The main difference between the Orthodox churches and the Catholic Church is the issue of authority. Most all of the doctrines and all of the sacraments and devotions you know are also present in the Catholic Faith, especially in the Catholic Eastern rites. If you wish to convert, it is best to approach the local Catholic parish priest and declare your desire to do so as well as express which rite you wish to belong to. You will probably only need to make a declaration of Faith and express your recognition of the pope as the vicar of Christ. It should really be that simple.
I'm not sure about the Greek Orthodox's Church perspective, but the divorced Roman Catholic woman is still technically in the sacrament of marriage with the man, until it is nullified by the Catholic Church.
Greek Orthodox.
I assume you mean Roman Catholic. If so, then: No, Greece is largely Greek Orthodox. As an anglo-catholic I believe that Orthodox Christians are members of a valid branch of the one, holy catholic and apostolic church. But they are not roman catholic.
Roman Catholic AnswerThe Catholic would need to apply to his priest for an annulment, I don't know what the regulations are for the Orthodox.
christian but not catholicANSWER 2Two religions have orthodox branches: Jewish Orthodox and Greek Orthodox Catholics (as compared with Roman Catholic).
A:You are what you wish to be. Your own personal religious beliefs can only be decided by you, so you could choose to be Roman Catholic, Greek Orthodox, or indeed not hold any religious commitment at all. It is entirely up to you..Catholic AnswerYou follow the rite of either parent, most likely the rite in which you were baptized. However, the Orthodox Churches are not technically separate rites, they are in schism. If you mother is Catholic, and you were baptized in the Catholic Church, then you follow whatever rite that she is. If you baptized in the Greek Orthodox Church, your baptism is valid, but you need to convert, so you need to speak with a priest.
Since you are confirmed Orthodox and married a Greek Orthodox, the Orthodox Church requires that any children you may have should be baptized Orthodox. Also, as an Orthodox, you are not allowed to baptize your nephew or any other person in a catholic church. From the Catholic point of view, unless your nephew is to be reared a Catholic, he may not be baptized in the Catholic Church. If he is to be reared Catholic, either by his parents or godparents, the Church will receive him. No you are GREEK orthodox u must not I reapeat not baptisma your child at a catholic church.
If the penitent (the one confessing) is Greek Orthodox, not in full communion with Rome, he is welcome to confess to a Catholic priest, either a Roman/Latin one or a "Greek" or "Byzantine" Catholic. He is also permitted by the Catholic Church to receive any of the other Sacraments/Mysteries in our churches, without this indicating in any way a wish to become Catholic. However, his own jurisdiction may not permit this (it can even be excommunicable depending on jurisdictions), so he should check with his own parish priest, spiritual Father or bishop. Usually the Orthodox bishops only permit it in cases where there is no Orthodox parish or mission accessible to the Christian in question.If by 'Greek Orthodox Catholic' we mean someone who is a Byzantine-rite Catholic following Greek traditions but already in full communion with Rome, then he can also receive any of the Sacraments in any Catholic Church. It's not an issue..Catholic AnswerAs noted in the answer above, your question is a little confused as there are Greek Orthodox Christians and there are Greek Catholic Christians, they both follow an identical Rite, while the first in not in communion with the Pope, and the second is. If by "Greek Orthodox Catholic" you are referring to an Greek Orthodox Christian, then, WITH THE LOCAL BISHOP'S PERMISSION, the Greek Orthodox may receive confession and Holy Communion if he is in immediate danger of death and is unable to get to a priest of his own communion. Under any other circumstances, he would be required to convert first. A Greek Catholic Christian is already Catholic and is required to receive Holy Communion and confession regularly from a Catholic priest. Please note that there is no such thing as a "Roman Catholic priest" unless you are speaking of a Catholic priest in the diocese of Rome: It's just Catholic, not Roman Catholic. Roman is an epithet first commonly used in England after the protestant revolt to describe the Catholic Church. It is never used by the official Catholic Church.
If you are asking, "Do Greek Orthodox people marry Catholic people?" the answer would have to be, "Sometimes they do." Probably the easiest to recall instance of a Greek Orthodox person marrying a Roman Catholic person is the marriage of Jacqueline Bouvier Kennedy to Aristotle Onassis.
Today most of Italy is Roman Catholic and Greece is mostly Greek Orthodox.
Catholic AnswerThis is known in the Catholic Church as apostasy and is an automatic excommunication. If there is something you feel drawn to in the Greek Orthodox Church, then you should look into the Greek Uniate Church with is the part of the Greek Church which has always been in union with Rome (even after the Greek Orthodox left the Church). You may attend Greek Uniate Sacraments with no special permission, but to officially change Rites, you would need to apply to your Bishop and their Bishop.
That would be "Roman Catholicism". It is a Christian religion that believes in the Holy Trinity of God, Jesus, and the Holy Spirit. There are other type of Catholic churches, like the Greek Orthodox or the Russian Orthodox.
