...the propriety of the Western Rites is another question altogether.Care to elaborate?
Whether or not it is/was a good idea to attempt to artificially ressurect a dead tradition, and if it was a good idea, if specific attempts have done so in a way that is particularly effective and/or faithful to the living Tradition remains an debated question within most local churches.
It's a broader question which would take this thread way off-topic--but I presume Fr. Anastasios did feel the need to add a caveat since some people seem to assume that if something is currently in Western Rite usage that means all Orthodox will find it acceptable. When, in point of fact, many Orthodox consider certain bishops/synod's decision to allow the Western rite in the same light that other Orthodox consider the decision to use the New Calendar or the decision of the Brezhnev-area MP to allow limited communion to stranded Roman Catholics.
