Pope Saint Leo the Great served as Pope from 440 to 461 and is one of only three popes called “the Great.” He is best known for persuading Attila the Hun to turn back from invading Rome in 452, and for his Tome, a letter defining the two natures of Christ that was accepted at the Council of Chalcedon in 451.
