I'm a little late to this topic, but wanted to share my thoughts.
As far as the Antiochian Western Rite is concerned, we still abide by the succinct definition given by our first Vicar General, Fr. Paul Schneirla:“Western Orthodoxy is the rediscovery of the Orthodoxy which withered in the west, and its revitalization, not through the transferral of eastern Patristic thought and devotional attitudes, but by the patient searching out, assembly and coordination of the supratemporal factors which created and characterized pre-schismatic occidental Christianity in its essence, and the careful selection of valid survivals in contemporary western thought and culture. These supratemporal factors entail not just a rediscovery of liturgical practices but an appreciation of western Patristic thought, incipient devotional attitudes, practices and spirituality as they have evolved over the course of centuries.”
I believe that is exactly what the OP said they were looking for. Antioch's approach has been to reintegrate the Western tradition with Orthodoxy, preserving that which remains consonant with our faith, and purging anything that does not. It's really quite simple. It ensures the rite remains authentically Western and it ensures our Orthodoxy. It was never about recreating the past.
This vision is articulated quite clearly in our most recent Ordo, published by the Vicariate. There is an entire section titled "Fidelity to the Rite" which states:"Western Rite clergy are not to use the dress, vestments, rites, forms, or customs of the Byzantine Rite clergy at any time. Temporary exceptions are granted for us for specific services when serving with or for Byzantine clergy in a Byzantine service. An exception to the prohibition of Eastern customs shall be made for the cult of icons. In the use of icons in the church, home, and among the faithful, preference should be given to those of our Lord, the Theotokos (the Blessed Virgin Mary), major Catholic Saints and great feasts rather than to those of local Eastern Saints."
So, yes, when the guidelines provided for us are followed closely, the Western Rite is more than merely the liturgy, but is the entire traditional Western catholic way of life, purged and set within the living tradition of the undivided Church once again. Our calendar, vestments, music, chant, prayers, devotions, customs, gestures, fasting rules, are all thoroughly, wholly, and authentically Western.
That being said, if Orthodoxy is the Church, and I am a convert to that Church in a Western Rite parish, then I shouldn’t feel uneasy about being formed by the literature and theological teachings of modern Orthodox saints, fathers, and writers, even if they are Greek speakers or Russian speakers who worship according to the Constantinopolitan Rite. At some point we just have to move on and simply be Orthodox.
Sometimes we're so self-conscious
