The fact is that the duplicity on the Anglican side was at a remove from direct contacts with the Orthodox, and probably involved deception (or perhaps self-deception) of the Anglican party, Bishop Grafton of Fond du Lac.
It seems fairly clear that Bishop Grafton, a leading American Oxford Movement type, personally held a faith more-or-less identical to the Orthodox, and was genuinely interested in union. The problem is that the rest of the PECUSA House of Bishops (with perhaps one or two exceptions) were only interested in getting an Orthodox nod for the validity of Anglican orders as a point in their polemics with Rome.
However much the Evil One acted in the Anglican duplicity at that time, and however much the Evil One has lead American Anglicanism further from the truth so that it is no reasonable to speak of apostacy rather than mere heresy, the Spirit was active in those dialogs: the way for many, many former Anglo-Catholic clergy and laity to escape from the Anglican apostacy back into the bosom of the One Holy Catholic and Apostolic Church was prepared in the discussions between Bp. Grafton and St. Tikhon.
The Anglo-Catholics should have left the Church many years ago. I am happy to be involved in the Evangelical wing of the Anglican Communion and we maintain the original Protestant Theology of the Anglican Church and the original "Protestant Episcopal Church in the United States of America".
I agree with you that the ECUSA has been reduced to a hopelessly Apostate and even Pagan organization.
