Highlights

Main contribution
Leo gave the Council of Chalcedon a letter it could build on.
Primary source
Leo, Tomus ad Flavianum (Ep. 28)

Leo gave the Council of Chalcedon a letter it could build on. His Tome to Flavian explained Christ as one person in two natures, without confusion and without division, and the council received it as a decisive statement of orthodox Christology. Leo also strengthened the role of the Bishop of Rome as a teacher and negotiator in a West under pressure. The meeting with Attila in 452 became the famous image, but the Tome is the deeper reason his influence lasted.
