Alexander VI’s Papal Bull • Inter caetera was decidedly medieval in its concept of Papal power. It worked with the following syllogism: • All authority, spiritual and temporal, was given to Peter by Jesus, the Lord. • Peter’s successor in office, the Pope, inherited that authority. • The Pope by his own power can delegate that authority to others, which is what Alexander VI did when he delegated authority to the Spanish monarch, Ferdinand and Isabel and to their descendants.
