CGW,
...and that Gregory's many jurisdiction changes are of no significance ...
I have researched Bishop Gregory's "jusrisdiction changes" very extensivly. I have read the letter he exchanged with Bishop Gabriel and Bishop Laurus regarding our synod, his opposition to ROCOR's communion with Cyprian, and have talked to people who know first hand about his relations while with the Lamians.
And as much as I might have a position with regard to certain matters both for and critically against him (and understand that he is a very vocal detractor of my synod) there is nothing I can see where he did not seem to act in a honest manner and was (at least) not completley without justification. And I might have some personal opinions that would indicate he made some ecclesiastical mistakes, but I can assure you, I have found nothing which seems to suggest he is not now an Orthodox bishop.
And the fact that he was ordained by the ROAC, one would also have to show the ROAC to not be Orthodox otherwise they are bordering on Donatism. Donatism of course says that the Grace of God cannot flow from a sinful bishop or even unworthy bishop despite them being part of the lawful Church.
