Dear brother Madaglan,
Thank you for the response. I hope my own reply is not taken by you as argumentative. If it gives you that impression, please forgive me.
Jesus Christ is sole head of the Church. That’s one truth.
Yes, that would seem to be a distinguishing factor (but why do non-Catholics love using that word “sola?”

). As a Catholic, I distinguish between the ultimate head of the Church, Who is Christ, and the temporal head of the Church, the Pope (if you ask the Pope who is his head…). As a Catholic, I would definitely not claim your statement (with the word “sole” in it) as a “Truth” because it denies several other Truths of the One, Holy, Catholic and Apostolic Church – namely, the biblical Truth that Christ has set someone over His household to feed them their spiritual food (Matthew 24 – most Catholics I think will go the Matthew 16 route, but I’m going with Matthew 24 J), the Truth of the hierarchical structure of the Church on earth, and the Truth of the Sacramental nature of the Church on earth, whereby Christ rules and cares for His Church through his temporal representatives (the denial of this is easily reflected in your apparent criticism of the idea that “there are not two heads, but one”), Truths which distinguish us from non-Apostolic Christians.
I mean, if I was in a room of Oriental Orthodox (i.e., everyone knew they were Orthodox), and someone asked another, “who is the head of your Church?” the other would answer with the name of their Patriarch or Catholicos. That’s because
it goes without saying that everyone (including the head bishops) acknowledges the ultimate headship of Christ. In a room full of Oriental Orthodox, the only one who would respond with a protest that “only Christ is the head of the Church,” ISTM, would be a Protestant.
The variety of rites is interesting, but the means and fact that many of the Eastern Churches have been divided from their respective Mother Churches and established in parallel jurisdictions to them, makes the situation more unfortunate than a boon for Catholicism.
The same can be said of the division between Coptic and Syrian EO and OO Christians. So this particular circumstance is not exactly a “plus” for Eastern Orthodoxy. Division hurts all the Churches, not just the Catholic Churches.
Concerning freedom to express their Faith, well perhaps but not really.
Just take the traditional Latin Catholic community as a recent example. For years following the liturgical overhaul in the Latin Church, all but a few elderly priests were forbidden to offer the traditional Mass (the later indults excepted, which were at the discretion of the local bishop). Millions of traditional-minded Catholics were effectively barred from worshiping according to the once ordinary now “extraordinary” form of the Latin Rite of the Church. Enforced celibacy on the Eastern Catholic Churches went against the tradition of the Eastern Churches to have married clergy.
The decision to switch to the NO was in the hands of the national Churches. I wouldn’t make the disobedience of traditional Latin Catholics to their bishops any sort of argument, unless you’re willing to make disobedience to bishops a selling point for Eastern Orthodoxy, which would not make it too attractive, IMHO. As far as enforced clerical celibacy, this was a very unfortunate local and temporary circumstance on a purely disciplinary matter that did not take long to begin to fix (still in the process of correction). In contrast, the Old Calendarist Schisms in EO’xy have taken a devilishly long time to begin to fix, which is rather telling, IMO.
Anyway, these disciplinary issues do not really touch upon what I intended in my statement about freedom to express the Faith according to the different Traditions. I’m talking about the fact that I can worship in the Catholic Church as a miaphysite, or that a Latin Catholic who believes in purgatorial fire can commune with an Eastern or Oriental Catholic who rejects such a belief, or that an Oriental or Latin Catholic with a theological Tradition focused on the Sacrifice and Atonement of Christ can commune with an Eastern Catholic with a theological Tradition focused more on the Resurrection of Christ, or that an Eastern or Oriental Catholic who believes in the Energies/Essence distinction can commune with the Latin Catholic who does not, or that a Chaldean Catholic of the ACOE Tradition can commune with an Oriental Catholic of the Coptic Tradition, etc, etc. I’m talking about issues much more relevant than disciplinary matters. And I’m not talking about the beliefs of your run-of-the-mill Catholic or Orthodox, but rather the official positions of the Churches. You simply can’t get that from the Orthodox Churches. The Catholic Churches have looked beyond theological formulations, and have been able to unite based on the Faith (once for all delivered to the Saints) that lies behind those distinctive theologies. EO apologists often accuse the Catholic Church of being too dogmatic and pharisaical. On the whole, however, the EO is either “just as bad” or much “worse,” ISTM.
Since becoming Orthodox, I have discovered a greater number of traditions in the Orthodox Churches than I would have expected, since I understood the Eastern Orthodox Churches to be simply Byzantine. Yet, the Russians, Greeks, Serbians, Romanians, Carpatho-Rusyns, Antiochians, etc. each have their own distinctiveness. And hey, the Orthodox have Western Rite Orthodoxy now, too!
We get all that and much more in the Catholic Church.
