Pope · Patristic

Pope St. Leo the Great

c. 400–461 · Roman theology of the papacy and the Incarnation

Doctor of the Church Latin

Doctor of the Church (declared 1754); pope 440–461.

Pope who turned Attila back from Rome, held the city together through the Vandal sack, and in his Tome to Flavian set out the doctrine of two complete natures in the one person of Christ, which the Council of Chalcedon (451) acclaimed: “Peter has spoken through Leo.” His sermons on the feasts and his letters assert with full clarity that Peter lives and judges in his successors.

Why he matters: He is the classic witness to the Petrine primacy as the Church understood it in the fifth century, and his Christological formula remains the Church's own; the Roman liturgy preserves prayers he composed.
