The late Fr John Meyendorff was indeed sharply criticized by the late Fr John Romanides for his proposal to align Varlaam with the nominalists and not with the Thomists. This does not mean that everything he wrote is no good: look at his _Byzantine Theology: Historical Trends and Doctrinal Themes_ (New York: Fordham University Press, 1974) and _Christ in Eastern Christian Thought_ (Washington: Corpus Books, 1969). It certainly does not mean that his descendents are to be categorized as incapable of writing good studies of this or other topics. Paul Meyendorff's book on the Nikonian 'reform' is indeed quite informative and judicious, and may be joined by an essay by the late Nicholas Uspensky, 'The Collision of Two Theologies in the Revision of Russian Liturgical Books in the Seventeenth Century,' included with two other articles by the same author in _Evening Worship in the Orthodox Church_, translated by Paul Lazor (Crestwood, New York: St Vladimir's Seminary Press, 1985). The first essay in this collection, 'Orthodox Vespers,' also contains material relevant to this topic.
That the Old Rite is fully Orthodox is now recognized all around. The Old Believers may indeed look like 'kooks' to outsiders, but the 17th-century 'reform' may also be regarded as a bit 'kooky'--it prevailed not on its merits but on the backing of the state with its coercive powers. When Peter the Great reduced the Church organizationally to a department of the government, there was no effective opposition because those who would have undertaken it were already outside of the Moscow Patriarchate; so the Patriarchate could be abolished and the Russian Church subjugated in an efficient manner. Solzhenitsyn is right about this: we should be repenting of the persecution of the Old Believers and not denouncing them. Yes, they have their foibles; who does not? _The Way of a Pilgrim_ proposes the correct course: let us restore a reasonably full typikon in our schedule of services, and respect for traditional standards of church order, and we shall then be in a position to discuss frankly with the Old Belivers the differences that separated us. The Pilgrim was right: they set a good example for the rest of us; not that we should copy them in every respect, but that we should attend to a full offering of the prescribed services performed in a proper manner.
