Briefly explain the schism that occurred in the christian church in 1054. what controversy did it involve? what were some key differences in emphasis between the east & the west?

The Schism was the result of a prolonged period of tension and sometimes strangeness between the Latin and Greek Churches. In a nutshell, it was a power and influence dispute represented by the Pope and the Bishop.

Explanation:

The main cause of the Schism was the dispute over the authority of the Western Papacy to make decisions that affected the whole Church. Eastern Orthodoxy held that the primacy of the Patriarch of Rome (the Pope) was only of honor and that he had no authority to determine policies for other jurisdictions. Other catalysts included differences in liturgical practices and the Church's relationship with the Byzantine Christian emperor.
