The Three 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 supreme contribution to education, their unshakable and zealous faith in God and their incomparable pastoral and charitable activities, the common feast of the three great Saints was established by the Church in the 11th Century. Since then, it has been common for the feast of the Three Hierarchs to be associated with education and officially recognized as the greatest feast for Greek schools.
