Mariology: Theotokos

Roman Catholic Mariology deals with the life and role of the Virgin Mary, the mother of Jesus, as well as her veneration, throughout the ages, in theology, prayer, hymns, art, music, and architecture.


Theotokos (Θεοτόκος) lit. "one who bears the One who is God"; a common title in Eastern Christianity with Christological implications; adopted officially during Council of Ephesus (431) in response to Nestorianism, which questioned the Church's teaching that Jesus Christ's nature was unified.
