The saints behind the name

Basil the Great
January 1, Great Feast, Βασίλειος
St. Basil the Great was born in Caesarea of Cappadocia in the fourth century, to a family of saints. Educated in Athens alongside his friend St. Gregory the Theologian, he set aside a brilliant secular career for the monastic life, and later served as Archbishop of Caesarea. He defended the divinity of Christ against Arianism, gave the Church the Divine Liturgy that bears his name, and organized one of the first great centers of Christian charity for the poor and the sick.

Three Holy Hierarchs
January 30, Great Feast, Τρεις Ιεράρχαι
The feast of the Three Holy Hierarchs honors together Sts. Basil the Great, Gregory the Theologian, and John Chrysostom, the great fathers and ecumenical teachers of the Church. According to tradition, the common feast was established in the eleventh century after disputes arose in Constantinople over which of the three was greatest; the hierarchs made known in a vision that they are one before God, and a shared commemoration was appointed.

Basil the Confessor
February 28, Venerable, Βασίλειος
St. Basil the Confessor was a monk of the eighth century and the companion in asceticism of St. Prokopios of the Dekapolis. When the iconoclast heresy broke out, he stood with his fellow ascetic in defense of the veneration of the holy icons, and for this confession he endured imprisonment and ill-treatment.
