"From Duncan's perspective it doesn't make sense to include them in convocations that are geographically within the United States, so a new 'international' convocation is being created. This is not to overlook 'Common Cause' with the APA, the REC, and hopefully, other break-away Anglican flavored entities, and he clearly hopes that it will one day include the AMiA and perhaps even the Charismatic Episcopal Church (CEC)."
The last time I checked, the CEC wanted to eventually come into communion with Rome.
Is this no longer the case?
I've actually heard nothing from the CEC about this; are you thinking of the TAC, perhaps? My father once described the CEC as a group of Protestants (denomination forgotten) who discovered the Book of COmmon Prayer.
