Matt,
Similarly to what you describe, in the area of Boston in which the Melkite Cathedral is situated, there are Antiochian Orthodox, Maronite, and Syriac Orthodox parishes. It is not uncommon that one will find priests from each of the churches at the wake of a prominent member of the Lebanese or Syrian communities - regardless of the parish to which he belongs, or the wake of a parishioner from one of the churches who has family in 2, 3, or even all 4 parishes.
When Patriarch Gregory last came to Boston, the pastor of the Syriac Orthodox parish was waiting at the Eparchial residence on the Patriarch’s arrival there from the airport and was the first to pay honor to him.
A couple weeks ago, when we celebrated St Barbara’s Feast with the traditional ceremonies, followed by a hufle, one could readily have found a clergyman of whichever parish one desired, as all were seated together at one table in the Cathedral hall with Archbishop Cyril. This has been the way of the Eastern and Oriental communities in Boston for the past four decades, in my experience, and long before that. In perusing a 1942 program booklet, produced on the occasion of the Melkite parish celebrating its new temple, the advertisement section was replete with warm messages of congratulations and goodwill from the other Eastern and Oriental clergy, Catholic and Orthodox, in the area.
I believe that I’ve spoken previously about the situation in the early years of the 20th century, when a single church from one of the Middle Eastern Churches, Catholic or Orthodox, was often the only one of that ethnicity in a city or town for a period. Commonly, the parish would serve the pastoral needs of all the Arab Christians, until such time as their own priests became available. I had occasion to read an anniversary program from a Melkite parish in the mid-West which included congratulatory messages from two Orthodox parishes in the same city; both were phrased in warm terms and contained references to the Melkite parish as their “mother parish”. A reading of the parish history spoke of how their Orthodox brethren worshipped with the Melkites until priests of their own Church were assigned and how vesture, liturgical accoutrements, and even worship space were loaned for their use until the parishes became established.
I’m well aware that the history of relations between Slav Churches on either side of the fence was not always so rosy as this and I am thankful for the relationships that our Churches have had - but, I think the rancorous attitudes described are the exception rather than the norm in this day and age.
Many years,
Neil
