What is the New Covenant and how does it relate to Israel and the Church?
Question 10007
The New Covenant occupies a unique position among the biblical covenants because both Israel and the Church claim it as their own, and the question of how it relates to each has generated sustained theological debate. For covenant theology, the New Covenant is evidence that the Church has inherited the promises originally made to Israel. For dispensational theology, the New Covenant was made with Israel and will be fulfilled with Israel, while the Church participates in its spiritual blessings by virtue of union with the Messiah through whom the covenant is mediated. Getting this right matters enormously, because it shapes how the relationship between the two testaments is understood and what the future holds for both Israel and the Church.
The Old Testament Institution
The New Covenant is announced in Jeremiah 31:31–34 with unmistakable specificity: “Behold, the days are coming, declares the LORD, when I will make a new covenant with the house of Israel and the house of Judah, not like the covenant 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 recipients are named: the house of Israel and the house of Judah. The contrast is explicit: this is not like the Mosaic covenant, which Israel broke. The content is spelled out: God will put His law within them, write it on their hearts, be their God, and they will be His people. Every one of them will know the Lord, from the least to the greatest. And God will forgive their iniquity and remember their sin no more.
Ezekiel 36:25–27 adds further dimensions. God will sprinkle clean water on Israel, give them a new heart and a new spirit, remove the heart of stone and give a heart of flesh, and put His Spirit within them to cause them to walk in His statutes. The transformative, internal, and Spirit-empowered character of the New Covenant distinguishes it fundamentally from the external, conditional character of the Mosaic arrangement. The Mosaic covenant said, “Do this and live.” The New Covenant says, “I will do this in you.”
The New Covenant and Christ
Jesus Himself connects His sacrificial death to the New Covenant at the Last Supper. “This cup that is poured out for you is the new covenant in my blood” (Luke 22:20). The writer of Hebrews develops this at length, arguing that Jesus is the mediator of a “better covenant, enacted on better promises” (Hebrews 8:6) and that the New Covenant has rendered the old one “obsolete” (Hebrews 8:13). The blood of Christ is the basis on which the New Covenant operates. Without His death, there is no forgiveness, no new heart, no indwelling Spirit. Christ’s atoning work is the foundation on which everything the New Covenant promises is built.
This much is not in dispute. The theological question is: to whom does the New Covenant apply?
The Dispensational Understanding
The classical dispensational position holds that the New Covenant was made with Israel and will be fulfilled with Israel in the millennial kingdom. The language of Jeremiah 31 is addressed to the house of Israel and the house of Judah, not to a future entity that would be composed primarily of Gentile believers. The full realisation of the New Covenant, including the national knowledge of God, the universal indwelling of the Spirit within Israel, and the complete forgiveness that results in God remembering their sin no more, awaits Israel’s national conversion at the Second Coming (Zechariah 12:10; Romans 11:26).
The Church, however, genuinely participates in the spiritual blessings of the New Covenant. The indwelling of the Holy Spirit, the forgiveness of sins, and the internal transformation that marks regeneration are all New Covenant realities that believers in the present age experience. The question is whether this participation means the Church has replaced Israel as the covenant partner, or whether the Church shares in blessings that flow from a covenant whose ultimate fulfilment remains with its original recipients.
The dispensational answer is the latter. The Church partakes of New Covenant blessings because the covenant is mediated through Christ, and every believer is united to Christ. But the national, corporate, and territorial dimensions of the covenant, the dimensions Jeremiah and Ezekiel describe, await fulfilment with Israel. Paul hints at this arrangement in Romans 11:17–24, where Gentile believers are described as branches grafted into the olive tree, sharing in the “rich root” of Israel’s covenantal heritage without becoming Israel or replacing the natural branches.
The Covenant Theology Alternative
Covenant theology argues that the Church is the fulfilment of the New Covenant. The “house of Israel and the house of Judah” in Jeremiah 31 are understood typologically as pointing to the people of God in the new age, which is the Church. Since the Church includes both Jewish and Gentile believers, the promise has been fulfilled in a spiritual, expanded sense that transcends the original ethnic categories.
The difficulty with this reading is that it requires the interpreter to decide when “Israel” means Israel and when it means something else. In the same passage where Jeremiah names the house of Israel and the house of Judah as the covenant recipients, the surrounding context (Jeremiah 30–33) describes the physical restoration of the Jewish people to the land, the rebuilding of Jerusalem, and the establishment of a righteous Davidic king. If the New Covenant recipients have been spiritualised to mean the Church, then logical consistency requires the land, the city, and the king to be spiritualised as well. At what point does the text lose contact with what it was actually written to convey?
So, now what?
The New Covenant is not a theological abstraction. It is a blood-ratified commitment made by God to Israel, mediated through the death of Christ, and shared with the Church by grace. Every believer who experiences the indwelling Spirit, the forgiveness of sins, and the internal transformation of regeneration is tasting New Covenant reality. And every believer who trusts that God will keep His word to Israel, fulfilling Jeremiah 31 in its fullness at the return of Christ, has reason to trust that the same covenant-keeping God will fulfil every promise He has made to those who belong to His Son. The New Covenant is not either Israel’s or the Church’s. It is God’s, mediated through Christ, and it will be fulfilled to the letter because the God who made it does not lie.
