Before the split in 1054, how did the Eastern Church and the Western Church view the Pope differently? The Eastern Church recognized the Pope's complete power. The Western Church saw the Pope only as a governmental leader. The Eastern Church completely rejected the Pope's power. The Western Church saw the Pope only as a religious leader

One of the reasons for the schism (this is how the split is most usually called) is the disagreement over whether the Bishop of Rome (as the Western Church though) was superior to the other bishops or equal to them (as the bishops of th East thought)

so the correct answer is The Eastern Church completely rejected the Pope’s power. - where you can understand that what is means it the power of the Pope over them.
