Three causes of Great Schism:

There were points of doctrinal dispute (such as those I listed).  Ultimately, though, the biggest reason was the struggle over authority in the church.  In 1054 CE, there were mutual declarations of excommunication between the pope (in Rome) and the patriarch (in Constantinople) that  resulted in what is known as "The Great Schism" -- a monumental split between the western church (the Roman Catholic Church and what has become known as the Eastern Orthodox Church.   "Catholic" means universal -- the Roman pope was intent on asserting his leadership over all of Christendom.  "Orthodox" means "right teaching."  The Eastern patriarch and church were asserting their teachings to be right over against positions held in the West.  There were a number of doctrinal issues debated hotly between East and West over the centuries leading up to final break between the two halves of the church. But more than anything, the split came down to "church power" -- who held control over the church.
