What Is Covenant Theology?
Last updated: 2026-09-08
Covenant theology is the framework through which Scripture organizes God's redemptive dealings with humanity, primarily centered on the Covenant of Works made with Adam and the Covenant of Grace established in Christ. While Reformed traditions broadly agree on these categories, Presbyterian and Baptist traditions differ on the relationship between these covenants and the administration of the church.
The Covenants of Works and Grace
Covenant theology understands the Bible as a narrative of God's redemptive promises. The WCF Ch.7 §2 outlines the Covenant of Works, where Adam stood as the representative of all mankind under a requirement of perfect obedience. Consequently, the 1689 LBCF Ch.7 §3 emphasizes that salvation is found only through the Covenant of Grace, which is rooted in an eternal transaction between the Father and the Son to redeem the elect.

The Redeemer and the Testament
The Covenant of Grace serves to deliver the elect from the misery of sin through the work of a Redeemer. As noted in the WSC Q.20, this covenant is the vehicle by which God brings His people into an estate of salvation. This arrangement is often described as a testament, finalized by the death of Christ. The author of Hebrews writes: Hebrews 9:15.

Covenant theology views Scripture as a unified narrative of God’s redemptive purpose, primarily organized through the Covenant of Works with Adam and the Covenant of Grace established in Christ. Reformed traditions hold that these covenants reflect God's unchanging nature, though they debate the extent to which the Old Testament and New Testament administrations differ in their membership and outward signs.
The Covenant of Works and the Covenant of Grace
The foundation of covenant theology is the distinction between the Covenant of Works, where perfect obedience was required of Adam for life, and the Covenant of Grace, which God graciously established after the Fall. As noted in the 1689 LBCF Ch.7 §2, the Covenant of Grace is made freely by God with sinners, promising life and salvation by faith in Christ. This reflects the teaching that the covenant of grace was made with Christ as the second Adam, and in him with all the elect as his seed (Westminster Larger Catechism Q.31).

Differing Administrations
While Reformed traditions agree there is one way of salvation, they differ on how the covenant is administered. The Westminster Larger Catechism Q.33 highlights that while the covenant is the same, its administration changed from the Old Testament to the New. Particular Baptists, following 1689 LBCF Ch.7 §6, emphasize that the New Covenant is specifically marked by the law being written on the hearts of the regenerate and the fuller knowledge of Christ, distinguishing it more sharply from the national and typical structure of the Mosaic covenant.
