For Russia, the situation involves both a dispute over canonical territory and a protest against the claims of Constantinople to be “first among equals” and have universal authority. The first is jurisdictional, the second a matter of the rule of faith.
If Constantinople decides to submit to Porshenko’s wishes and establish an Orthodox church on Ukrainian soil against the wishes of the canonical Church, is not the ecclesiological heresy of ethno-phyletism exactly what will appear? This denies the central Eucharistic mission of the Church.
The main problem is the claim of the Ecumenical Patriarchate that it is a source of order, life, orthodoxy…. whatever, for the rest of the Church. The claim seems to be that the Ecumenical Patriarch is somehow the essence and beginning of the Church in the way Adam is the beginning of the human race or the Father the source of the Trinity.
While not addressing the canonical implications of the historical documents surrounding the 1686 submission of Ukraine to Moscow, it emphasizes two much more fundamental and serious issues that he sees as present in this situation.
