Gregory of Nazianzus — on 1Tim 6:15 (ORATIONS 30.19)

“God's other titles fall into two distinct groups. The first group belongs to his power, the second to his providential ordering of the world, a twofold providential ordering—involving, and not involving, incarnation. Clear cases of titles which belong to his power are … "King" of "rulers" and "Lord of the masters." … For since we are controlled by three conditions—fear of punishment, hope for salvation and glory too, and the practice of the virtues which result in these last—the name which mentions retribution deals with fear. The one which mentions salvation with hope, and that which refers to virtues, disciplines us to practice them. The intention is that by, as it were, carrying God inside him, one may have some success here and press on all the harder to perfection, toward that affinity with God which comes from the virtues.”
