I agree with the comments other posters have made here, and Br. Nathaniel's status is confusing. On one hand, he is Orthodox, belongs to a canonical diocese, and is a Novice monk. He has the approval of two hierarchs, including the primate and that of his home diocese, for his campaign.
On the other hand, he is living in a diocese whose hierarch, the chancellor, officially opposes his campaign. Plus, he over-dresses for a monk, considering the white kobluk, which a Novice would not wear. His dress is showy, and Novices are not supposed to be.
He cannot be in weekly communion in his home diocese for distance reasons. Even if he is living as a hermit and has approval for that, can he still be said to be in regular communion with his home parish as he claims?
Obviously he is Orthodox, but he is not following the normal rules in the Church.
