Here is one scenario for the future of TEC.
In 2020 its House of Bishops consists of 20% bishops in same-sex partnerships. This group, with counterparts in the House of Deputies makes a move to end "heterosexual privilege" in TEC through revision of the gender specific language of marriage services, and through modification of the role of Scripture (in which hetero-normativity is pervasive) in the life of the church. Hints of this future point of consideration were present in some talk I noticed at GC 2009 (but not in any actual resolutions passed), and is present in the address of one of the candidates for the Los Angeles episcopal election, mentioned in the post below.
Would the TEC GC in 2021 say "no" or "yes" to such a move? If it said "no", on what grounds would it do so? If (as I think likely) it said "yes", it would represent the seal on Bishop Gene Robinson's description of TEC as 'the gay church'. Would this seal be part of the growth or decline in numbers of members of TEC?
That last question is important. I suspect it has been considered by ++Rowan and the answer he has arrived at is "decline". He is simply too smart not to have worked out that the church which centres its identity around its gay and lesbian (and transgendered and bisexual) membership is a church with a fast shrinking membership as "hetero-normative" members peel away, or do not join as new members. Both in his own person, and as a responsible bishop, he cannot endorse the track TEC is on. When the Presiding Bishop of TEC does not understand the missional imperative of the gospel to convert people to Jesus Christ, ++Rowan knows that TEC is unlikely to grow through evangelism. He also knows that once Scripture is played fast and loose through revisionist reading (such as the episcopal candidate does in the link in the post below) it has no power to fuel the church. TEC's train is unlikely to crash. It will slowly come to a halt. Its track will have become a siding.
Far from "betraying" the partnered gay and lesbian clergy in the C of E, ++Rowan is doing them the great favour of working to ensure there is a viable church for them to belong to!
In love for TEC we must allow it the opportunity to take the course it is choosing without expelling or excommunicating it from the Communion (though also without the pretence that "full communion" and "participation" in all Communion events is possible).
I may be completely wrong. TEC's great experiment with a new ethic in which hetero-normativity is deconstructed may be a great success. I hope I live long enough to see which of ++Rowan's tracks proves to be the main trunk line. If it is TEC's track then I shall be the first to congratulate it.
