Gregory of Nazianzus
Also known as: Gregory the Theologian
Gregory of Nazianzus (c. 329–390) was a Cappadocian bishop, preacher, and poet known as the Theologian, whose Five Theological Orations shaped Trinitarian doctrine.
## Who Was Gregory of Nazianzus?
Gregory of Nazianzus was a bishop, preacher, and poet from Cappadocia in central Turkey. He was born around 329 near the town of Nazianzus, where his father was bishop. He studied for about ten years in Athens, where he became close friends with Basil.
Gregory wanted a quiet life of study and prayer. The church kept calling him out of it. The Eastern church gives him the title the Theologian, a title it shares only with the apostle John and Symeon the New Theologian.
## Major Works
Theological Orations, five sermons (Orations 27 through 31) preached in 380.
About 45 orations in all, including his defense of fleeing the priesthood (Oration 2) and his funeral sermon for Basil (Oration 43).
Letters, about 245 surviving, including Letters 101 and 102 to Cledonius on the person of Christ.
Poems, several hundred, including a long autobiographical poem.
## Theological Orations
In 379 Gregory went to Constantinople to lead a small congregation that held to the Nicene faith. Most churches in the city were in Arian hands. He met in a house chapel he named Anastasia, meaning resurrection.
There he preached the Five Theological Orations. They defend the full deity of the Son and the Spirit with clarity and force. In Oration 31 he asks directly whether the Spirit is God and answers yes, and so of one substance with the Father.
## Letters
Gregory’s letters to Cledonius answered Apollinarius, who taught that Christ had no human mind. Gregory replied with a principle theologians still quote: what He has not assumed, He has not healed. If Christ did not take a full human nature, then human nature is not fully saved.
## Defense of the Trinity and Refinement of Doctrine
In 381 Gregory presided for a time over the Council of Constantinople. That council completed the Nicene Creed with the article on the Holy Spirit. Opposition within the council pushed him to resign as bishop of Constantinople. He returned to Cappadocia, wrote poetry, and died around 390.
In Oration 31 he explains why the Spirit’s deity was taught gradually. The Old Testament proclaimed the Father openly and the Son less clearly. The New Testament revealed the Son and hinted at the Spirit’s deity. Now the Spirit dwells among us and gives a clearer demonstration of Himself.
## Pastoral Care
In 361 his father ordained him a priest against his will, and Gregory fled. Oration 2 explains why. He calls the guiding of souls the art of arts and the science of sciences. A physician treats bodies. A pastor must treat the soul, and every soul needs different care.
Pope Gregory the Great drew on this oration two centuries later in his Pastoral Rule.
