“There is none good but one, God the Father.” This word they2 declare is peculiar to the Father of Christ, who, however, is different from the God who is creator of all things, to which creator he gave no appellation of goodness. Let us see now if, in the Old Testament, the God of the prophets and the Creator and Legislator of the word is not called good. What are the expressions that occur in the psalms? “How good is God to Israel, to the upright in heart!” and, “Let Israel now say that he is good, that his mercy endures for ever,” the language in the Lamentations of Jeremiah, “The Lord is good to those who wait for him, to the soul that seeks him.” As therefore God is frequently called good in the Old Testament, so also the Father of our Lord Jesus Christ is styled just in the Gospels. Finally, in the Gospel according to John, our Lord, when praying to the Father, says, “O just Father, the world has not known you.” And lest perhaps they should say that it was owing to his having assumed human flesh that he called the Creator of the world Father and styled him just, they are excluded from such a refuge by the words that immediately follow, “The world has not known you.” But, according to them, the world is ignorant of the good God alone. For the world unquestionably recognizes its Creator, the Lord saying that the world loves what is its own. Clearly, then, he whom they consider to be the good God is called just in the Gospels. Anyone may at leisure gather together a greater number of proofs, consisting of those passages, where in the New Testament the Father of our Lord Jesus Christ is called just, and in the Old also, where the Creator of heaven and earth is called good; so that the heretics, being convicted by numerous testimonies, may perhaps some time be put to the blush.
