I want to thank everyone. The responses were excellent.
Any Catholic of any of the 22 worldwide rites , Latin being the largest, can attend/receive communion freely in any “Catholic” Service (Mass/Divine Liturgy) here, throughout the world and at any time.
Catholics should attend an Orthodox Church if there is no Catholic Church within a reasonablle distance. This is so, because, though one might have the excuse of simply not attending . It is better to attend a vaild though separated sister Church service than nothing at all, expecially if staying over an extended period…than to not attend or recieve the Holy Eucharist at all. Keeping in mind that they are still separated brethren, and though they maintain a valid priesthood and Eucharist some of what they profess many not me in line with the fullness of the truth found in union with the Primacy of Peter.
PS: Matt the Catholic Church gives all its rites and churches equal standing Latin, Byzantine, Coptic or other no more than any other. See CCC 1200-1203.
1203 Specifically states:
"The liturgical traditions or rites presently in use in the Church are the Latin (principally the Roman rite, but also the rites of certain local churches, such as the Ambrosian rite, or those of certain religious orders) and the Byzantine, Alexandrian or Coptic, Syriac, Armenian, Maronite and Chaldean rites. In “faithful obedience to tradition, the sacred Council declares that Holy Mother Church holds all lawfully recognized rites** to be of equal right and dignity**, and that she wishes to preserve them in the future and to foster them in every way.”
