Explain the argument between the Eastern Orthodox Church and the Roman Cathlic Church

I really need help because I have a huge question tomorrow and this is the only question that I don't know please help me.

The issue was: Did the Holy Spirit "proceed" from the Father alone or from the Father and the Son (foliage clause)? Never been resolved.

Rather than try to find information from people who will either ignore your question, give you a line of trash as an answer, or flat-out lie to you, may I suggest you go ogle for "Great Schism" or schism of 1054 or other things. There are several differences between Catholic and Orthodox adherents:

Orthodox priests may marry; Catholic clergy cannot (there was a papal decree back in the middle ages that prohibited priests, monks, and nuns from marrying).

The Orthodox do not believe that the Host or wafer or piece of unleavened bread becomes or transforms into the real body and blood of Christ. This, however, is one of the Catholic Church's cardinal doctrines.

Orthodox adherents do not acknowledge the Pope as head of their church; Catholics, clearly, do so.

Catholics have seven sacraments; the Orthodox do not, as I understand it, have more than 2 or 3.

Up until recently, Catholics were not officially permitted to read the Bible for themselves--this has changed in the last several years. The Orthodox do not seem to share this view but that's something where I don't recall all the details. Some of that may depend on which branch of Orthodoxy--Brother Andrew of Open Doors tells of a team who visited a certain country, then under communist rule. They heard that a new translation of the Bible was available and if they wanted to see it, then a visit could be arranged. The team members told how that they literally bumped into the priest when he stopped. The reason given was that no ordained person was permitted to stand closer than four yards (!) from the scriptures! You can read about that and other encounters in "God's Smuggler", available from Open Doors itself.

If you can find a church history textbook at the local library, or even at http://www.ccel.org then this might be able to help you. Just be sure to give credit where due when you give a source.

The most important point here is that it has not been resolved and the schism between the Churches still exists today.

The differences are many, too many to discuss here.

The prime arguments at the time of the Great Schism:
The Catholic Churches of the Eastern Roman Empire (now called the Eastern Orthodox Church) believed (and still believe), in continuity with the ancient church, that no single bishop ruled the others; decisions were made in councils; they also held to the council-defined Nice Creed that states the Holy Spirit proceeds from the Father.

The Catholic Church of the Western Roman Empire (now called the Roman Catholic Church) decided unilaterally that their chief bishop, the Pope of Rome, was also the chief bishop of the churches in other areas; the West also made an unauthorized change to the Creed to say that the Holy Spirit proceeds from the Father and the Son.

These issues have *not been resolved, and continue to divide Christianity.

Someone answered that the Orthodox do not believe the bread and wine become the body and blood of Christ. That is untrue. We do believe, as we state in our communion prayers "I believe that this is truly your pure body, and this is truly your precious blood." What we don't have is the theory of "trans substantiation", which attempts to define how the change is made. We simply affirm that the change *is made, and don't try to figure out how.

Blessings.
