VIII. He then who would live the true life is enjoined first to know Him “whom no one knows, except the Son reveal (Him).” Next is to be learned the greatness of the Saviour after Him, and the newness of grace; for, according to the apostle, “the law was given by Moses, grace and truth came by Jesus Christ;” and the gifts granted through a faithful servant are not equal to those bestowed by the true Son. If then the law of Moses had been sufficient to confer eternal life, it were to no purpose for the Saviour Himself to come and suffer for us, accomplishing the course of human life from His birth to His cross; and to no purpose for him who had done all the commandments of the law from his youth to fall on his knees and beg from another immortality. For he had not only fulfilled the law, but had begun to do so from his very earliest youth. For what is there great or pre-eminently illustrious in an old age which is unproductive of faults? But if one in juvenile frolicsomeness and the fire of youth shows a mature judgment older than his years, this is a champion admirable and distinguished, and hoary pre-eminently in mind.
