Jeremiah 31:32

Learn, all of you—learn! What better law of God is there, after all, than the holy gospel? It is the law of the New Testament, about which you heard, when the prophet was read, "Behold, the days are coming, says the Lord, I will perfect on the house of Jacob a new testament, not like the testament that I laid down for their ancestors when I led them from the land of Egypt." The testament (or covenant) is promised there, delivered here. It is promised through the prophet, delivered through the Lord of the prophets.

"But I," he says, "hold on to what God handed over to Moses." Listen to what God says through the prophet. What is God telling Jeremiah? "Behold, the days are coming, says the Lord, I will confirm on the house of Jacob a new covenant." Leave the old aside, take up the new, and you can see that you ought to leave aside circumcision, and unleavened bread taken literally, and the sabbath taken literally and the sacrifices taken literally. Listen to how the new covenant is promised: "Behold, the days are coming, says the Lord, I will confirm for them a new covenant, not like the covenant that I gave to their ancestors when I brought them out of the land of Egypt," when the law of commandments was given, when the people were led through the desert. It is not like that that I will give the new covenant. So do not go on wearing the old tunic. That was what crucified Christ. Your parent crucified him; you hate him. He by his own hand, you in your heart, both of you have carried out the crime. Therefore be displeased with what your parent did, and listen to what your Lord has done.

(Verse 31, 32.) Behold, days are coming, says the Lord, when I will strike (or establish) the house of Israel and the house of Judah with a new covenant (or testament), not like the covenant (or testament) that I made with their fathers on the day when I took them by the hand to bring them out of the land of Egypt. The covenant (or testament) that they broke, though I was their master (or I disregarded them), says the Lord. And ((Vulg. but)) this will be the covenant (or testament) that I will make with the house of Israel after those days, says the Lord: I will put my law within them, and I will write it on their hearts, and I will be their God, and they shall be my people. And no longer shall each one teach ((Vulg. man and man)) his neighbor, and each his brother, saying, 'Know the Lord,' for they shall all know me, from the least of them to the greatest, declares the Lord. For I will forgive their iniquity, and I will remember their sin no more. The apostle Paul, or someone else, wrote the Epistle to the Hebrews, and all subsequent Ecclesiastical men say that everything was fulfilled in the first coming of the Savior, and that the new Testament, that is, the Gospel, succeeded the old Testament, from which the law of the letter was changed to the law of the spirit, so that all sacrifices, circumcision, and the Sabbath were spiritually fulfilled. But as for the covenant we set forth as Testament, it is of Hebrew truth, although it is correctly called a Testament, because the will and testimony of those who enter into the covenant are contained in it. When Israel was brought out of the land of Egypt, there was such a familiarity with God in that people that it is said that their hand was held and a covenant was made, which they made void, and therefore the Lord neglected them. […]

For the grace of the law, which has passed away, we have received the abiding grace of the gospel, and, instead of the shadows and figures of the ancient covenant, truth has come by Jesus Christ. Jeremiah also prophesies in the person of God: "Behold, the days shall come, says the Lord, when I will make a new covenant with the house of Israel and with the house of Judah; not according to the covenant that I made with their ancestors, in the day that I took them by the hand to bring them out of the land of Egypt." Notice what he says, that it is not to the people of the Gentiles, with whom he had not previously made a covenant, but to the people of the Jews, to whom he had given the law by Moses, that he promises the new covenant of the gospel, so that they might no longer live according to the ancient letter but in the newness of the Spirit.

There was a law, and there is a law. ("For the law of the Spirit of life hath made me free.") There was a service, and there is a service. ("To whom pertaineth the service"; and again: "Serving God in the Spirit.") There was a covenant, and there is a covenant. ("I will make with you a new covenant, not according to the covenant which I made with your fathers.") There was a sanctification, and there is a sanctification: there was a baptism, and there is a Baptism: there was a sacrifice, and there is a Sacrifice: there was a temple, and there is a temple: there was a circumcision, and there is a circumcision; and so too there was a "grace," and there is a "grace." But the words in the first case are used as types, in the second as realities, preserving a sameness of sound, though not of sense. So in patterns and figures, the shape of a man scratched with white lines upon a black ground is called a man as well as that which has received the correct coloring; and in the case of statues, the figure whether formed of gold or of plaster, is alike called a statue, though in the one case as a model in the other as a reality.
