I found a 2017 interview in French with Bishop Mark of the ROCOR-MP on the occasion of the 10th anniversary of the capitulation to Moscow. The article is in the ecumenism section of the papist diocese of Paris. In the introduction to the interview, Bishop Tikhon (Shekhunov) explicitly frames the union of 2007 as the "reunion" of the two "branches" of the Russian Orthodox Church. Not surprisingly, OrthodoxWiki [sic] describes the event in precisely the same terms:
"The Act of Canonical Communion with the Moscow Patriarchate reunited the two branches of the Russian Orthodox Church: the Russian Orthodox Church Outside Russia (ROCOR) and the Moscow Patriarchate."
This sort of spin is interesting in light of ROCOR's anathema of 1983, which of course specifically rejected the branch theory. I was aware of the "two paths" explanation for the union, but "two branches"? Really? It appears that the branch theory is normative in World Orthodoxy.
I will translate the interview when I find time. In the meantime here are the links:
