Virtue is claiming that the Archbishop of Canterbury's addressing ++Bob Pittsburgum as "Most Reverend" legitimates his primacy. I refer to the Ecumenical Patriarch as His All-Holiness. That doesn't mean I'm in communion with him.
Our best bet I think is to assume a similar stance toward the Anglican Church in North America as our sister church does to the Lutheran Church - Canada. We're happy to be in communion with them if they should want it.
