Question

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.

Answer 1

None of the four statements is accurate as written.

Before the 1054 schism the Eastern (Byzantine) churches accepted the Bishop of Rome as "first among equals" (primus inter pares) — they gave him honor and a leading role but rejected his claim to universal, direct jurisdiction over the whole Church. The Western (Latin) church, by contrast, increasingly claimed papal supremacy: the pope was seen as the supreme spiritual authority for all Christians (and exercised significant political influence as well).

If you must pick the closest choice from the four, option 4 ("The Western Church saw the Pope only as a religious leader.") is the least wrong — but it’s imperfect, because the Western view included claims of universal ecclesiastical authority and considerable temporal power, not "only" a religious role.
