The reason he came
Do you ask the reason why God was born among men? If you take out of life the various benefits bestowed on us by God, you will not be able to say what means you have of recognizing the divine. For it is by the blessings we enjoy that we recognize our benefactor, seeing that we look at things that befall us, and from them we infer the nature of him who occasions them. If, then, love towards man is a special feature of the divine nature, you have the explanation for which you asked. You have the reasons for the presence of God among men.
For our nature, being weak, needed a healer. Man, who had fallen, needed someone to raise him up. He who had lost life needed a life-giver. He who had fallen away from the participation in good needed someone to restore him to good. He who was shut up in darkness needed the presence of the light. The captive sought someone to ransom him. He who was bound sought someone to help him. He who was held in the yoke of slavery sought someone to set him free. Were these slight and unworthy reasons to importune God to come down to visit human nature, seeing that humanity was in so pitiable and wretched a condition?
Gregory of Nyssa
Gregory of Nyssa (c.335-395) was born in Cappadocia (in present-day Turkey). He came from a large family that would prove to be very influential in the life of the Eastern church. Gregory’s own thought was primarily influenced by his older sister, Macrina, and his older brother, Basil. Gregory is known as one of the Cappadocian Fathers, along with his brother, Basil the Great, and Gregory of Nazianzus. He made significant contributions to the doctrine of the Trinity and the Nicene Creed.
