128. Arius says: “[The Son is] of another Substance.” But what other substance is exalted to equality with the Son of God, so that simply in virtue thereof He is Son of God? Or what right have the Arians for censuring us because we speak, in Greek, of the οὐσία, or in Latin, of the Substantia of God, when they themselves, in saying that the Son of God is of another “Substance,” assert a divine Substantia.
