Synaxis of the Three Hierarchs: Basil the Great, Gregory the Theologian and John Chrysostom: During the eleventh century, disputes raged in Constantinople about which of the three hierarchs was the greatest. Some preferred Saint Basil (January 1), others honored Saint Gregory the Theologian (January 25), while a third group exalted Saint John Chrysostom (November 13).
Dissension among Christians increased. Some called themselves Basilians, others referred to themselves as Gregorians, and others as Johnites. By the will of God, the three hierarchs appeared to Saint John the Bishop of Euchaita (June 14) in the year 1084, and said that they were equal before God. “There are no divisions among us, and no opposition to one another.”
They ordered that the disputes should stop, and that their common commemoration should be celebrated on a single day. Bishop John chose January 30 for their joint Feast, thus ending the controversy and restoring peace.
This common feast of these three teachers was instituted a little before the year 1100, during the reign of the Emperor Alexis I Comnenus, because of a dispute and strife that arose among the notable and virtuous men of that time. Some of them preferred Basil, while others preferred Gregory, and yet others preferred John Chrysostom, quarreling among themselves over which of the three was the greatest.

Furthermore, each party, in order to distinguish itself from the others, assumed the name of its preferred Saint; hence, they called themselves Basilians, Gregorians, or Johannites. Desiring to bring an end to the contention, the three Saints appeared together to the saintly John Mavropous, a monk who had been ordained Bishop of Euchaita, a city of Asia Minor, they revealed to him that the glory they have at the throne of God is equal, and told him to compose a common service for the three of them, which he did with great skill and beauty.
Saint John of Euchaita (celebrated Oct. 5) is also the composer of the Canon to the Guardian Angel, the Protector of a Man’s Life. In his old age, he retired from his episcopal see and again took up the monastic life in a monastery in Constantinople. He reposed during the reign of the aforementioned Emperor Alexis Comnenus (1081-1118).
Each of these saints has his own feast day: St. Basil the Great, January 1; St. Gregory the Theologian, January 25; and St. John Chrysostom, January 27. This combined feast day, January 30, was instituted in the eleventh century during the reign of Emperor Alexius Comnenus. Once, a debate arose among the people concerning who among the three was the greatest. Some extolled Basil because of his purity and courage; others extolled Gregory for his unequaled depth and lofty mind in theology; still others extolled Chrysostom because of his eloquence and clarity in expounding the Faith.
Thus some were called Basilians, others Gregorians, and the third were called Johannites. This debate was settled by divine providence, to the benefit of the Church and to the even greater glory of the three saints. Bishop John of Euchaita (June 14) had a vision in a dream: At first all three of these saints appeared to him separately in great glory and indescribable beauty, and after that, all three appeared together.
They said to him: “As you see, we are one in God and there is nothing contradictory in us; neither is there a first or a second among us.” The saints also advised Bishop John to write a common service for them and to order a common feast day of celebration. Following this wonderful vision, the debate was settled in this manner: January 30 would be designated as the common feast of these three hierarchs. The Greeks consider this feast not only an ecclesiastical feast, but also their greatest national school holiday.
