One reader asked a while back what my opinion is of the Western Orthodox experiment started some time about a decade ago. The truth is I have no opinion other than that the project is probably aimed at Anglicans and those in groups outside of communion with one of the ancient patriarchates. Liturgically they are quite scattered: there is a Hellenized "Liturgy of St Gregory" (Tridentine Mass with Greek bits popped in), the "Liturgy of St Tikhon" (Tridentine Mass with the anaphora of St John Chrysostom swapped for the Roman Canon), and a Hellenized Sarum rite. Some publishing house called St Hilarion Press also produces less Hellenized Sarum texts that I own and occasionally consult, although there are differences (no prayers for the pope, no filioque in the Creed). In America the Russians and the Antiochians were the primary movers. The project has generally stalled in the USA, although there is a Western Antiochian parish in Fort Worth, TX, ironically named St Peter's. I am acquainted with one former Episcopalian who became Orthodox via the "Western" path, but quickly switched to the mainstream Byzantine Orthodox setting.
If any readers have comments about the Western Orthodox endeavor or any experiences to share, they are more than welcome. I have little to contribute on the topic.
