Basilios, the Great, was born at Caesarea 329 A.D.   He is one of the "fathers" of the church.  He studied philosophy at Athens, and afterwards became an advocate in his native city.   He was converted and formed a Monastic society 370 A.D.   He succeeded Eusebius as bishop of Caesarea, and in the Greek and other Oriental churches he is highly honored as one of their chief saints.  He died 379 A.D.  He is said to have introduced the three monastic vows:  Obedience, chastity and poverty.
