During the reign of Emperor Alexius Comnenus, who reigned from 1081 to 1118, a controversy arose in Constantinople, dividing men enlightened in matters of faith and zealous in the acquisition of virtues into three camps. The debate centered on three saints and outstanding Fathers of the Church: Basil the Great , Gregory the Theologian , and John Chrysostom . Some favored St. Basil over the other two, as he was able to explain the mysteries of nature like no other and was elevated by virtue to angelic heights. His supporters argued that there was nothing base or earthly about him; he was the organizer of monasticism, the leader of the entire Church in the struggle against heresies, and a strict and demanding pastor regarding moral purity. Therefore, they concluded, St. Basil stood above St. John Chrysostom, who was more inclined to forgive sinners.
The other party, on the contrary, defended Chrysostom, countering that the renowned bishop of Constantinople, no less than St. Basil, was committed to combating vices, calling sinners to repentance, and urging the people to perfection according to the Gospel commandments. Unrivaled in eloquence, the golden-mouthed pastor flooded the Church with a veritable river of sermons. In them, he expounded on the Word of God and demonstrated its application in everyday life, and he succeeded in doing so better than the other two Christian teachers.
The third group advocated recognizing St. Gregory the Theologian as the most important, citing the grandeur, purity, and depth of his language. They argued that St. Gregory, who best mastered the wisdom and eloquence of the Greek world, attained the highest level of contemplation of God, and therefore no other person could have so magnificently expounded the doctrine of the Holy Trinity.
