Which term is used to describe the split of christianity that resulted in the catholic church and the eastern orthodox church

the great schism

Explanation:

the great schism is the term that is used. A schism is a division between people, usually belonging to an organization, movement, or religious denomination.

According to Roman Catholic canon law, a schismatic is a baptized person who, though continuing to call himself a Christian, refuses submission to the pope or fellowship with members of the church. Other churches have similarly defined schism juridically in terms of separation from their own communion.
