Primacy in matters of faith and morals?
Does the patriarch of Moscow believe in God? Patriarch, who is silent on the murders of thousands of innocent people. Patriarch whose spiritual children shelling of the largest nuclear power plant in Europe?
Is there anything human left (morality proper) in the president of an "Orthodox" country who is bombing children, women, the elderly; who creating the possibility of the greatest environmental catastrophe for the whole world?
This should be said ex cathedra in the main temple of the universal church no later than 12 o'clock at the time of Angelus.
And, yes, for such an event, Patriarch Bartholomew could be invited to co-celebrate. There are no more obstacles. The Anathemas of 1,000 years ago were denounced by their predecessors.
And this primacy is no longer a privilege, but a sacred duty of the Roman bishop!
