Word has appeared, and fear is turned to love, and that mystic angel is born—Jesus. For this same Instructor said then, "Thou shalt fear the Lord God;"[1] but to us He has addressed the exhortation, "Thou shalt love the Lord thy God."[2] Wherefore also this is enjoined on us: "Cease from your own works, from your old sins;" "Learn to do well;" "Depart from evil, and do good;" "Thou hast loved righteousness, and hated iniquity." This is my new covenant written in the old letter. The newness of the word must not, then, be made ground of reproach. But the Lord hath also said in Jeremiah: "Say not that I am a youth: before I formed thee in the belly I knew thee, and before I brought thee out of the womb I sanctified thee."[3] Such allusions prophecy can make to us, destined in the eye of God to faith before the foundation of the world; but now babes, through the recent fulfilment of the will of God, according to which we are born now to calling and salvation. Wherefore also He adds, "I have set thee for a prophet to the nations,"[4] saying that he must prophesy, so that the appellation of "youth" should not become a reproach to those who are called babes.

Wherefore it was only temporary; but eternal grace and truth were by Jesus Christ. Mark the expressions of Scripture: of the law only is it said "was given;" but truth being the grace of the Father, is the eternal work of the Word; and it is not said to be given, but to be by Jesus, without whom nothing was.[6] Presently, therefore, Moses prophetically, giving place to the perfect Instructor the Word, predicts both the name and the office of Instructor, and committing to the people the commands of obedience, sets before them the Instructor. "A prophet," says he, "like me shall God raise up to you of your brethren," pointing out Jesus the Son of God, by an allusion to Jesus
