“For me, the only important question is: What exactly do we mean by conversion to Orthodoxy? The following definition will, I presume, be acceptable to everybody: it is the individual or the corporate acceptance of the Orthodox faith and the integration in the life of the Church, in the full communion of faith and love. If this definition is correct, we must ask: can the “conversion” of a group or a parish, for which its spiritual leaders have signed a formal doctrinal statement and which has retained its Western rite, however purified or amended, can such a “conversion” – in our present situation, i.e., in the whole context of the Orthodox Church as she exists in America today – be considered as a true conversion? Personally, I doubt it very much. And I consider this growing interpretation of conversion in terms of a mere jurisdictional belonging to some Orthodox Diocese, of a “mimimum” of doctrinal and liturgical requirements and of an almost mechanical understanding of the “Apostolic Succession” as a very real danger to Orthodoxy. This means the replacement of Orthodoxy of “content” by Orthodoxy of “form”, which certainly is not an Orthodox idea. For we believe that Orthodoxy is, above all, faith that one must live, in which one grows, a communion, a “way of life” into which one is more and more deeply integrated. And now, whether we want it or not, this living faith, this organic spirit and vision of Orthodoxy is being preserved and conveyed to us mainly if not uniquely, by the Orthodox worship. In our state of national divisions, of theological weakness, in the lack of living spiritual and monastic centers, of unpreparedness of our clergy and laity for more articulate doctrinal and spiritual teaching, of absence of a real canonical and pastoral care on the part of the various jurisdictional centers, what holds the Orthodox Church together, assures its real continuity with tradition and gives the hope of a revival is precisely the liturgical tradition. It is a unique synthesis of the doctrinal, ethical and canonical teachings of Orthodoxy and I do not see how a real integration into the Orthodox Church, a genuine communion of faith and life may be achieved without an integration in the Orthodox worship.”
“The Liturgy of St. John Chrysostom or the Easter Canon of St. John of Damascus, are, I believe, much closer to that common and Catholic language of the Church than anything else in any Christian tradition. And I cannot think of any word or phrase in these services that would be “foreign” to a Western Christian and would not be capable of expressing his faith and his experience, if the latter would be genuinely Orthodox”
" I think that in the present situation of the Orthodox Church in America, the Western Rite, theoretically justified and acceptable as it is, would, instead of “facilitating conversion”, dangerously multiply spiritual adventures of which we had too many in the past, and which can but hinder the real progress of Orthodoxy in the West."
These quotes are from back in 1958 when Fr. Schmemann was voicing his concern to the Antiochian Archdiocese for then beginning in earnest the promotion of the “Western Rite”. I find his comments very sensible.
