B. Should the pope be supreme in church affairs?

Explanation:

One of the main reasons why the Eastern and the Western Church could not agree with each other was because of the confusion that surrounded the role of the Pope. The conflict between these two churches led to what is known as the East-West Schism, or the Great Schism. The Great Schism was the break between the Roman Catholic Church and the Eastern Orthodox Church. The schism was motivated by other important differences, such as the issues related to the place of the Holy Spirit, the use of leavened or unleavened bread and the place of the See of Constantinople.
