Answer:
The major effect of the Great Schism was the creation of two separate churches: the Eastern Orthodox Church and the Roman Catholic Church, that had previously been unified under one church.
Explanation:
The Great Schism (1054) was the division of the Christian church into two: the Western (the Roman Catholic Church) and the Eastern (the Eastern Orthodox Church).
This breakup was the result of years of tensions arising from theological, doctrinal and political differences between them. For instance, while the Roman Catholic Church promoted using unleavened bread for the ceremony of communion and held that the pope (the spiritual leader in Rome) had authority over the patriarchs (religious leaders in the east), the Orthodox Church strongly disagreed with these practices and beliefs.
