They are shall we say about 85% in synch with each other. Russian and Greek Orthodoxy worship the same God, honor the same ( generally) saints, and have an elaborate system of rituals and sacraments- numbering 7 major sacraments. The ORTHO Rites differ in the following. They do not recognize the primacy or supremacy of the Pope, there is loosely more latitude for such things as divorce. There are differences in worship apart from the obvious language angles- for example the (Three times around the Horn) practice (l080 degrees of arc, By the way) which is a Wedding protocol in Russian and Greek Ortho use but has no counterpart in the Roman Catholic church. Statues are not used in Ortho churches but two-dimensional Icons, also spelled Ikons are. Communion is frequently under both kinds- Bread and wine. Finally one major difference is priests or ministers are permitted to be married- (only once) if a minister"s wife dies he cannot remarry) but Bishops are requiired to be celibate and the higher-ups are only selected, so to speak from the (Regular- celibacy-bound clergy). There are different ecceleasiatical ranks such as Metropolitan- a sort of Urban Bishop-like officer. No Stacy, he does not wear a subway-conductor"s flat-top hat! That"s an old joke, lilke those about De Gaulle and the IRT. Kidding aside the two faiths have a lot in common and stately, formal ritual is a mark of the Orthodox faith, no frivolous folk-hymsn unless handled by the choirs.
They are both the same. Although there are some branches of Catholicism that have to do with what cultures involve into their religious traditioins, like eastern rite catholics, byzantine catholics, but the main catholic is Roman catholic and that is the best one to be in. The entire Catholic church though, with all the branches, makes up one big Church, the mystical body of Christ.
The meaning is the same.They are synonyms (lolz!).There is no difference between these two terms. It is refered to as Roman Catholicism because the center of this religion is in Rome and it also existed first in the Roman Empire.It is the same you only add the word Roman at the beginning. But sometimes, this makes some confusion because some think that a Roman Catholic is a Catholic from Rome. A Catholic, one who believes in Catholicism wherever he or she is or from can also be refered as a Roman Catholic.I am a Roman Catholic from the Philippines. Got it? :) Pax Tecum!
Roman Catholic Answer
Below are the definitions for both words from the Catholic Dictionary

Catholic
from A Catholic Dictionary, edited by Donald Attwater, Second edition, revised 1957
I. The word is derived from Greek and simply means universal. In combination with the word "church" it essentially merely indicates one of the marks of the Church, and was so used by St. Ignatius at the beginning of the 2nd century; but in the course of history it has come to be the distinguishing epithet of the Church of Christ and his faith: under other circumstances its place might have been taken by "apostolic" or "one." The use of the word in this distinguishing way became current and common in England only from the middle of the 16th century. In some mediaeval translations of the Creed unam sanctam catholicam et apostolicam ecclesiam is rendered "one holy apostolic church general."
ii. A Catholic is any person who, having been baptized, does not adhere to a non-Catholic religion or perform any act with the intention or effect of excluding himself from the Church. A "good Catholic" is one who practises his religion to the best of his ability.
iii. Catholics normally call themselves Catholics without qualification, and are distinguished by the name alike in West and East; except for a body of High Anglicans, no other Christians use the name as a distinguishing title. But Catholics of the Byzantine rite sometimes calls themselves Greek Catholics, Chaldeans are so called, and Maronites always refer to themselves simply as Maronites - they avoid the name Catholic for the good reason that there is no such thing as a Maronite who is not a Catholic, and because in Syria the epithet particularly designates a Catholic Melkite.
iv. As an adjective, Catholic in this special sense should only be used of subjects of which Catholicity is predicable, e.g., a man as man, a church, building, or catechism. To speak of a Catholic artist or grocer, Catholic poetry or truth is inaccurate and misleading: an artist or grocer who is a Catholic is a Catholic as a man (and this without reference to whether he paints only ecclesiastical pictures or supplies cheese only to the clergy); poetry may deal with a Catholic theme or be written by a poet who is a Catholic, but is not by that fact anything but poetry; truth is truth and it is improper to call the truth about the Catholic Church, Catholic truth; (cf., Catholic arithmetic, a Wesleyan judge, Quaker music, and, particularly, Catholic culture).
Roman Catholic
A name used by many English-speaking non-Catholics for members of the Catholic Church, as a qualification of their exclusive right to be called Catholic, of whatever rite, looks to Rome as the centre of the Church and the seat of her supreme pontiff and head, the expression in itself is unobjectionable and is in fact sometimes employed by them, especially in certain countries of Europe. But its use by Catholics is unnecessary and, having regard to its connotation for many non-Catholics, sometimes to be avoided.
Both are generally the same. In fact, from when Christianity arose to around 1053, there was one sect of Christianity. At 1053, due to differentiating views, Eastern Christianity and Western Christianity split. This is called the Schism of the East.
Today, they share, for the most part, similar rites. The only MAJOR difference: the authority! Western (Roman) Christianity, for the most part, believes that it is the pope who is God's communicator with the mortal world. Eastern (Orthodox) Christianity, for the most part, believes that is the patriarch who is the moral and political leader of the Byzantine Empire (now long gone).
The patriarch, for the most part, still exists today...in a predominantly Muslim country! His name is the Ecumenical Patriarch Bartholomew I.

Russian Orthodoxy is not part of the Catholic religion. I don't know the exact time or history, but Catholicism came about once it broke away from Orthodoxy. Hence, Catholicism is the first religion to break away from Orthodoxy. Historically, Orthodoxy is the first established Christian religion, Catholics upon breaking away, became the 2nd Christian religion.

Catholicism. They make up their own rules as they go along.
I assume you mean the official split into Eastern Orthodoxy and Roman Catholicism, which happened in 1054.
W. A. Visser 'T Hooft has written: 'Anglo-Catholicism and orthodoxy'
The Greek Orthodox Church is one of the oldest Christian traditions, tracing its roots back to the early Christian communities in Byzantium in the first century AD. It officially became separate from the Roman Catholic Church in 1054 with the Great Schism.
