Why would someone down vote this comment when I am simply laying out an ecclesiological fact?
Eastern Orthodoxy is a religious system shot through with inconsistencies and nationalisms. A Latin Catholic would be rash and foolish to defect to Orthodoxy because he would have to abandon his culture and he would always be suspect as a foreigner amongst the Orthodox. And, of course, Orthodoxy is cut off from the true Church. Even to go to the Western Orthodox vicariates with the Russians or Antiochians is senseless since most Orthodox hold that only the Byzantine liturgy is acceptable worship.
What I stated in my comment is simply a presentation of facts and a counsel against rash judgments since the distance between Byzantine Catholics and Eastern Orthodox is much shorter than thd distance between Byzantine Catholics and Roman Catholics, yet the Byzantine Catholics are own brothers in ecclesial communion.
Not advocating taking up with them --- God forbid! --- but some Orthodox congregations, particularly Russian Orthodox ones, are very heavily made up of converts. Such people are typically not of nationalities one commonly associates with Orthodoxy. There is a certain deference to the culture and mentality of the "host country", whatever country that might be, but these people are not Russified (in the example I describes above) and never will be. This is in contrast to, most of all, the Greek Orthodox, whose parishes are, at the end of the day, pretty much Greek cultural and social organizations. Ditto the Antiochian Orthodox, though they are a bit (but only a bit) more able to comprehend someone being among them who is not Syrian or Lebanese.
Having married a Polish woman (albeit divorced for many years now) and having a son who is half of that blood and is a Polish citizen, I think of myself sometimes as what I call "SABA", "Slavic American By Assimilation". I could fit into a Russian or Ukrainian parish better than any other (somewhat of a familiarity with the language group, and I do like the food!), not to mention that I am sometimes taken for Slavic --- there is nothing about my appearance that suggests I'm not, whereas in a Greek or Lebanese parish, I'd stick out like a sore thumb. But I'm not about to become Orthodox, nor even Eastern Catholic for that matter. Latin Catholicism is my home and always will be.
