvation." Now, church practices need only
"resonate with Scripture" (p. 2)
We have no common resources or understandings to which we can appeal. So where's this come from?
I think the clue is the constant capitalization of "Church" throughout the document. It can't possibly mean "the universal church" because the vast majority of Christian bodies would never affirm this document. So it means that The Episcopal Church now makes claim to the "one, true Church" moniker. Really creepy.
