A long com-box debate on the Pope and the Orthodox
I’d have to do some studying to really keep up with this but it’s fairly obvious there’s been some kind of Roman primacy for a very long time at least as a man-made office like any patriarchate or other rank among bishops for the good order (bene esse) of the church. Both sides believe the episcopate is divinely instituted. As for Soloviev as quoted here, based on what little of him I’ve read I agree with him that the common Catholic faith of the two sides outweighs the differences but he was unfair to the Orthodox side.

HOU didst come to us without leaving Rome by the precious chains which thou didst wear. O first-enthroned of the Apostles, we bow down to them and pray: By thy prayers to God grant us great mercy.
