I don't have much to add to the thread, other than a note about the relations between Serbia and ROCOR. While I don't think ROCOR and Serbia ever formally broke communion, nonetheless Pat. Pavle still spoke strongly against some of the activity of ROCOR. For example, around the year 2000 he reportedly said:
"Your Holiness knows the brotherly and Christian relations that the Serbian Orthodox Church and people had towards Metropolitan Anthony (Khrapovitsky) of Kiev and the bishops, monks and Russian people who came to us in flight from the violence of the communists in 1918. This brotherly relationship continued only until, after the fall of the communists, the representatives of the Russian Church Abroad started to spread their priesthood onto the territory of Russia, thereby violating the canonical authority of the Russian patriarchate. The Sacred Synod has more than once directed its protests to the leadership of the Russian Church Abroad in America and demanded that it cease from such actions since they are anticanonical and worthy of every condemnation."
(The source I found in a couple places for those statements is: “Information Bulletin” of the Department of External Ecclesiastical Relations of the Moscow Patriarchate, № 3, 2000, pp. 51-52)
