Hello Angel Gabriel!
I would highly recommend that you read “Orientale Lumen” as well as the Vatican II documents on the Eastern Catholic Churches and Ecumenism (especially the part pertaining to Orthodoxy). Ultimately, however, it must be kept in mind that these are Roman documents, expressed in Roman language. The Eastern Churches (whether Catholic or Orthodox) have a very different understanding not only of themselves, but even of Church unity than do their Roman Catholic brethren. This understanding is, sadly, often not respected by Roman Catholics (notice I do not say the Pope), and sometimes even by Eastern Catholics. Often if one goes about trying to elucidate and defend and Eastern understanding of the Church, unity, primacy, etc. to another Catholic you will be accused of being “Orthodox” or “schismatic.” I typically simply let it roll off my back and try to hold my tongue. I figure, if their hearts aren’t ready to receive a different perspective on the Church, then all my talking and arguing is going to do nothing to open their minds. I tend to talk too much anyhow.
You are right, however, in affirming that the Eastern Catholics are not “under” the Pope, but in communion with the Pope. As an Eastern Catholic I would say that we aren’t even “under” the Pope as the “universal pastor.” I’ve never seen the phrase “universal pastor” come up in any of the great theologians of the East that I’ve read (although I welcome correction if someone wants to provide me with Eastern sources). “Primacy” is a word that comes up. But what this primacy means is something that is still being worked out even within the Catholic Church. So to equate “primacy” with “universal pastor” isn’t necessarily accurate.
The best way that I’ve heard the role of the papacy described (especially with regards to relations with the Eastern Catholic and Orthodox Churches) is as the “older brother.” All the siblings (particular churches) can turn to their older brother for direction, guidance, to settle quarrels, etc. The older brother, however, doesn’t have the right to determine what each sibling will wear, where they will spend their time, etc. In other words, the older brother doesn’t have the right to micromanage the lives of his siblings (or when the get older, the families of his siblings). Now, if relations between siblings requires intervention in order to settle disputes, then the older brother has the right to step in. But this isn’t a right of power in the sense of dominating. It is a right, based in love, to serve the family by keeping peace and order. Perhaps I prefer this notion because of personal experience as an older brother.
