Got to wonder who in Moscow wrote this for the ROCOR crowd.
More likely the reverse. ROCOR is often to the right of the Moscow Patriarchate on controversial issues. In this case though my guess is that they are are just echoing criticisms that are gaining momentum. The Georgians, Bulgarians, at least some of the Serb and Greek hierarchy as well as the monks on Mt. Athos have all come out with serious criticisms of these documents.
