Answer
Answer:
A. believed they had complete power.
Brief Explanations:
Leaders of both churches thought they held full - authority. Western (Roman Catholic) and Eastern (Orthodox) church leaders had different views on power. The Western church claimed papal supremacy, while the Eastern church had its own understanding of ecclesiastical authority. They didn't have power over all European kings (B is wrong), they didn't think schism was unnecessary (led to the Great Schism in 1054, C is wrong), and the Western church generally did not allow priests to marry while the Eastern church had different rules on clergy marriage (D is wrong).
