Saint Maximus the Confessor (also known as Maximus the Theologian and Maximus of Constantinople) (c. 580 - August 13, 662) was a Christian monk, theologian, and scholar. In his early life, he was a civil servant, and an aide to the Byzantine Emperor Heraclius. However, he gave up this life in the political sphere to enter into the monastic life.
After moving to Carthage, Maximus studied several Neo-Platonist writers and became a prominent author. When one of his friends began espousing the Christological position known as Monothelitism, Maximus was drawn into the controversy, in which he supported the Chalcedonian position that Jesus had both a human and a divine will. Maximus is venerated in both Eastern Christianity and Western Christianity. His positions eventually resulted in exile, soon after which he died. However, his theology was vindicated by the Third Council of Constantinople and he was venerated as a saint soon after his death. His feast day is August 13 (or January 21).
