Sinlessness of Jesus
“For our sake he made him to be sin who knew no sin, so that in him we might become the righteousness of God.”
Definition
The sinlessness of Jesus is the fact, attested throughout the New Testament, that Christ never sinned, in thought, word, or deed. This is a claim about what actually occurred in his life — distinct from impeccability, the further claim that he could not have sinned even if tempted. Jesus himself challenged his critics on this point: “Can any of you prove me guilty of sin?” (John 8:46).
Confessional Definition
The 1689 Second London Baptist Confession states that the Son of God took “man’s nature, with all the essential properties and common infirmities of it, yet without sin.”1
Biblical Basis
Hebrews describes Christ as one who “has been tempted in every way, just as we are — yet was without sin” (Heb. 4:15), “a high priest who meets our need — one who is holy, blameless, pure, set apart from sinners” (Heb. 7:26), offering himself to God “unblemished” (Heb. 9:14). Peter, who knew Jesus personally, testifies that he “committed no sin, and no deceit was found in his mouth” (1 Pet. 2:22). John states it categorically — “in him is no sin” (1 John 3:5) — and Paul grounds the whole logic of the atonement in it: God “made him to be sin who knew no sin, so that in him we might become the righteousness of God” (2 Cor. 5:21).
Objections and Responses
If Christ was truly, perfectly sinless, how could God justly treat him as bearing the guilt of sin and punish him for it — isn’t punishing the innocent an act of injustice? Hodge calls this a “moral objection” resting on the axiom that “the innocent cannot be guilty,” so that treating a sinless person as guilty would require God either to be mistaken about the facts or to act unjustly. His answer is that Scripture’s own teaching settles the question apart from the philosophical axiom: “if the Bible teaches that the innocent may bear the guilt of the actual transgressor… then it is in vain to say that this cannot be done.” Hodge also notes that the underlying principle — one party justly bearing consequences incurred by another, within a representative relationship — is not unique to the atonement but “carried out in providence” throughout Scripture and ordinary human experience (e.g., Exod. 20:5).2
