Saint Leo I (The Great)
Feast Day: November 10
He was an Italian aristocrat, and was the first pope to have been called “The Great”. He is perhaps best known for having met Attila the Hun in 452 and persuading him to turn back from his invasion of Italy. He is also a Doctor of the Church, most remembered theologically for issuing the Tome of Leo, a document that was foundational to the debates of the Ecumenical Council of Chalcedon.
The Council of Chalcedon, the fourth ecumenical council, dealt primarily with Christology, and explained the orthodox definition of Christ’s being as the hypostatic union of two natures – Divine and Human – united in one person, “with neither confusion nor division”. This ecumenical council was followed by a major schism associated with Monophysitism, Miaphysistism, and Dyophysitism.
In his “Nativitate Domini” in the Christmas Day sermon, “Christian, Remember your Dignity”. Leo appears to articulate a fundamental and inclusive human dignity and equality, “The Saint, the Sinner, and the Unbeliever are all equal as sinners, and none is excluded in the call to happiness”. He proclaimed the “Equality and Dignity” of every person regardless of their state in life. According to the Martyrology he died on November 10th, 461. His feast day remains celebrated on this day in the Catholic Church.
