Can anyone summarize real quick what happened in the split between the Eastern Orthodox and Catholic Churches?

In the 11Th Century a group of Catholic clergy rejected the God-given authority of the Vicar of Christ, the Pope, who alone holds the keys to the Kingdom, thereby placing themselves in schism from the true Church. This group of clergy and their followers became the first Orthodox Church.

take Paul's word for it. he got it right on.

The Orthodox and Catholic Churches were one and the same until they separated from one another in 1054 mainly over the role of the Pope.

There are very few theological differences. The main difference is that the Orthodox Churches (http://www.newadvent.org/cathen/11329a.htm) use the Byzantine Rite (http://www.newadvent.org/cathen/04312d.htm) and the Catholic Church use the Roman or Latin Rite.

Another difference is the Filioque clause in the Nicene Creed, the original which the Orthodox follow is
"And in the Holy Spirit, the Lord, and giver of life, who proceeds from the Father."
And the Catholic revision is:
And in the Holy Spirit, the Lord, and giver of life, who proceeds from the Father and the Son."

Pope John Paul II said of the Orthodox Churches in Orientale Lumen, "A particularly close link already binds us. We have almost everything in common."

With love in Christ.

Majority of the Christian Bishops did not accept the Bishop's of Rome claims to have the authority over whole Church.
