St. Leo the Great
February 18, 2015
An event every year that begins at 12:00 am on day 18 of February, repeating indefinitely
Our holy father, Leo the Great, Pope of Rome, opposed the Nestorians and taught, like St. Cyril of Alexandria, the unity of person in Christ. He saved Rome from the invasion of Attila and died A.D. 461 during the reign of Emperor Leo the Great.
