In the Orthodox Church, we commemorate the Three Holy Hierarchs with a special feast every year. Who exactly are the Three Holy Hierarchs? They are St. Basil the Great, St. Gregory the Theologian, and St. John Chrysostom. All three were very well educated, all three were great leaders of the Church in the fourth or fifth centuries, and all three have left behind a legacy of love for Christ/service to others that continues to challenge every generation of Christians.
Hundreds of years after these hierarchs departed this life, the 11th century Christians began to disagree as to which of these three men was the greatest. This disagreement led to division. Some Christians began calling themselves Basilians; others, Gregorians; and still others, Johannites. The Three Hierarchs did not like to see their fellow Christians divided in this way, so by the grace of God, they appeared together to Bishop John Mauropos, a monk serving in Euchaita (in Asia Minor). They told him that none of them was greater before God than the other. They also asked that they all be celebrated together on the same day, as a reminder of this. Bishop John, following the saints’ instructions, wrote a service to commemorate the Three Holy Hierarchs, and he selected January 30 (Feb. 12) as the day to celebrate all three of them.

The three most great luminaries of the Three-Sun Divinity have illumined all of the world with the rays of doctrines divine and true; they are the sweetly-flowing rivers of wisdom, who with godly knowledge have watered all creation in clear and mighty streams: The great and sacred Basil, and the Theologian, wise Gregory, together with the renowned John, the famed Chrysostom of golden speech. Let us all who love their divinely-wise words come together, honoring them with hymns; for ceaselessly they offer entreaty for us to the Trinity.

“In Greece, the Three Hierarchs are the patron saints of learning. The Greek churches celebrate the Greek alphabet on the same day that they celebrate the Three Hierarchs. Not only were these saints protectors of the purity of the Orthodox Faith, but they also were promoters of the importance of education. On this day, it is customary to give school children books. Another idea is to give awards for excellence.” ~ http://myocn.net/three-holy-hierarchs-st-basil-great-st-gregory-theologian-st-john-chrysostom/
The Three Holy Hierarchs are excellent role models for both educators and students: “If we were to summarize the precepts of the three great hierarchs, we might say that they advise young people of any era: ‘Go on, ever forwards and ever upwards. Really want to be educated. Throw yourselves into your studies. Hunger to do something great and heroic. Learn to ignore yourselves and submit to the service of others. Do you dream of a better society? Work for it. Arm yourselves with vitality and persistence and live the love of Christ powerfully and ardently, until the end.’” ~ from http://pemptousia.com/2015/01/the-three-hierarchs-and-education/
