Actually, the OP would be covered by the Canon I cited, so she’s clear to attend the Greek Orthodox Church without needing to attend a Latin one (at least by my, and most other Eastern Catholic, interpretations). Remember, it’s not a denial of the Catholic Faith in any way, shape, or form./QUOTE]
Actually it is.
Please don’t confuse the Orthodox church with the Eastern Rite Catholic church just because they share a form of liturgy. They might look similar on the outside, but they are very different churches. In fact, many Orthodox scholars and theologians consider the Catholic and Protestant church to be more closely related than the Catholic and Orthodox church.
The Orthodox church does not accept any of the dogmatic pronouncements of the RC church after about 800 AD. But Catholics are required to believe them. We do not believe in the primacy or infallability of the Pope, the Immaculate conception, purgatory, and there are numerous others.
It is difficult to believe that for a RC to attend an Orthodox church would fulfill your Sunday obligation. Regular attendance would imply that you believed that the Orthodox teachings are true and would be an implicit ackowledgement that the RC church is in error. It is hard to see how this could ever fulfill your requirement to worship as a RC.
§2. Whenever necessity requires it or true spiritual advantage suggests it, and provided that danger of error or of indifferentism is avoided, the Christian faithful for whom it is physically or morally impossible to approach a Catholic minister are permitted to receive the sacraments of penance, Eucharist, and anointing of the sick from non-Catholic ministers in whose Churches these sacraments are valid.
The important thing here is it must be “physically or morally impossible to approach a Catholic minister”, and that isn’t the case here. It is a matter of convenience from what I can see.
Also, although the RC church “allows” you to go to the Orthodox for the sacraments it is forbidden by the Orthodox church. It is done sometimes for compelling reasons (if you’re dying, for example), but they are exceptions.
Nor would any Orthodox priest that I’ve ever met allow you to take communion in their Church because you decided it would be “better” for you to do so. In fact at every Liturgy I’ve attended where the priest knew that there were non-Orthodox present they always made an announcement before communion that it is only for baptised, chrismated orthodox who have prepared by fasting and confession.
It is the norm when attending an OC other then your home parish to introduce yourself to the priest before approaching for communion. Once while I was on vacation I ended up in the wrong line for communion by accident. Since that priest had no idea who I was he spent a few minutes grilling me. Luckily, one of the parishioners who knew me well came up and vouched for me. It was only then that the priest would commune me.
When I converted from the RCC to the OC it took me a year of study before I was allowed to join and at no time before I was admitted into the OC was I ever allowed to take communion. The priest said that if I was dying that he would give me the sacraments, but only then.
I hope that none of this offends you, that isn’t my desire. II just wanted you to understand the Orthodox position. Also you need to know that many Orthodox Christians (especially the Priests, Bishops etc) will have a much stricter view of what is allowed/proper than many of their RC counterparts.
