Early Church
Pope Leo the Great
c. 400 – 461 · Rome
“And without controversy great is the mystery of godliness: God was manifest in the flesh.”
1 Timothy 3:16 (KJV)
In the Life of the Saints
Serving as pope during one of Christianity's most contentious theological disputes over the nature of Christ, Leo wrote a letter known as the Tome that helped settle the question at the Council of Chalcedon in 451, affirming that Christ was fully God and fully man in one person. He was also a skilled diplomat, credited with persuading Attila the Hun to turn back from an invasion of Rome in 452. He remains one of only four popes given the title “the Great.”
