Basically, the Archbishop has asked the Episcopal rep to stay away from prominent gatherings of worldwide Anglican leaders, since the American denomination keeps doing the opposite of whatever agreements the global Communion works out.
The Episcopalian position grows more incoherent by the day - yesterday's denomination of intergalactic peace 'n' justice now crows about American exceptionalism and independence from foreigners. The "inclusive" church now dismisses the objections of "a few Africans."
The fragmentation of the Anglican Communion seems inevitable. The Episcopal Church has plenty of old money to cobble together an international "communion" of its own, built around gay (albeit closeted, in many cases) clergy in subsidized state churches of the Northern Hemisphere and small clusters of LGBT activists in the Southern. Won't be much in terms of congregations or Christian faith, but will get plenty of press as it issues proclamations and hangs its name on causes - especially those favored by opponents of Christianity.
Meanwhile, less moneyed but growing and spiritually vital Anglican Provinces have formed networks based on traditional Christian faith and appear ready to ignore the historic Canterbury connection altogether.
This isn't mere symbolism or reorganization. As Fr. Dan Martins points out,
...the church of Canterbury is a church that is not just old, but was itself established by a church that was founded by not one, but two, apostles: Ss Peter and Paul. Canterbury is the token of the apostolicity of my particular church. Being tied to Canterbury is not magic. It guarantees nothing in and of itself. But, as part of a system of connections and reference points, it is invaluable, and ought not to be tossed aside, even for reasons that, in the thick of present but ultimately passing conflict, appear weighty.
Anglicanism was an experiment in global Christianity based less on uniformity than on "bonds of affection" among people of Christian faith. But even bonds of affection can snap if the parties pull too hard in opposing directions.
Personally, it is at once heartbreaking and disgusting to have invested decades of ministry in a denomination that now betrays both Christian faith and the Anglican effort at global Christian fellowship and witness.
