A wonderful report on a religiously complex area. Thank you for bringing so much of the complexity out by looking at the margins.
One small correction: the Ecumenical Patriarch is not the spiritual leader of the Russian Orthodox Church. The Patriarch of Moscow is the spiritual leader of the Russian Orthodox Church. Unless you mean "spiritual" to mean something besides the official, liturgical, and administrative head of the church, each patriarchate has its own spiritual leader. The patriarchs are considered equals, not leaders one of another.
