This is where the Archbishop of Canterbury & the rest of the Communion Primates could have a profound effect & they need to act SOON! If the ABC & the rest of the Anglican Communion says that TEC has abandoned the Communion & then recognize the Anglican Communion Network & it's partners as the authentic Anglican Church in the U.S., I think it would cause the Denis Canon to be invalid & unenforceable by the civil courts. You see, the Denis Canon says that the dioceses hold the property in trust for the National Church. If TEC is no longer the National Church in the eyes of the rest of the Anglican Communion, neither the TEC nor their diocesans should not be able to lay claim to parish property, assets, or endowments.
Of course, I've been told that I know just enough about the law to get myself into trouble...but I still think there's certainly nothing to lose & everything to gain if the ABC & Primates would only act decisively to toss TEC out on it's ear & recognize some other entity as the provincial See in the U.S.
May the Lord hear and grant your petition, and that right swiftly. My intercession is for the Bride of Christ to be rescued by Her husband from the clutches of the apostates.
