Gregory of Nyssa and Eunomius of Cyzicus represent a polarity in fourth-century thought on the Trinity, one upholding the consubstantiality of the Father and the Son in accordance with the Nicene Creed, while the other insists that they are separated by an ontological gulf. Both from time to time make use of arguments from the Greeks schools which imply the compatibility of pagan and Christian thought; both also betray the common anxiety of Christian to remain true to the word of revelation which is superior to all merely human wisdom. The same tension can be seen, outside the bounds of this controversy, in Gregory’s treatise on the early deaths of infants.
