Four years ago I did a column marking the feast days of two of the church’s most important saints: Charles Borromeo (1538-84; feast day, Nov. 4) and Leo the Great (pope from 440 to 461; feast day, Nov. 10).
Leo was still only a deacon when elected to succeed Pope Sixtus III. Indeed, he was not even present at the conclave that chose him, having been away from Rome on a diplomatic mission.
As pope, Leo became a strong advocate of papal authority, but he himself was not interested in power for power’s sake. He used his authority to root out abuses in the church, to resolve disputes, to insure unity in pastoral practices, and to help clarify the church’s teaching about the divinity and humanity of Jesus Christ.
When another bishop, Hilary of Arles, presumed to exercise authority over neighboring French dioceses, Leo ordered Hilary to confine his pastoral activities to his own diocese.
