The Three Holy Hierarchs
The Three Holy Fathers, Great Hierarchs and Ecumenical Teachers, St. Basil the Great, St. Gregory the Theologian and St. John Chrysostom are seen as the greatest of the Church Fathers whose teachings shaped Orthodox Theology. To honor their unparalleled contribution to education, their steadfast faith in God and incomparable pastoral and charitable activities, a common feast of the three great Saints was established by the Church in the 11th Century. Subsequently, the feast of the Three Hierarchs is associated with education and officially recognized as the greatest feast for Greek schools.
