2 Again, that they might remove the rebuking and judicial power from the Father, reckoning that as unworthy of God, and thinking that they had found out a God both without anger and [merely] good, they have alleged that one [God] judges, but that another saves, unconsciously taking away the intelligence and justice of both deities. For if the judicial one is not also good, to bestow favours upon the deserving, and to direct reproofs against those requiring them, he will appear neither a just nor a wise judge. On the other hand, the good God, if he is merely good, and not one who tests those upon whom he shall send his goodness, will be out of the range of justice and goodness; and his goodness will seem imperfect, as not saving all; [for it should do so,] if it be not accompanied with judgment.
