Only with difficulty did Saint Gregory survive the loss of his brother and guide. He delivered a funeral oration for him, and completed Saint Basil’s study of the six days of Creation, the Hexaemeron. That same year Saint Gregory participated in the Council of Antioch against heretics who refused to recognize the perpetual virginity of the Mother of God. Others at the opposite extreme, who worshipped the Mother of God as being God Herself, were also denounced by the Council. He visited the churches of Arabia and Palestine, which were infected with the Arian heresy, to assert the Orthodox teaching about the Most Holy Theotokos. On his return journey Saint Gregory visited Jerusalem and the Holy Places.

In the year 381 Saint Gregory was one of the chief figures of the Second Ecumenical Council, convened at Constantinople against the heresy of Macedonius, who incorrectly taught about the Holy Spirit. At this Council, on the initiative of Saint Gregory, the Nicean Symbol of Faith (the Creed) was completed. Together with the other bishops Saint Gregory affirmed Saint Gregory the Theologian as Archpastor of Constantinople. In the year 383, Saint Gregory of Nyssa participated in a Council at Constantinople, where he preached a sermon on the divinity of the Son and the Holy Spirit. In 386, he was again at Constantinople, and he was asked to speak the funeral oration in memory of the empress Placilla. Again in 394 Saint Gregory was present in Constantinople at a local Council, convened to resolve church matters in Arabia.

Saint Gregory of Nyssa was a fiery defender of Orthodox dogmas and a zealous teacher of his flock, a kind and compassionate father to his spiritual children, and their intercessor before the courts. He was distinguished by his magnanimity, patience and love of peace. Having reached old age, Saint Gregory of Nyssa died soon after the Council of Constantinople. Together with his great contemporaries, Saints Basil the Great and Gregory the Theologian, Saint Gregory of Nyssa had a significant influence on the Church life of his time. His sister, Saint Macrina, wrote to him: “You are renowned both in the cities, and gatherings of people, and throughout entire districts. Churches ask you for help.” Saint Gregory is known in history as one of the most profound Christian thinkers of the fourth century. Endowed with philosophical talent, he saw philosophy as a means for a deeper penetration into the authentic meaning of divine revelation. Saint Gregory left behind many remarkable works of dogmatic character, as well as sermons and discourses. He has been called “the Father of Fathers.”

Scripture: (Wisdom 7:24–8:1)

Wisdom is more mobile than any motion;
because of her pureness she pervades and penetrates all things.
For she is a breath of the power of God,
and a pure emanation of the glory of the Almighty;
therefore nothing defiled gains entrance into her.

For she is a reflection of eternal light,
a spotless mirror of the working of God,
and an image of his goodness.

Although she is but one, she can do all things,
and while remaining in herself, she renews all things;
in every generation she passes into holy souls
and makes them friends of God, and prophets;
for God loves nothing so much as the person who lives with wisdom.

She is more beautiful than the sun,
and excels every constellation of the stars.
Compared with the light she is found to be superior,
for it is succeeded by the night,
but against wisdom evil does not prevail.

She reaches mightily from one end of the earth to the other, and she orders all things well.
