“As for all those who pretend to confess the sound Orthodox Faith, but are in communion with people who hold a different opinion, if they are forewarned and still remain stubborn, you must not only not be in communion with them, but you must not even call them brothers.” +Basil the Great
“Guard yourselves from soul-destroying heresy, communion with which is alienation from Christ.” +Theodore the Studite
Perhaps most telling for the GAFCON hierarchs, since they apparently do not accept the dogmas of the 7th Ecumenical Council:
“He that saith not ‘Anathema’ to those in heresy, let him be anathema.” Declaration of the 7th Ecumenical Council
Seriously, it took a *long* time to come to a realization that 1) I was not likely ever returning to the wwAC, and 2) (even longer) that that's a good thing. My archbishop hears from me on the separation between the "Affirmation" churches.
