Saint Basil of Caesarea, also called Basil the Great (between 329 and 333 - January 1, 379) (Greek: Άγιος Βασίλειος ο Μέγας; Latin: Basilius), was the Bishop of Caesarea in Cappadocia, and an influential 4th century Christian theologian. Theologically, Basil was a supporter of the Nicene faction of the church, in opposition to the Arians on one side and the Appollanarians on the other. His ability to balance his theological convictions with his political connections - especially with the Arian Emperor Valens - made Basil a powerful advocate for the Nicene position.
In addition to his work as a theologian, Basil was known for his care of the poor and underprivileged. He is considered a saint by the traditions of both Eastern and Western Christianity.
