Irenaeus of Lyons · a new plain-English translation from the original language
A demonstration that the things according to the Law and the things according to the Gospel are of one and the same substance, and how the New Testament was foretold by the prophets. All things, then, are of one and the same source, that is, from one and the same God, as the Lord also said to his disciples: Therefore every scribe instructed in the kingdom of heaven is like a householder who draws forth from his storehouse both new and ancient things. He did not teach that one man produces the ancient and a different man the new, but a single, identical person. For the Lord is the householder who rules over the whole household of the Father, giving to the servants — those still undisciplined — a law suited to them, but to the free, those justified by faith, giving fitting precepts, and to the sons opening up his own inheritance. Now by scribes and teachers of the kingdom of heaven he meant his own disciples, of whom he also says elsewhere to the Jews: Behold, I am sending you sages and men learned in scripture and instructors, and a number of these you will put to death and chase from town to town. Thus, in speaking of things new and old brought out of the treasure, he speaks without contradiction of two testaments: the old one, which was the giving of the Law that came before; and the new one, which he shows to be the way of life according to the Gospel — of which David speaks: Sing to the Lord a new song. And Isaiah: Sing to the Lord a new hymn: its beginning is that his name is glorified from the ends of the earth; his mighty deeds are proclaimed in the islands. Jeremiah says: Behold, I will bring about, he says, a fresh covenant, unlike the one I struck with your ancestors at Mount Horeb. Both testaments, then, were produced by one and the same householder, God's Word, our Lord and Savior Jesus Christ, who conversed both with Abraham and with Moses, and who has restored liberty to us in newness, and multiplied that grace which is from himself.
