Chapter 3: The Covenant of Redemption

The Covenant of Redemption reveals how Christ comes as the second Adam to accomplish what the first Adam failed to do. Meredith G. Kline therefore describes the two covenants in parallel terms: the Creator’s Covenant of Works with the first Adam and the Father’s Covenant of Works with Christ as the second Adam. In the order of God’s eternal purpose, the Covenant of Redemption precedes creation. In the order of revelation and pedagogy, however, the Covenant of Works with Adam helps us understand the character of Christ’s undertaking.

This lecture remains within the systematic-theological portion of the course. Later lectures will return to the biblical covenants—the Noahic, Abrahamic, Mosaic, Davidic, and new covenants—and show how they disclose the three theological covenants. The ultimate purpose is not merely to construct a system but to understand the person and work of Christ more fully.

Names for the Covenant

Pactum Salutis

The traditional Latin designation is pactum salutis, “the pact” or “agreement of salvation.” It emphasizes the eternal agreement within the Trinity concerning the salvation of the elect.

The Counsel of Peace

Some older theologians called it the “Counsel of Peace,” appealing to Zechariah 6:12–13:

“Behold, the man whose name is the Branch … It is he who shall build the temple of the LORD … and the counsel of peace shall be between them both.” —Zechariah 6:12–13

Johannes Cocceius understood “between them both” as referring to the LORD and the messianic Branch. Geerhardus Vos judged that application mistaken. In context, the text more probably describes the harmonious union of the priestly and kingly offices in the Messiah. The doctrine of the Covenant of Redemption does not depend on this verse, although the older title remained in use.

The Father’s Covenant of Works with Christ

Kline’s longer designation—“the Father’s Covenant of Works with Christ as the second Adam”—brings out the covenant’s legal structure. The Son undertakes to obey the law, bear its curse, and merit the promised inheritance for his people. This is not a covenant of grace for Christ. It is a covenant of works fulfilled by Christ so that its benefits may be given graciously to sinners.

The Unique Character of the Covenant of Redemption

The Covenant of Redemption is unique in two respects.

First, it is intra-trinitarian. All the other covenants considered in Scripture are made between God and creatures. This covenant concerns the Father, the Son, and the Holy Spirit within the life and purpose of the triune God.

Second, it is eternal. The historical covenants are enacted within time, but the Covenant of Redemption stands behind and above them. It is the eternal foundation of the mission of the Son, the outpouring of the Spirit, and the entire history of salvation.

These two features require careful theological language. The covenant must not be imagined as an agreement among three independent divine beings. There is one God, one divine essence, and one indivisible divine will. The covenant is the one eternal purpose of God personally expressed according to the distinct relations and missions of the Father, Son, and Spirit.

Historical Development

The fully developed terminology appeared in the seventeenth century, but the theological substance is older. Richard A. Muller describes a “dogmatic trajectory” running through early Reformed writers such as Johannes Oecolampadius, John Calvin, Caspar Olevianus, and Zacharias Ursinus.

The Canons of Dort contain an important precursor in their treatment of definite atonement:

“It was God’s will that Christ through the blood of the cross … should effectively redeem … all those and only those who were chosen from eternity to salvation and given to him by the Father.” —Canons of Dort, Second Head, Article 8

The language of an elect people given by the Father to Christ, and of Christ effectively redeeming those people, contains the essential structure of the later doctrine.

The Leiden Synopsis, composed soon after the Synod of Dort, further developed the idea of Christ’s appointment as mediator. The Westminster Confession likewise teaches that Christ purchased an everlasting inheritance for those whom the Father gave him:

“The Lord Jesus, by his perfect obedience, and sacrifice of himself … has fully satisfied the justice of his Father; and purchased … an everlasting inheritance in the kingdom of heaven, for all those whom the Father has given unto him.” —Westminster Confession 8.5

The first recorded use of the specific expression “Covenant of Redemption” appears in a 1638 speech by David Dickson before the General Assembly of the Church of Scotland. Refuting Arminianism, Dickson declared that “there is a Covenant of redemption betwixt God and the Mediator Christ, preceding the Covenant of Grace.” From the middle of the seventeenth century onward, the terminology became common in writers such as Cocceius, John Owen, and Herman Witsius.

The Terms of the Covenant of Redemption

Vos’s Definition

Vos defines the covenant as follows:

“It is the agreement between the will of the Father in giving the Son as head and redeemer of the elect and the will of the Son in presenting himself for them as surety.” —Geerhardus Vos, Reformed Dogmatics

A surety or guarantor undertakes responsibility for another person’s obligation. Hebrews applies this language to Christ:

“This makes Jesus the guarantor of a better covenant.” —Hebrews 7:22

Christ does not merely offer assistance to sinners so that they may satisfy the law themselves. He stands in their place, assumes their legal obligation, pays their debt, and fulfills the righteousness they owe.

David Dickson’s Summary

Dickson gives a fuller statement:

“God, having freely chosen unto life a certain number of lost mankind … did give them before the world began unto God the Son, appointed Redeemer, that upon condition he would humble himself so far as to assume the human nature … and submit himself to the law as a surety for them, and satisfy justice for them, by giving obedience in their name, even unto the suffering of the cursed death of the cross, he should ransom and redeem them all from sin and death, and purchase unto them righteousness and eternal life.” —David Dickson, The Sum of Saving Knowledge

This statement identifies both the condition undertaken by the Son and the reward pledged by the Father.

What the Father Required of the Son

The Father required the Son to assume a true human nature and become the federal head and surety of the elect. As the eternal Son, he stood above the law as its divine author. As the incarnate second Adam, he willingly placed himself under the law.

“When the fullness of time had come, God sent forth his Son, born of woman, born under the law, to redeem those who were under the law.” —Galatians 4:4–5

Christ fulfilled the condition through both active and passive obedience. His active obedience is his lifelong, perfect conformity to God’s law. He loved God with all his heart, soul, mind, and strength and loved his neighbor perfectly. Through that obedience he merited the right and title to eternal life for his people.

His passive obedience is his willing endurance of suffering and the covenant curse, culminating in the cross. “Passive” does not mean inactive. Christ actively offered himself, but he submitted to the penalties demanded by divine justice.

Vos summarizes the relation to Adam:

“Considered in this light, the work of Christ was a fulfillment of what Adam had not fulfilled, a carrying out of the demand of the covenant of works.” —Vos, Reformed Dogmatics

What the Father Pledged to Give the Son

The Father pledged to equip the incarnate Son with the Holy Spirit for his messianic work. At Jesus’ baptism the Spirit descended upon him, and the Father publicly identified him as the beloved Son. Isaiah’s servant prophecy stands behind this event:

“Behold my servant, whom I have chosen, my beloved with whom my soul is well pleased. I will put my Spirit upon him, and he will proclaim justice to the Gentiles.” —Matthew 12:18; cf. Isaiah 42:1

Jesus applies Isaiah 61 to himself:

“The Spirit of the Lord is upon me, because he has anointed me to proclaim good news to the poor.” —Luke 4:18

The Father also promised exaltation as the reward of Christ’s obedience:

“He humbled himself by becoming obedient to the point of death, even death on a cross. Therefore God has highly exalted him.” —Philippians 2:8–9

The “therefore” is covenantal. Christ’s exaltation is the judicial reward of his completed obedience. The Father raises him, enthrones him, gives him the nations, and places all things beneath his feet.

The exalted Christ receives the fullness of the Spirit in order to pour out the Spirit upon his church:

“Being therefore exalted at the right hand of God, and having received from the Father the promise of the Holy Spirit, he has poured out this that you yourselves are seeing and hearing.” —Acts 2:33

Finally, the Father guarantees the application of redemption to all those given to the Son. The Son does not merely make salvation possible. The Spirit effectually calls, justifies, sanctifies, preserves, and glorifies the elect for whom Christ acted.

“Ask of me, and I will make the nations your heritage, and the ends of the earth your possession.” —Psalm 2:8

The Spirit’s fundamental work is to minister to believers everything that belongs to them in Christ. The Son accomplishes redemption; the Spirit applies that accomplished redemption.

Biblical Proofs for the Covenant of Redemption

No single verse contains a complete systematic definition of the Covenant of Redemption. The doctrine arises from the convergence of many passages that describe the Son as sent by the Father, given a work to accomplish, acting for a definite people, receiving a promised reward, and applying redemption through the Spirit.

Psalm 40: The Son Comes to Do God’s Will

Hebrews places the words of Psalm 40 on the lips of Christ as he enters the world:

“Sacrifices and offerings you have not desired, but a body have you prepared for me; in burnt offerings and sin offerings you have taken no pleasure. Then I said, ‘Behold, I have come to do your will, O God, as it is written of me in the scroll of the book.’” —Hebrews 10:5–7; cf. Psalm 40:7–8

The Mosaic sacrifices were ordained by God and served their temporary purpose, but they could not accomplish final atonement. The Father prepared a body for the Son so that the Son might render the obedience and sacrifice to which the entire ceremonial system pointed. Christ enters history consciously committed to the will assigned to him.

Psalm 110 and the Priestly Oath

Psalm 110 combines Christ’s royal enthronement with his everlasting priesthood:

“The LORD says to my Lord: ‘Sit at my right hand, until I make your enemies your footstool.’ … The LORD has sworn and will not change his mind, ‘You are a priest forever after the order of Melchizedek.’” —Psalm 110:1, 4

The oath is especially significant because a covenant is an oath-bound commitment. Hebrews contrasts the Levitical priests, who entered office without such an oath, with Christ:

“Those who formerly became priests were made such without an oath, but this one was made a priest with an oath by the one who said to him: ‘The Lord has sworn and will not change his mind, You are a priest forever.’ This makes Jesus the guarantor of a better covenant.” —Hebrews 7:20–22

“The law appoints men in their weakness as high priests, but the word of the oath, which came later than the law, appoints a Son who has been made perfect forever.” —Hebrews 7:28

“The word of the oath” was historically revealed through David after the giving of the Mosaic law. The oath itself belongs to God’s eternal appointment of the Son as priest and surety. Psalm 110 discloses in history the eternal commitment that underlies Christ’s messianic mission.

Isaiah 53: Obedience, Sacrifice, Offspring, and Reward

Isaiah 53 contains the complete covenantal pattern of command, suffering, representative obedience, offspring, and reward:

“It was the will of the LORD to crush him; he has put him to grief; when his soul makes an offering for guilt, he shall see his offspring; he shall prolong his days; the will of the LORD shall prosper in his hand. Out of the anguish of his soul he shall see and be satisfied; by his knowledge shall the righteous one, my servant, make many to be accounted righteous, and he shall bear their iniquities. Therefore I will divide him a portion with the many, and he shall divide the spoil with the strong.” —Isaiah 53:10–12

The servant offers himself for guilt, bears the iniquities of the many, and makes them righteous. Because he pours out his soul to death, he receives the many as his portion. The language of “offspring,” satisfaction, and spoil describes the reward promised to the obedient servant.

The Gospel of John

B. B. Warfield called John “the Gospel of the Covenant” because Jesus repeatedly describes himself as sent by the Father to perform a specified work for a people given to him.

“My food is to do the will of him who sent me and to accomplish his work.” —John 4:34

“I seek not my own will but the will of him who sent me.” —John 5:30

“All that the Father gives me will come to me, and whoever comes to me I will never cast out. For I have come down from heaven, not to do my own will but the will of him who sent me. And this is the will of him who sent me, that I should lose nothing of all that he has given me, but raise it up on the last day.” —John 6:37–39

These passages contain the main elements of the doctrine: the Father gives a people to the Son; the Son comes from heaven on a mission; he obeys the Father’s will; he saves every person given to him; and he raises them at the last day.

Jesus’ obedience is voluntary and loving, not coerced:

“For this reason the Father loves me, because I lay down my life that I may take it up again. No one takes it from me, but I lay it down of my own accord … This commandment I have received from my Father.” —John 10:17–18

The Father’s command and the Son’s willing self-offering belong together. The Son does not obey as an unwilling servant but as the beloved Son whose will is perfectly united with the Father’s.

The high-priestly prayer in John 17 is especially important:

“Father, the hour has come; glorify your Son that the Son may glorify you, since you have given him authority over all flesh, to give eternal life to all whom you have given him … I glorified you on earth, having accomplished the work that you gave me to do. And now, Father, glorify me in your own presence with the glory that I had with you before the world existed.” —John 17:1–5

Christ presents his completed obedience and asks for the promised reward of glorification. He also claims authority to give eternal life to the definite people the Father has given him.

Romans 5 and the Two Adams

Paul identifies Adam as “a type of the one who was to come” and places the disobedience of the first Adam in direct contrast with the obedience of Christ:

“As one trespass led to condemnation for all men, so one act of righteousness leads to justification and life for all men. For as by the one man’s disobedience the many were made sinners, so by the one man’s obedience the many will be made righteous.” —Romans 5:18–19

The parallel is federal and covenantal. Adam’s one disobedience is imputed to those he represented, bringing condemnation and death. Christ’s obedience is imputed to those he represents, bringing justification and life. Romans 5 therefore reveals the legal architecture of the Covenant of Redemption.

The Covenant of Redemption and the Divine Decree

The Covenant Is Not Merely Another Name for the Decree

An objection sometimes raised is that the Covenant of Redemption appears to add nothing to the eternal decree of God. The two are closely related, but they should not be identified without remainder. The decree emphasizes God’s sovereign determination of all things. The covenantal formulation reveals the personal, representative, legal, and promissory structure of the Son’s mission.

The doctrine may be considered in two phases.

The Eternal Purpose

The first phase is God’s eternal decree. Election is in Christ before the foundation of the world, as Ephesians 1:4 teaches. Second Timothy 1:9 likewise says that God’s saving purpose and grace were given to us in Christ before the ages began. Election is therefore not an abstract decree concerning isolated individuals; it is election in the God-man who was appointed as their federal head and redeemer.

Historical Manifestation and Execution

The second phase is the manifestation and execution of the eternal purpose in the incarnate life of Christ. First Peter 1:20 says that Christ was foreknown before the foundation of the world and then manifested in the last times for the sake of his people.

The eternal plan hidden in God is realized in Christ Jesus. The Gospels therefore portray Jesus as carrying out a mission previously given to him. The Father repeatedly sends the Son, and Jesus repeatedly explains the purpose for which he came into the world. Everything he teaches and does belongs to the work the Father gave him. His miracles are not independent acts but manifestations of the Father’s work through the Son.

This historical obedience shows why the Covenant of Redemption is more than a bare decree. The decree takes covenantal form in the incarnate Son’s obedient mission, representative work, sacrificial death, resurrection, and exaltation.

The Foundation of the Covenant of Grace

The Covenant of Redemption is the foundation of the Covenant of Grace. Christ first secures the inheritance through his obedience; he then gives that inheritance to his people through the Covenant of Grace.

At the Last Supper, Jesus declares that the cup is the new covenant in his blood. In the same setting he tells the disciples that he confers a kingdom upon them as the Father conferred a kingdom upon him (Luke 22:19–20, 29). The kingdom given to Christ under the Covenant of Redemption becomes the kingdom bestowed upon believers under the Covenant of Grace.

If the Covenant of Grace is a genuine covenantal administration of the benefits Christ purchased, then the eternal arrangement that grounds it should not be reduced to an impersonal decree. The Covenant of Grace presupposes Christ’s prior covenantal undertaking.

The Covenant of Redemption and the Doctrine of the Trinity

A covenant ordinarily involves distinct parties and distinct acts of willing. This may appear to imply three independent centers of consciousness or three divine wills. Such a conception would divide the divine essence and lead toward tritheism or an eternal subordination of the Son.

The answer requires the classical distinction between God’s life ad intra and his works ad extra.

Relations of Origin Ad Intra

The persons are eternally distinguished by relations of origin. The Father is unbegotten. The Son is eternally begotten of the Father. The Holy Spirit eternally proceeds from the Father and the Son. These personal distinctions are real, but they do not divide the one divine essence.

Inseparable Operations Ad Extra

All of God’s outward works are works of the one triune God. Creation is not the work of the Father alone, redemption is not the work of the Son alone, and sanctification is not the work of the Spirit alone. Each person acts in every external work according to his personal mode of subsistence.

Scott Swain summarizes the doctrine: because the three persons are one God, each person is operative in every external work of God, from creation through redemption to consummation. The operations are inseparable because the divine essence, power, knowledge, and will are one.

This doctrine does not erase the personal missions. The Father sends the Son; the Son assumes human nature and obeys as mediator; the Father and the Son send the Spirit; and the Spirit applies Christ’s accomplished redemption. The one divine action has a trinitarian order.

One Divine Will, Personally Expressed

Vos’s language about the “will of the Father” and the “will of the Son” must be understood carefully. It does not refer to two separate divine faculties capable of disagreement. It refers to the one divine will personally expressed by the Father and personally expressed by the Son.

The first person expresses the one divine will as Father, the one who sends and gives the elect to the Son. The second person expresses the same divine will as the eternally begotten Son, who willingly undertakes the mission of mediator. The third person expresses the same divine will as the Spirit who proceeds from the Father and the Son and is sent to unite the elect to Christ.

The Covenant of Redemption may therefore be defined as the eternal agreement of the three persons, according to their personal relations, that the Son would be sent to accomplish redemption and the Spirit would be sent to apply it. This is not negotiation among three gods. It is the personal, ordered expression of the one indivisible purpose and will of the triune God.

Q&A

How Should Vos’s Reference to Two “Wills” Be Understood?

Vos is not teaching two independent divine wills. His language concerns the one divine will in its distinct personal expression as the Father gives the elect to the Son and as the Son presents himself as their surety. Because Father and Son share the same undivided divine essence, disagreement between them is impossible.

What about Christ’s Prayer in Gethsemane?

Jesus prays:

“Father, if you are willing, remove this cup from me. Nevertheless, not my will, but yours, be done.” —Luke 22:42

Here the distinction is not between the Father’s divine will and a contrary divine will in the Son. The incarnate Son possesses both the divine nature and a complete human nature, including a true human will. In Gethsemane his sinless human will naturally recoils from the horror of bearing divine wrath, yet he freely and perfectly submits that human will to the Father.

The reality of this obedience is essential to salvation. Christ did not merely appear to struggle or obey. As true man and second Adam, he underwent genuine testing and rendered the human obedience Adam failed to give.

Could Christ Have Sinned?

The doctrine of Christ’s impeccability requires several affirmations. According to his divine nature, sin was impossible. God cannot deny himself, and the one divine will cannot become opposed to itself.

According to his human nature, Christ possessed a true human will and was genuinely tempted. His temptations were not illusory. Yet his human nature never existed as an independent human person. It was inseparably united to the eternal Son in the hypostatic union. The person who acted was the divine Son incarnate. Christ was therefore impeccable as a person, even though his obedience as man was real and costly.

This mystery protects both sides of biblical teaching: Christ is fully divine and incapable of sin, and he is fully human, genuinely tested, and truly obedient.

Why Does Christ’s True Human Will Matter?

The early heresy of Apollinarianism taught that the divine Logos replaced the rational human soul in Christ. That would mean Christ did not assume a complete humanity. The church rejected this view because what is not assumed is not healed. To redeem human beings, Christ had to possess a true body, rational soul, mind, affections, and will.

Later controversy distinguished the orthodox doctrine of two wills from monothelitism, the claim that Christ has only one will. Because Christ has two complete natures, he has the divine will common to the Trinity and a true human will. His human obedience is the obedience of the second Adam rendered in our nature and on our behalf.

Is the Covenant of Redemption Compatible with Universal Atonement?

A theologian could use the expression while redefining its content, but the classic Reformed doctrine is intrinsically definite. The Father gives a particular people to the Son; the Son undertakes to redeem that people; and the Spirit applies redemption to the same people. John 6 and John 17 emphasize that Christ saves all whom the Father has given him and loses none of them.

A hypothetical universalist arrangement, in which Christ merely makes salvation possible for every person on condition of faith, would be a substantially different doctrine. It would lack the identity between election, redemption, and effectual application that belongs to the Reformed Covenant of Redemption.

Was Christ Mediator for Old Testament Believers before the Incarnation?

Yes, in the sense that the benefits of his future work were applied to believers before the work was historically accomplished. Christ was appointed mediator in the eternal purpose of God, and his sacrifice was certain. Old Testament saints were justified, regenerated, and preserved on the credit of the redemption he would later accomplish.

This does not mean that the pre-incarnate Son had already assumed human nature. The Logos asarkos, the Word considered before the incarnation, had not yet become man. Nevertheless, the efficacy of his appointed mediation reached backward because God’s promise could not fail.

What Is the Communication of Attributes?

The communicatio idiomatum concerns the way Scripture predicates properties of either nature of the one person of Christ. Acts 20:28 can speak of God purchasing the church “with his own blood.” Blood belongs to Christ’s human nature, yet the subject who shed it is the person of the divine Son. Similarly, Mary may be called Theotokos, the God-bearer, not because she originated the divine nature but because the person born from her is God the Son incarnate.

The Reformed tradition does not teach that the attributes of one nature are transferred ontologically to the other. Christ’s humanity does not become omnipresent or infinite. Rather, the properties of either nature may be truly predicated of the one person according to the appropriate nature.

How Does the Covenant of Redemption Encourage Believers?

The doctrine directs assurance away from the instability of human performance and toward the eternal purpose of the triune God. Salvation is not an improvised response to sin. The Father chose a people in Christ, the Son willingly became their surety and accomplished their redemption, and the Spirit infallibly applies that redemption.

Believers also possess a sympathetic high priest. The Son who undertook the covenant entered our weakness, endured temptation, obeyed through suffering, and passed through death. Because he was tested without sin, Christians may draw near to the throne of grace with confidence.

“We do not have a high priest who is unable to sympathize with our weaknesses, but one who in every respect has been tempted as we are, yet without sin.” —Hebrews 4:15

Conclusion

The Covenant of Redemption is the eternal foundation of the gospel. The Father gives the elect to the Son and appoints him their head and surety. The Son willingly assumes human nature, places himself under the law, fulfills all righteousness, bears the curse, and merits eternal life. The Father raises and exalts him, gives him the nations, and grants him the Spirit to pour out upon the church. The Spirit applies the Son’s finished work to every person for whom he acted.

The doctrine therefore holds together election, incarnation, active obedience, atonement, resurrection, ascension, Pentecost, perseverance, and glorification. It shows that the salvation of the church is the unified work of the Father, Son, and Holy Spirit and that the purpose of the triune God cannot fail.
