It is not the formal teaching of ECUSA, anywhere (I would hope). I thought I would go to the 39 Articles of Religion, but many of them contradict this notion of universal salvation in one way or another. There do seem to be those who are saying this, however. And they're looking ever more likely to end up on the outside of the worldwide Anglican Communion, when the slow Anglican process comes to an end. (I note
here that some alliances and reunifications are occurring in the Continuum, with some expectation that "The Day" is coming, the day when ECUSA is ousted and they can become the "Third Province".)
Thanks. I may have asked this before, but do think that I am using the word "communion" differently than you or for that matter the ECUSA revisionists? The uproar over the fact that the African Archbishops would not attend at a Liturgy with Griswold, which to me seems quite canonical, indicates to me that at least insofar as the revisionists are concerned, we are speaking of different things when we speak of communion.
