Near Mantua, northern Italy, AD 452

Attila’s army has torn through northern Italy, and Rome is next.1

An unarmed bishop rides out to meet him by the river Mincio.1

His name was Leo, and he came back with a promise that the Huns would leave Italy.

01St. Leo I (the Great)

Facing the Huns

Leo went in 452, with two Roman officials, to meet Attila near Mantua and obtained his promise to withdraw from Italy and negotiate peace.1

In 455, when the Vandals captured Rome, Leo’s intercession won a promise that the city’s people would be spared.1

02St. Leo I (the Great)

Peter has spoken

Leo’s pontificate is counted, with that of Gregory I, the most significant in Christian antiquity.1

His letter on the two natures of Christ was received at the Council of Chalcedon in 451.1

The Church professes that Christ is one person in two natures, true God and true man, as Chalcedon taught.2

Leo defended a city with his courage and the faith with his pen. The second mattered longer.

A century and a half later, a monk would become pope in a plague year.
