A Letter to the Churches: One Covenant, One People, One Promise

A historical and biblical defense of covenant theology, the unity of God’s people, and the covenant inclusion and baptism of believers’ children.

A Letter to the Churches: One Covenant, One People, One Promise

Dear brothers and sisters,

Grace and peace to you from God our Father and the Lord Jesus Christ.

I write concerning the unity of God’s work of redemption, the place of our children within the visible people of God, and a system of interpretation that has taught generations of Christians to divide what God has joined together. That system is commonly called dispensationalism.

Many sincere believers received dispensational teaching through Sunday-school charts, study-Bible notes, and sermons about Israel and the Church. Because these teachings were printed alongside the biblical text, they came to seem as ancient as Scripture itself. But the Church did not historically read the Bible as two parallel peoples with separate covenant destinies. Christians understood themselves as heirs of Abraham’s promise and participants in the one purpose of God fulfilled in Christ.

The early Church did not possess the later terminology of the Westminster Confession. Yet the unity of Scripture, continuity of promise, and inclusion of believers’ children within the visible Church did not originate in the seventeenth century. It is dispensationalism that represents the historical interruption—and nowhere are its consequences more personal than at the baptismal font.

One Gospel from the Beginning

The Bible does not tell of God repeatedly abandoning one plan and beginning another. It tells of one gracious purpose unfolding from promise to fulfillment. After Adam fell, God promised that the seed of the woman would crush the serpent. He preserved Noah, called Abraham, redeemed Israel, established David’s throne, and spoke through the prophets of the coming Servant and King. At every stage, Christ was the substance toward which the shadows pointed.

Paul calls Abraham “the father of all who believe” (Romans 4:11), declares that “those of faith” are his sons (Galatians 3:7), and says, “If you are Christ’s, then you are Abraham’s offspring, heirs according to promise” (Galatians 3:29).

This is not replacement. Gentiles have been grafted into the same cultivated olive tree. Unbelieving branches were broken off, believing Gentiles grafted in, and Jewish branches may be grafted in again through faith in their Messiah. The tree remains one. The promise remains gracious. The people of God are defined finally by union with Christ, the true Seed.

The Church in the Wilderness

Stephen spoke of Israel as “the church in the wilderness” (Acts 7:38). Paul says Israel drank from the spiritual Rock, “and the Rock was Christ” (1 Corinthians 10:4). Abraham believed God, and it was counted to him as righteousness.

There has only ever been one way of salvation: by grace alone, through faith alone, in Christ alone. The saints before Christ trusted the promise as then revealed; we trust the Christ who has come. This is why Abraham is our father, the Psalms our songs, the prophets heralds of our Savior, and the promises “Yes” and “Amen” in Christ.

Dispensationalism weakened this inheritance by teaching Christians to file much of Scripture under “Israel” and keep it at a distance. The result has often been a Church alienated from her own Bible.

What Covenant Theology Teaches

Covenant theology recognizes real development across history. Noah did not receive the Mosaic ceremonial law; Abraham did not administer the Lord’s Supper; Pentecost brought new-covenant fullness. The question is whether these developments belong to one saving purpose centered upon Christ or to separate divine peoples and programs.

Reformed churches speak of the covenant of works and the covenant of grace. In Adam, man owed perfect obedience and came under death. After the fall, God revealed the covenant of grace, freely giving salvation through the promised Mediator. Its administrations differed, but its saving substance remained Christ.

The new covenant is new because Christ has come, sacrifice is accomplished, shadows yield to substance, and the Spirit is poured out. It is not new because God discarded His former people and adopted an unrelated principle.

The Ancient Church and the Unity of Scripture

The early Church read Scripture covenantally before later Reformed terminology was systematized. The fathers saw the Church as the gathering of the nations into Israel’s Messiah, not an unforeseen interruption.

Irenaeus described the unity of God’s saving work through successive covenants. Augustine understood the old and new administrations as differing outwardly while pointing to the same saving reality. The fathers were not infallible or uniform in every detail, but the broad pattern is unmistakable: the sharp Israel–Church division of classical dispensationalism was foreign to them.

A Nineteenth-Century Disruption

Dispensationalism in recognizable modern form arose in the nineteenth century through John Nelson Darby and the Plymouth Brethren. Darby divided Israel and the Church with a sharpness previously unknown in mainstream Christianity: Israel as God’s earthly people, the Church as His heavenly people, and the Church age as a parenthesis within God’s dealings with national Israel.

These ideas spread through prophecy conferences, Bible institutes, pamphlets, and C. I. Scofield’s reference Bible of 1909 and 1917. Scofield’s notes appeared beside the King James text. For readers without historical theology, the distinction between inspired text and interpretive system blurred. A novel framework acquired the appearance of antiquity because it was printed beneath ancient words.

This does not place every dispensationalist outside the faith. Many sincerely confess the Trinity, Christ’s deity, biblical authority, substitutionary atonement, and justification by faith. Charity requires honesty about them, but not silence about a system that fragments Scripture and obscures the Church’s relation to Abraham.

The Promise Is to You and to Your Children

“I will establish my covenant between me and you and your offspring after you throughout their generations for an everlasting covenant.” — Genesis 17:7

God addressed Abraham not as an isolated individual but as head of a household. The child received the sign not after producing a credible profession, but because God dealt covenantally with believers and their children.

This did not mean every circumcised child was regenerate. The sign marked visible covenant membership and declared God’s promise and the recipient’s obligation to faith.

At Pentecost Peter did not announce the household principle’s abolition: “Repent and be baptized … For the promise is for you and for your children and for all who are far off” (Acts 2:38–39). Gentiles are not placed into a covenant poorer than Abraham’s. The new covenant expands to the nations; it does not contract to isolated individuals.

Removing believers’ children would have been an enormous change for Jewish Christians. The New Testament nowhere announces it.

Households and Holy Children

Acts records the baptisms of Lydia’s household, the Philippian jailer’s family, and Stephanas’s household. The argument does not depend on proving an infant in each home. The importance is the persistence of the household pattern as the gospel enters the nations.

Paul says the children of even one believing parent are not unclean but holy (1 Corinthians 7:14). These are covenantal categories. If the child is holy—set apart from the world within the visible people of God—why withhold the sign of belonging?

Circumcision and Baptism

Paul connects circumcision and baptism in Colossians 2:11–12. They are not identical in every respect, but both mark entrance into the visible covenant community and point beyond themselves to God’s inward work.

Baptism does not automatically regenerate a child. A baptized child must repent and believe. Yet circumcision never eliminated faith’s necessity. It placed the child under covenant promises, obligations, worship, discipline, and instruction.

Paedobaptism does not presume regeneration. It presumes God’s faithfulness to deal with believers and their children according to His promise.

The Early Church and Infant Baptism

Tertullian, around the beginning of the third century, recommended delaying baptism for certain little children. His objection proves the practice already existed. Men do not argue for delaying what no one is doing.

Origen stated that the Church received from the apostles the tradition of baptizing infants. In the third century, Cyprian and a council of North African bishops considered whether baptism should wait until the eighth day after birth. Their conclusion was not to wait for a profession, but that baptism should not be withheld even until the eighth day. By Augustine’s time, infant baptism was treated as the received practice of the universal Church.

The fathers did not explain baptism identically to later Reformed theology. But infant baptism appears early and broadly without any record of entering as a controversial innovation.

The Baptist Covenant Argument

Not every credobaptist is dispensational. Particular Baptists, especially modern confessional Baptists who appeal to the 1689 London Baptist Confession, affirm the doctrines of grace and employ a form of covenantal interpretation. They nevertheless argue from Jeremiah 31—“they shall all know me”—that the new-covenant sign belongs only to professed believers.

This deserves a serious answer, yet it confuses the covenant’s inward substance with its visible administration. Every true member savingly united to Christ knows the Lord. Nevertheless, the visible New Testament Church still includes false professors, branches later cut off, and people warned against falling away.

No minister can see election or regeneration. Baptists therefore do not baptize the certainly regenerate; they baptize those capable of a credible profession. Scripture never establishes that ability as the exclusive basis for administering the covenant sign.

The Logical Conclusion of Each System

Classical dispensationalism separates Israel and the Church. Circumcision belongs to Israel and baptism to a distinct Church people. Credobaptism follows logically.

Particular Baptist federalism argues that visible new-covenant membership should correspond as closely as possible to regenerate membership. Credobaptism follows because personal profession becomes the evidence of entrance.

Reformed covenant theology sees one covenant of grace through successive administrations. The Church is the mature, international covenant people gathered around Israel’s Messiah. Believers remain Abraham’s children, and God nowhere revoked the inclusion of their children. Paedobaptism follows.

If children were once included and the new covenant never excludes them, the burden of proof rests upon the one who removes them. If Gentiles are grafted into Abraham’s tree, they do not enter with fewer privileges. If the promise is to believers and their children, the sign belongs to both.

Do Not Forbid the Children

“Let the children come to me; do not hinder them, for to such belongs the kingdom of God.” — Mark 10:14

This is not by itself a baptismal formula, but it reveals the character of Christ’s kingdom. He does not treat believers’ children as strangers outside until they demonstrate adult understanding.

The Church should receive covenant children, mark them with the triune name, catechize them, bring them under the Word, and call them to embrace Christ. Baptism does not make repentance unnecessary. It places God’s promise and obligation upon them and warns that covenant privilege intensifies judgment when met with unbelief.

Recover the Whole Bible

Covenant theology is not a clever grid imposed upon disconnected texts. It is Scripture’s unfolding account of promise and fulfillment. God did not fail with Israel and improvise the Church. Christ did not establish a parenthesis. The apostles did not detach believers from Abraham. The new covenant does not make grace less generous to believers’ households.

Let us resist a late-arriving system that divided God’s people and taught Christians to treat much of their inheritance as someone else’s. Let us read Moses, the prophets, the Psalms, the Gospels, and the apostles as one Word revealing one Savior.

And let us give our children the sign God has not forbidden—not because water saves, ancestry regenerates, or parental faith substitutes for their own, but because God deals covenantally with His people and their households.

The covenant has been fulfilled, not abolished. The people have been enlarged, not divided. The sign has been transformed, not withdrawn.

“I will be God to you and to your offspring after you.” — Genesis 17:7

Grace and peace be with you all.
