St. Basil the Great

(d. 379) was bishop of Caesarea in what is now Turkey and is known as one of the three great Cappadocian fathers, who championed orthodox trinitarian theology. A son to a wealthy and pious family of nobles, Basil devoted much of his energy and resources later in his life to the founding of a monastic community centered on prayer, education, and assisting the poor and diseased free of charge.
