For there is no other second goodness existing in the Son, save that which is in the Father. And therefore also the Savior Himself rightly says in the Gospel, “There is none good save one only, God the Father,” that by such an expression it may be understood that the Son is not of a different goodness, but of that only which exists in the Father, of whom He is rightly termed the image, because He proceeds from no other source but from that primal goodness, lest there might appear to be in the Son a different goodness from that which is in the Father. Nor is there any dissimilarity or difference of goodness in the Son. And therefore it is not to be imagined that there is a kind of blasphemy, as it were, in the words, “There is none good save one only, God the Father,” as if thereby it may be supposed to be denied that either Christ or the Holy Spirit was good. But, as we have already said, the primal goodness is to be understood as residing in God the Father, from whom both the Son is born and the Holy Spirit proceeds, retaining within them, without any doubt, the nature of that goodness which is in the source whence they are derived.
