Bishops turning up in another patriachate without permission is not good. I trust Patriarch Pavel sent a strong protest.
This kind of thing makes me all the more eager for the contra-canonical situation in North America to be fixed and for us to have our own Patriarchate. The world indeed imitates America, and unfortunately, it seems even some Orthodox bishops in traditionally Orthodox countries, who should know better, to want to emulate the ethnic separatism which had plagued the Church in America since the Bolshevik Revolution cut us off from Moscow and Patriarch Miletius (of sorrowful memory) seized the opportunity to poach territory with the establishement of the Greek Archdiocese.
We in America aren't spiritually mature enough to have our own Patriarchate -- the thought of us on our own without any moorings is a little frightening -- but we should all be under one structure, under the omophorion of an "old world" primate. My vote would be for either Moscow or the Church of Greece proper. Both are real churches with real dioceses and real experience in administering them. But we need to get to where there is only one bishop in each geographical area here in the US, with all Orthodox parishes in that area being ministered to and supervised by a single bishop. Most national churches in the history of the Orthodox Church who received autocephaly had been in existence far longer and were far more stable at the time of receiving autocephaly than our brief and tumultuous existence here.
