Saint Leo the Great, Pope and Doctor of the Church
St. Leo the Great, elected in 440 as Pope, worked tirelessly as “Peter’s successor,” guiding his fellow bishops as “equals in the episcopacy and infirmities.”
St. Leo’s work branched into areas indicative of his notion of the pope’s total responsibility for the flock of Christ. He worked at length to control the heresies of Pelagianism—overemphasizing human freedom—Manichaeism—seeing everything material as evil—and others, placing demands on their followers so as to secure true Christian beliefs.
During the pontificate of St. Leo I (d. 461), the Ecumenical Council of Chalcedon defined Jesus Christ as one divine Person with two natures: divine and human. St. Leo has written Epistola Dogmatica (the “Tome” of Leo) to Patriarch Flavian of Constantinople, which was read and assented to by the Council Fathers.
With strong faith, St. Leo also led the defense of Rome against barbarian attack, taking the role of peacemaker.
St. Leo died on November 10, 461. Pope Benedict XIV proclaimed him Doctor of the Church in 1754.
O God, who never allow the gates of hell
to prevail against your Church,
firmly founded on the apostolic rock,
grant her, we pray,
that through the intercession of Pope Saint Leo,
she may stand firm in your truth
and know the protection of lasting peace.
Through our Lord Jesus Christ, your Son,
who lives and reigns with you in the unity of the Holy Spirit,
one God, for ever and ever. Amen.
