Imputation

The theological tradition identifies three instances of imputation that together form the structure of redemption:

(1) The imputation of Adam's sin to humanity (Romans 5:12-19): "Therefore, just as sin came into the world through one man, and death through sin, and so death spread to all men because all sinned..." (5:12). The debate on eph' ho (ἐφ' ᾧ, "because all sinned" vs. "in whom all sinned") is technical, but 5:18-19 is clear: "as one trespass led to condemnation for all men... for as by the one man's disobedience the many were made sinners." Adam's transgression was legally constitutive for all who are "in Adam." This is not merely that all people follow Adam's example but that Adam's one act of disobedience brought condemnation upon all who are in him. Paul's point in the passage is the parallel: just as condemnation came through one man's representative act, so justification comes through one Man's representative act.

(2) The imputation of the believer's sin to Christ (2 Corinthians 5:21; Isaiah 53:4-6; 1 Peter 2:24): "He himself bore our sins in his body on the tree" (1 Peter 2:24); "the LORD has laid on him the iniquity of us all" (Isaiah 53:6). The sin of those who are "in Christ" was transferred to the account of Christ at the cross: he bore what was ours; his death paid what was our debt.

(3) The imputation of Christ's righteousness to the believer (Romans 5:17-19; Philippians 3:9; 2 Corinthians 5:21): "by the one man's obedience the many will be made righteous" (Romans 5:19); "not having a righteousness of my own that comes from the law, but that which comes through faith in Christ, the righteousness from God that depends on faith" (Philippians 3:9). The righteousness credited to the believer is not their own (produced by moral effort) but Christ's (received by faith and credited to their account).

2 Corinthians 5:21 is the most compressed statement of double imputation in the New Testament: "For our sake he made him to be sin who knew no sin, so that in him we might become the righteousness of God."

Four elements:

(1) "For our sake", the exchange is substitutionary and purposive. It was done pro nobis, for us, in our place, for our benefit.

(2) "He made him to be sin", not "sinful" (hamartolon) but "sin" (hamartia). The most concentrated theological expression of the transfer of the believer's sin to Christ. He did not become personally sinful; the guilt/penalty of sin was reckoned to his account and borne by him. The echoes of Isaiah 53 (asham, guilt offering, 53:10; the sin of many laid on him, 53:12) are audible.

(3) "Who knew no sin", the qualification that makes the exchange possible. If Christ were himself a sinner, his death would atone only for his own sin. The sinless life of Christ (Hebrews 4:15, 1 Peter 1:19 "a lamb without blemish or spot") is the precondition for his atoning death.

(4) "So that in him we might become the righteousness of God", the other side of the exchange. The believer does not merely receive forgiveness of sin (negative: debt cleared) but becomes the righteousness of God "in him", the positive credit of Christ's own righteous standing before the Father. This is justification's positive content: not merely acquittal but the crediting of an alien righteousness.

The Reformed tradition (particularly Calvin, Turretin, and the Westminster Standards) distinguishes two aspects of Christ's obedience that constitute the righteousness imputed to believers:

(1) Active obedience, Christ's lifelong perfect fulfillment of the law's moral demands on behalf of his people. "Just 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 5:19). The "obedience" of Christ is not only his death (passive, submitting to the law's penalty) but his perfect life (active, fulfilling the law's demands). What Adam failed to do, live in perfect covenant faithfulness, Christ accomplished.

(2) Passive obedience, Christ's submission to the law's penalty (death, curse) on behalf of sinners. "Christ redeemed us from the curse of the law by becoming a curse for us" (Galatians 3:13). He bore what the law demanded as punishment for transgression.

The distinction matters for the content of imputed righteousness: if only Christ's passive obedience (death) is imputed, believers receive forgiveness of sin but not positive righteousness, they stand in a neutral moral position, not a righteous one. The imputation of both active and passive obedience means believers receive not only cleared guilt but the positive righteous standing of the One who perfectly obeyed. Romans 5:17, "much more will those who receive the abundance of grace and the free gift of righteousness reign in life through the one man Jesus Christ."

Imputation is the mechanism that makes justification more than forgiveness. Forgiveness clears the debt; imputation credits a positive righteousness. The believer before the divine tribunal does not merely stand with a cleared record (zero balance) but with the righteous standing of the one who lived the only perfectly obedient human life. "In him", the two words that anchor everything. The righteousness that counts before YHWH is not produced by the believer's moral effort; it was earned by Christ's entire life and death and credited to the believer's account through faith-union with him.
