Leo the Great (Pope Leo I)
Bishop of Rome whose Tome of Leo established the Chalcedonian two-nature formula
Leo I was Pope of Rome whose dogmatic letter *Tome of Leo* (Epistle 28 to Flavian) defined orthodox Christology for the Council of Chalcedon (451 AD): 'Each form does what is proper to it with the cooperation of the other', acclaimed by the council fathers with the shout: 'Peter has spoken through Leo!'.
Historical Context & Significance
During the collapse of the Western Roman Empire, Leo personally persuaded Attila the Hun to turn back from Rome in 452 AD and negotiated with the Vandals in 455, establishing papal moral authority and the Petrine primacy in the West.
