If (or when?) the world wide Anglican Communion fully cuts communion with TEC, then of course Minns will recognized as a rightful bishop in Virginia. An apostate Church is no longer a Church at all...and it's bishops will be considered to have vacated their offices, regardless of whether TEC as a denomination goes on or not.
Correct me if I'm wrong, but AMiA's American bishops were consecrated AFTER the formation of the AMiA....whereas Martyn was consecrated, and unchallenged in that consecration, before (or simultaneously) as the formation of CANA. Therefore Minns is ALREADY recognized as a Bishop.
No more than the AMiA bishops, who were also consecrated by Global South archbishops.
I've heard the CANA situation described as a move by Peter Akinola to help move the center of Anglicanism to Nigeria ... not coincidentally under his control. In many ways, it reminds one of the the Constantinople vs. Rome split.
