Quote in context
Leo the Great on Christian dignity
Pope Leo I · Sermon 21 (On the Nativity) 3
“Christian, recognize your dignity, and becoming a partner in the divine nature, refuse to return to the old baseness by degenerate conduct.”
Plain English
Leo is preaching at Christmas. Because the Son has taken human nature, Christians must live in a way that fits their restored dignity.
Why it matters
The line joins incarnation and ethics: what Christ became changes how Christians live.
Who said it
Pope Leo I
c. 400 – 461 · Born in Tuscany · Roman West
Leo did two things. First, in 451, he sent his Tome to the Council of Chalcedon — a short letter laying out how Christ is one person in two natures — and the council read it and declared 'Peter has spoken through Leo.' That definition is still the test of orthodoxy in every mainstream church East and West. Second, when Attila the Hun came to sack Rome in 452, Leo rode out to meet him and Attila turned around. Whatever actually happened in that conversation, the symbolism stuck. After Leo, the Bishop of Rome is no longer just one bishop among many — he's the figure who speaks for the West and stands in for an empire that's collapsing.
