Ummm... we don't agree with Anselm at all. Also, we believe that grace and presence come through the sacraments. Jesus truly is the bread and wine, that is not simply grace. Like it or not, Orthodox and Catholic are similar. The differences between us are nothing more than mysteries vs sacraments and patriarch vs pope. I can say that because many Orthodox churches have returned to the Catholic church. Why do you think Catholicism has an Eastern Rite. Right next to my parish is a Ukrainian church that recognizes Rome.
Those 'orthodox' who went with Rome were lied to by many Jesuits who said the pope is Orthodox now and so many even to this day in the Ukranine and Poland say they are 'orthodox under Rome'
I am a Traditional Orthodox Catholic Christian of the Western Rite. Rome has departed from the Faith thus Protestantism and ecumenism and modernism have arisen in the West
And no our patriarchs (if there were any) are not in any power of 'universal authority like your pope who confesses ecumenism and modernism.
