From: Jeremiah 31:31-34
The New Covenant
*********************************************************************************************
Commentary:
31:31-37. The words of this oracle are central to Jeremiah’s message, and they
constitute the passage in the book that has had most impact on the New Testa-
ment and on Christian teaching. Most ancient and modern commentators consi-
der these words to be original words of Jeremiah, and they generally attribute
them to the early stages of his ministry, because they express support for King
Josiah’s religious reform.
The oracle is made up of two contrasting parts: the first (vv. 31-32) describes the
Old Covenant, broken by the people’s sins; the second (vv. 33-35) speaks very
forcefully of the New Covenant which will endure forever.
The old Covenant is described in terms of three characteristic features: it carried
the force of tradition because it was a pact made “with the fathers”; it was a sign
of divine election, as can be seen from a phrase exclusive to Jeremiah: “when “I
took them by the hand” to bring them out of the land of Egypt”; and it showed the
Lord’s authority over his people.
The new pact has three key features, too: it is “new”, it is something “interior”,
and it is “heartfelt”, written upon their hearts. It is “new”, because prior to this
the pact with God was never described in that way; that is, it is new not in terms
of the previous covenant which has ceased to operate (cf. Heb 8:18-13) but in the
sense that it is definitive and will not be superseded. When, at the Last Supper,
Jesus said the words of consecration over the chalice: “This cup which is poured
out for you is the new covenant” (Lk 22:20; 1 Cor 11:25), he brings Jeremiah’s
words to fulfillment. It is “interior” because it is etched in the heart of the people
and of each individual. Its content did not change (it is the Law of God) but peo-
ple will know it in a different way: the previous covenant was written on tablets
of stone (Ex 31:38; 34:28ff), but this one will be written on the heart and soul of
man. Therefore, it is part of a person’s very being; it is not just an external obli-
gation; people’s well-formed consciences tell them what they ought to do; if they
fail to live up to the demands of the Covenant, they lose their identity until they
are converted and are redeemed from sin. In the Letter to the Hebrews it says,
by way of explaining this passage, that in the New Covenant Christ has obtained
forgiveness of sins for us through the cross, and therefore the old sin offerings no
longer have any effect: “Where there is forgiveness (of sins), there is no longer
any offering for sin” (Heb 10:18).
Finally, it is “heartfelt” because it is based on a loving relationship between God
and his people. The wording that Jeremiah likes so much (”I will be their God,
and they shall be my people” (Jer 31:33; cf. 7:23) implies bonds, of fidelity and
love. The nearest precedent for this is Hosea, who used the metaphor of mar-
riage as the hinge of his preaching and who defined sin as estrangement from
God, and punishment in terms of marital breakdown: “Call his name not my peo-
ple, for you are not my people and I am not your God” (Hos 1:9). Therefore, mo-
ral imperatives should not come via legal imposition from outside; they should
arise from a person’s heart—the aim being not so much perfect, guiltless behavior
as living in union with God: “All who keep his commandments abide in him, and
he in them” (1 Jn 3:24).
The New Covenant has given its name to the, “New Testament”, on which the
new people of God is founded, as the Second Vatican Council says: “At all times
and in every race God has given welcome to whosoever fears him and does what
is right. God, however, does not make men holy and save them merely as indivi-
duals, without bond or link between one another. Rather has it pleased him to
bring men together as one people, a people that acknowledges him in truth and
serves him in holiness. He therefore chose the race of Israel as a people unto
himself. With it he set up a covenant. Step by step he taught and prepared this
people, making known in its history both himself and the decree of his will and
making it holy unto himself. All these things, however, were done by way of pre-
paration and as a figure of that new and perfect covenant, which was to be rati-
fied in Christ, and of that fuller revelation which was to be given through the Word
of God Himself made flesh. ‘Behold the days shall come saith the Lord, and I will
make a new covenant with the House of Israel, and with the house of Judah. [...]
I will give my law in their bowels, and I will write it in their heart, and I will be their
God, and they shall be my people.[...] For all of them shall know Me, from the
least of them even to the greatest, saith the Lord’ (Jer 31:31-34). Christ instituted
this new covenant, the new testament, that is to say, in his Blood, calling toge-
ther a people made up of Jew and Gentile, making them one, not according to
the flesh but in the Spirit” (”Lumen Gentium”, 9).
