A Reformed Exegetical & Theological Rebuttal

A Reformed rebuttal to the claim that 1 Peter 3:18–22 collapses TULIP

Far from dismantling the doctrines of grace, 1 Peter 3:18–22 is one of the richest soteriological texts in the New Testament precisely because it teaches effectual substitutionary atonement, locates saving power in Christ’s resurrection rather than in water, and employs the Noah typology in ways that reinforce every point of TULIP. The assertion that this passage “does not allow any part of the TULIP of Calvinism to be true” rests on a superficial reading that ignores Peter’s own qualifying clause, misunderstands the Reformed distinction between sign and thing signified, and commits the very hermeneutical error it accuses Calvinists of committing — namely, importing an external theological framework (baptismal regeneration and universal atonement) into a text that, on close examination, teaches neither. What follows is a detailed exegetical and theological rebuttal drawing from Reformed sources spanning five centuries.

⚠ The Critic’s Errant Claim

“1 Peter 3:18-22 does not allow any part of the TULIP of Calvinism to be true. The passage supports baptismal regeneration and causes justification by faith alone to collapse. In addition, the passage supports an atonement made once for all people. All of this makes TULIP collapse. Ideology external to the passage, and other passages of Scripture have to be brought into the text in order to prop up TULIP since the text itself does not support it.”

Exegesis of Verse 21

Peter himself denies that the physical rite of baptism saves

The linchpin of the anti-Calvinist argument is the clause “baptism now saves you” in verse 21. Taken in isolation, this appears to support baptismal regeneration. But Peter immediately appends a parenthetical qualification that the critic’s argument entirely overlooks: “not the removal of dirt from the flesh, but the appeal of a good conscience toward God — through the resurrection of Jesus Christ.” Peter explicitly negates the idea that the outward, physical act of water baptism is the mechanism of salvation.

John Calvin

“When Peter, having mentioned baptism, immediately made this exception, that it is not the putting off of the filth of the flesh, he sufficiently shewed that baptism to some is only the outward act, and that the outward sign of itself avails nothing.” Calvin further insisted that Peter “intended to set forth the effect of baptism, that no one might glory in a naked and dead sign, as hypocrites are wont to do.”

The saving efficacy is located not in the water but in Christ’s resurrection — an objective, historical, extra nos reality received by faith. Peter’s own words thus function as an internal refutation of baptismal regeneration before any external passage need be consulted.^[1]

◆ Key Greek Term

The Greek term ἐπερώτημα (eperōtēma), which Peter uses to describe what baptism actually is, further undermines the baptismal regeneration reading. This word — a hapax legomenon in the New Testament — carries the lexical range of “appeal,” “pledge,” or “answer.” Whether one translates it as “the appeal to God for a good conscience” (ESV, NASB) or “the pledge of a good conscience toward God” (NIV, CSB), the result is the same: what saves is the inward reality of faith directed toward God, not the outward administration of water.

John Gill

“The design of baptism is not to take off the sordid flesh … or to take away either original or actual sin; this only the blood of Christ can do.” Gill further noted that baptism “rightly performed, and its end answered,” occurs “when a person, conscious to himself of its being an ordinance of Christ, and of his duty to submit to it, does so with a pure conscience.”

“Does this outward washing with water itself wash away sins?” — “No, only Jesus Christ’s blood and the Holy Spirit cleanse us from all sins.”

Sacramental Theology

The sign and the thing signified: how Reformed sacramental theology reads “baptism saves”

The critic’s argument depends on collapsing the distinction between the sacramental sign (water baptism) and the thing signified (union with Christ through faith). But this distinction is the cornerstone of Reformed sacramental theology, codified in every major Reformed confession.

“There is, in every sacrament, a spiritual relation, or sacramental union between the sign and the thing signified: whence it comes to pass, that the names and effects of the one are attributed to the other.”

— Westminster Confession of Faith, 27.2

This principle — called “sacramental union” — explains precisely how Peter can say “baptism saves” without teaching that water regenerates. The sign bears the name of the reality it signifies. When Scripture says baptism saves, it employs the same metonymic language found in Genesis 17:10, where circumcision “is” the covenant, and in 1 Corinthians 5:7, where Christ “is” the Passover lamb. No one supposes Paul taught that Christ is literally a sheep; likewise, no one who understands sacramental language need suppose Peter taught that water literally regenerates.^[3]

×(Westminster Confession of Faith, 27.2; Derek Thomas, “Why Does 1 Peter 3:21 Say Baptism ‘Saves You’?,” Ligonier Ministries)

John Calvin (Institutes)

“Moreover, when we speak of sacraments, two things are to be considered, the sign and the thing itself. In baptism the sign is water, but the thing is the washing of the soul by the blood of Christ and the mortifying of the flesh.”

He warned against two equal and opposite errors — tearing the sign from the thing signified (as if sacraments were empty rituals) and confusing them (as if the sign itself possessed saving power).

Francis Turretin

Sacramental efficacy is “relative and moral” rather than physical or causal: “A twofold efficacy is ascribed to the sacraments according to us: the one moral and objective … the other covenantal, by which God, sealing by the sacraments his promise or covenant, confers the very things promised upon the believing soul.”

Herman Bavinck

“The sacrament does not impart one benefit that is not also received from the Word of God by faith alone; the content of both is identical.”

The Analogy

On this understanding, baptism is God’s visible word — a divine pledge and seal that confirms to faith what Christ has accomplished, but which operates only through the Spirit’s application received by faith. The physical water is not the agent of salvation any more than the ink on a marriage certificate is the agent of love.^[4]

×(John Calvin, Institutes of the Christian Religion, IV.xv–xvi; Francis Turretin, Institutes of Elenctic Theology, Topic XIX; Herman Bavinck, Reformed Dogmatics, vol. 4)

“Grace and salvation are not so inseparably annexed unto it, as that no person can be regenerated or saved without it; or, that all that are baptized are undoubtedly regenerated.”

— Westminster Confession of Faith, 28.5

The Belgic Confession, Article 34, teaches explicitly that salvation “does not happen by the physical water but by the sprinkling of the precious blood of the Son of God.” The 1689 London Baptist Confession restricts baptism to those who “actually profess repentance towards God, faith in, and obedience to, our Lord Jesus Christ,” presupposing that faith precedes and qualifies the rite. Every stream of the Reformed tradition — Presbyterian, Continental Reformed, and Baptist — denies that the physical act of baptism regenerates. The claim that 1 Peter 3:21 “supports baptismal regeneration” thus requires not only overriding Peter’s own parenthetical denial but overriding the entire Reformed confessional tradition and the broader canonical witness.^[5]

Sola Fide

How the passage is consistent with justification by faith alone

The assertion that 1 Peter 3:18–22 “causes justification by faith alone to collapse” confuses the instrumental role of faith with the confirmatory role of sacraments. In Reformed soteriology, faith is the sole instrument of justification — the empty hand that receives Christ’s imputed righteousness. Sacraments are means of grace that confirm, strengthen, and seal what faith has already received. These are not competing instruments but complementary realities operating at different levels.

R.C. Sproul

The word “by” in “justified by faith” describes the means by which justification comes to the sinner, and that means is trust in Christ alone — “which trust is evidenced by our humble request for God’s forgiveness based on Christ’s work and promise, that saves us.” Baptism is “a visible sign and seal of our union with Christ,” and “our faith, whether it comes before, during, or after the ceremony of baptism itself, alone unites us with Jesus.”

^[6]

×(R.C. Sproul, Faith Alone; R.C. Sproul, “What Is Baptism?,” Crucial Questions series)

…buried with him in baptism, in which you were also raised with him through faith in the powerful working of God, who raised him from the dead. — Colossians 2:12

The parallel passage in Colossians 2:12 provides the decisive canonical commentary. The phrase “through faith” is Paul’s own inspired gloss on what the baptism-resurrection connection means.

◆ The Decisive Proof

As Lane Keister noted, “The power of baptism cannot lie in the sign. This is proven absolutely, 100% conclusively by Romans 4:11, which states explicitly that Abraham already had the thing signified long before he ever had the sign applied to him.” Abraham was justified by faith in Genesis 15:6, yet did not receive circumcision until Genesis 17 — demonstrating that the sign follows the reality, not the reverse. The case of Cornelius in Acts 10:44–48 confirms this order in the new covenant: the Holy Spirit fell on Cornelius and his household before water baptism was administered.

Charles Hodge

“He who exercises repentance towards God and faith in our Lord Jesus Christ is in a state of salvation before baptism and therefore in a state of regeneration. Regeneration consequently precedes baptism, and cannot be its effect.”

James White similarly pointed to Cornelius as proof that “we know that they were saved before being baptized because they had received the Holy Spirit, which is the evidence of salvation.” Far from collapsing sola fide, 1 Peter 3:21 — read with Peter’s own qualification and with the analogia fidei — presupposes it.^[7]

×(Charles Hodge, Systematic Theology, vol. III; James R. White, “A Brief Rebuttal of Baptismal Regeneration”; Lane Keister, “Sign, Thing Signified, and Sacramental Relationship”; cf. Colossians 2:12; Romans 4:11; Acts 10:44–48)

Greek Exegesis

The Greek text of 1 Peter 3:21 confirms the Reformed reading

◆ ἀντίτυπον (antitypon)

The Greek word ἀντίτυπον (antitypon) in verse 21 is crucial. It means “antitype” or “corresponding thing” — that which answers to a prior type. In the NA28 text (ὄ καὶ ὑμᾶς ἀντίτυπον νῦν σᾧζει βάπτισμα), the word functions adjectivally, modifying βάπτισμα (“baptism”). The relative pronoun ὄ (neuter singular) has its antecedent in ὕδατος (“water”) from verse 20, creating the grammatical chain: the flood waters were the type; baptism is the antitype.

But a type-antitype relationship establishes correspondence, not identity. The antitype points to and participates in a greater reality without being that reality in itself. As R.T. France observed, “The essential principle of New Testament typology is that God works according to a regular pattern, so that what he has done in the past can be expected to find its counterpart in his work in the decisive period of the New Testament.” Baptism corresponds to Noah’s flood as sign corresponds to reality — it does not mechanically produce what it signifies. The same word appears in Hebrews 9:24, where the earthly tabernacle is called the ἀντίτυπον of the heavenly reality — and no one supposes the earthly tabernacle was heaven.^[8]

×(Daniel B. Wallace, Greek Grammar Beyond the Basics; Wayne Grudem, 1 Peter, Tyndale New Testament Commentary; R.T. France, Jesus and the Old Testament)

◆ The μέν … δέ Construction in Verse 18

The phrase σαρκὶ μὲν … πνεύματι δέ (“put to death in the flesh but made alive in the spirit”) employs the classical μέν … δέ correlative construction, establishing a contrast between two spheres or modes of existence. The anarthrous datives (lacking the article) function as datives of reference or sphere: Christ was put to death with respect to his earthly, mortal mode of existence but made alive with respect to the eschatological, Spirit-empowered mode. This parallels Romans 1:3–4, where Christ is “descended from David according to the flesh” (κατὰ σάρκα) and “declared to be the Son of God in power according to the Spirit of holiness” (κατὰ πνεῦμα ἁγιωσύνης) through the resurrection.

John Calvin

“We then cannot otherwise derive benefit from baptism, than by having all our thoughts fixed on the death and the resurrection of Christ.”

The theological significance is that Christ’s resurrection — His transition from the σάρξ-sphere to the πνεῦμα-sphere — is the basis of baptism’s saving significance (v. 21: “through the resurrection of Jesus Christ”). The saving power is anchored in Christ’s completed work, not in sacramental water.^[9]

×(John Calvin, Commentary on the Catholic Epistles, on 1 Peter 3:21; J. Ramsey Michaels, 1 Peter, Word Biblical Commentary; Karen Jobes, 1 Peter, Baker Exegetical Commentary)

Definite Atonement

“The righteous for the unrighteous” teaches effectual substitution, not universal atonement

The assertion that 1 Peter 3:18 “supports an atonement made once for all people” misreads the passage at multiple levels.

◆ Substitutionary Language

The phrase δίκαιος ὑπὲρ ἀδίκων (“the righteous for the unrighteous”) is substitutionary language of the most precise kind. The preposition ὑπέρ (hyper) with the genitive carries the meaning “on behalf of” and, in soteriological contexts, extends to “in the place of” — a substitutionary sense confirmed by parallel usage in 2 Corinthians 5:21, Galatians 3:13, and by the cognate ἀντί (anti, “in the place of”) in Mark 10:45 and 1 Timothy 2:6. The singular δίκαιος standing over against the plural ἀδίκων echoes Isaiah 53:11 LXX, where the “righteous one” (δίκαιον) “shall justify many.” This is personal, definite, penal substitution: Christ stood in the precise legal place of specific sinners and bore their penalty.

Thomas Schreiner

“Peter, drawing on Isaiah 53, declares … ‘For Christ also suffered for sins once for all, the righteous for the unrighteous, that he might bring you to God.’ Penal substitution captures the heart of the atonement, for we see in the atoning sacrifice of Christ both the love and justice of God.”^[10]

×(Thomas Schreiner, “Penal Substitutionary Atonement,” The Gospel Coalition; cf. 1 Peter 2:24; Isaiah 53:4–6, 11)

The adverb ἅπαξ (hapax, “once” or “once for all”) underscores the decisive, unrepeatable, and therefore effectual nature of Christ’s death. This word — shared with Hebrews 7:27, 9:26–28, and 10:10 — denotes an action of perpetual validity that needs no repetition. But the critic’s claim that “once for all” means “once for all people” confuses sufficiency with intent. The Reformed position, classically articulated by the Synod of Dort, is that Christ’s death is sufficient for all but efficient for the elect. The word ἅπαξ modifies the verb “suffered” and qualifies the manner of Christ’s death (a single, decisive act), not the scope of its intended beneficiaries. The scope is determined by the purpose clause that follows.^[11]

×(Canons of Dort, Second Head of Doctrine, Articles 3–8; B.B. Warfield, The Plan of Salvation)

The Purpose Clause

The purpose clause ἵνα ὑμᾶς προσαγάγῃ τῷ θεῷ (“that He might bring you to God”) is the decisive grammatical indicator. The conjunction ἵνα introduces a purpose clause with the aorist active subjunctive (προσαγάγῃ), expressing Christ’s definite intention in suffering. The verb προσάγω means “to bring to, to lead into the presence of” — used in antiquity for introducing someone to an audience with a king. Christ suffered in order to actually bring specific people to God. The critical question for the atonement debate is whether this purpose succeeds. If Christ died to bring people to God, and some for whom He died are never brought to God, then either God’s purpose failed or Christ’s work was insufficient. Reformed theology denies both.

John Owen (The Death of Death)

“God imposed his wrath due unto, and Christ underwent the pains of hell for, either all the sins of all men, or all the sins of some men, or some sins of all men. If the last, some sins of all men, then have all men some sins to answer for, and so shall no man be saved. If the first, why then are not all freed from the punishment of all their sins?” The only coherent option is that Christ bore all the sins of some — the elect — and that His purpose in dying is effectually accomplished for every one of them.^[12]

×(John Owen, The Death of Death in the Death of Christ, Book I, ch. 3; J.I. Packer, “Introductory Essay” to Owen’s Death of Death)

Moreover, the phrase “the righteous for the unrighteous” does not say “the righteous for all the unrighteous” or “for every individual without exception.” It describes a category — Christ, the righteous one, died as substitute for unrighteous ones. The identity of those unrighteous ones is determined by the broader biblical theology of election and covenant.

Roger Nicole

“Particular redemption is an inevitable implicate of a recognition of the penal substitutionary nature of the atonement,” for “if we want to avoid the shoals of outright universalism, definiteness involves that the work of Christ was intended to terminate redemptively upon a part only of mankind, variously named His people, His Church, His body, His sheep, the elect.”

Owen further demonstrated that Christ’s sacrifice and intercession share the same objects: those for whom Christ died are those for whom He intercedes, and John 17:9 shows Christ explicitly limits His intercession — “I am not praying for the world but for those whom you have given me.”

B.B. Warfield

“The things we have to choose between are an atonement of high value, or an atonement of wide extension. The two cannot go together.”

The substitutionary language of 1 Peter 3:18, far from refuting definite atonement, is among its strongest supports.^[13]

The Five Points

How 1 Peter 3:18–22 positively supports every point of TULIP

The claim that this passage collapses TULIP can be turned on its head: each of the five points finds textual support within these very verses.

Total Depravity

Total Depravity is implied in the contrast between “the righteous” (singular — Christ alone) and “the unrighteous” (plural — humanity as a category). The term ἄδικος (adikos) means “falling short of the righteousness required by divine law.” That a sinless substitute was necessary demonstrates that sinners are entirely incapable of satisfying God’s justice themselves. The background of the flood narrative intensifies this: Genesis 6:5 states that “every intention of the thoughts of his heart was only evil continually,” and Genesis 8:21 repeats the diagnosis even after the flood, confirming that depravity is the permanent condition of fallen humanity, not a peculiarity of one generation. The flood generation’s universal rebellion, to which Peter alludes in verse 20, illustrates the Reformed doctrine that apart from grace, all human beings are dead in sin and unable to save themselves.^[14]

×(John Calvin, Commentary on Genesis 6:5; Jonathan Edwards, Original Sin; Steven Lawson, The Doctrines of Grace in John)

Unconditional Election

Unconditional Election is embedded in the phrase “a few, that is, eight souls, were brought safely through water” (v. 20). Peter’s emphasis on the smallness of the number — he specifies “a few” and then narrows it further to “eight” — mirrors the consistent biblical pattern of God saving a remnant by sovereign choice. Noah’s salvation was not earned by superior merit; Genesis 6:8 states that “Noah found grace in the eyes of the LORD.” The Hebrew word chēn (חֵן, “grace” or “favor”) indicates unmerited divine goodness.

John Calvin

“What happened in the age of Noah would always be the case, that mankind would rush on to their own destruction, but that the Lord would in a wonderful way deliver His very small flock.”

Charles Spurgeon

“The LORD shut him in” (Gen. 7:16) — God Himself sealed the door, not Noah. Only those whom God placed inside were saved; those outside perished without exception.

The ark itself typifies Christ — God’s appointed vessel of salvation — and those placed in the ark represent those whom God has elected and placed “in Christ.” This is unconditional election typified in Old Testament narrative.^[15]

×(John Calvin, Commentary on the Catholic Epistles, on 1 Peter 3:20; Charles Spurgeon, Sermon #823, “Noah’s Flood”; R.C. Sproul, Chosen by God)

Definite Atonement (Limited in Scope, Unlimited in Power)

Definite Atonement has been addressed extensively above. The substitutionary ὑπέρ, the effectual purpose clause (ἵνα … προσαγάγῃ), the ark saving only those inside, and Owen’s trilemma all converge on the conclusion that Christ’s death was designed to actually accomplish salvation for a definite people, not to make salvation merely possible for everyone.

Charles Spurgeon

“We hold that Christ, when He died, had an object in view, and that object will most assuredly, and beyond a doubt, be accomplished. We measure the design of Christ’s death by the effect of it.”

J.I. Packer

The purpose of the doctrine of particular redemption “is to safeguard the central affirmation of the gospel — that Christ is a redeemer who really does redeem.”^[16]

×(Charles Spurgeon, “Particular Redemption,” 1858; J.I. Packer, “Introductory Essay” to Owen’s Death of Death; D.A. Carson, “On Definite Atonement,” in The Glory of the Atonement)

Irresistible Grace

Irresistible Grace appears in the purpose clause “that He might bring us to God.” The verb προσάγω is active — Christ brings His people. He does not merely make an offer and wait; He effectually accomplishes the bringing.

Joel Beeke

“The good news of Christ’s definite atonement is that it means He is a complete Mediator. He both merits and applies salvation. Both are necessary because we are unable to do either. Christ must be a full Savior because sinners are spiritually dead and cannot independently receive a Christ presented to them. He must do everything — both the meriting and the applying.”

Charles Spurgeon

God said “Come into the ark” (Gen. 7:1), and Spurgeon observed that God said “come” rather than “go” — “plainly implying that God was Himself in the ark, waiting to receive Noah and his family.” God did not merely offer the ark as an option; He effectually drew Noah and his household into it and sealed the door behind them.^[17]

×(Joel Beeke, Living for God’s Glory; Charles Spurgeon, Sermon #3042, “The Parable of the Ark”; Sinclair Ferguson, The Holy Spirit, on effectual calling)

Perseverance of the Saints

Perseverance of the Saints is typified by the ark preserving all eight souls through the waters of judgment. Peter’s word choice is significant: διεσώθησαν δι᾿ὕδατος — “they were brought safely through water.” The eight were not merely rescued from judgment but preserved through it — the waters rose around them, yet they emerged alive on the other side. Not one of the eight perished in the ark.

Charles Spurgeon

“The ark had no harbor to go to, and we never read that Noah called up Shem, Ham, and Japheth to work at the pumps, nor yet that they had any, for there was not a leak in her. Those who are in Christ are sheltered from every storm; they shall never perish, neither shall any pluck them out of his hands.”

The passage concludes with Christ’s exaltation “at the right hand of God, with angels, authorities and powers in submission to him” (v. 22). The risen, ascended Christ who holds all authority in heaven and earth is the guarantor of His people’s final salvation. No power — angelic, demonic, or human — can overthrow Him or pluck His redeemed from His hand. The ark preserved all inside without exception; Christ preserves all who are in Him without exception.^[18]

Hermeneutics

Scripture interpreting Scripture is not “importing ideology” but the Bible’s own hermeneutic

The critic charges that “ideology external to the passage, and other passages of Scripture have to be brought into the text in order to prop up TULIP.” This charge reveals a fundamental misunderstanding of the Reformed hermeneutical principle of the analogia fidei — the analogy of faith — which holds that Scripture, as the unified Word of one divine Author, interprets itself.

“The infallible rule of interpretation of Scripture is the Scripture itself: and therefore, when there is a question about the true and full sense of any Scripture (which is not manifold, but one), it must be searched and known by other places that speak more clearly.”

— Westminster Confession of Faith, 1.9

This principle is not an alien grid imposed on the Bible; it is derived from the Bible’s own self-attestation as a coherent, non-contradictory divine revelation. Richard Muller, in his magisterial Post-Reformation Reformed Dogmatics, demonstrated that the Protestant orthodox employed the analogia fidei not as speculative philosophy but as “the use of a general sense of the meaning of Scripture, constructed from the clear or unambiguous loci, as the basis for interpreting unclear or ambiguous texts.” Reading 1 Peter 3:21 in light of Romans 3:28, Ephesians 2:8–9, Titus 3:5, and Colossians 2:12 is not eisegesis — it is the practice of letting clearer passages illuminate more ambiguous ones, which is the very method Scripture itself demands.^[19]

×(Westminster Confession of Faith, 1.9; Richard A. Muller, Post-Reformation Reformed Dogmatics, vol. 2; Charles Hodge, Systematic Theology, vol. I, on the unity of Scripture)

The presuppositionalist tradition within Reformed theology further exposes the naïveté of the critic’s charge. Cornelius Van Til argued that “there is no neutral ground” between Christian and non-Christian interpretive frameworks — every reader approaches a text with presuppositions that shape their conclusions. Greg Bahnsen defined a worldview as “a network of presuppositions in terms of which every aspect of man’s knowledge and awareness is interpreted.” The claim to read 1 Peter 3:18–22 “without ideology” is itself an ideological claim — it presupposes the autonomy of human reason, the neutrality of the interpreter, and the propriety of atomistic exegesis (treating each passage as a self-contained unit divorced from its canonical context). All three presuppositions are themselves theological commitments that the critic has imported into the text. K. Scott Oliphint, building on Van Til, noted that the unbeliever who claims interpretive neutrality operates on “borrowed capital” — using Christian assumptions about intelligibility, logic, and textual meaning while denying their Christian foundation. The Reformed reader, by contrast, brings to the text the Bible’s own teaching about itself: that it is the product of one divine Mind (2 Tim. 3:16; 2 Pet. 1:20–21), that it does not contradict itself, and that its clearer passages govern the interpretation of its more difficult ones. This is not “propping up” TULIP with external ideology; it is reading the Bible the way the Bible tells us to read the Bible.^[20]

×(Cornelius Van Til, The Defense of the Faith; Greg Bahnsen, Always Ready; K. Scott Oliphint, Covenantal Apologetics; John Frame, The Doctrine of the Knowledge of God)

⚠ The Critic’s Method Is Self-Refuting

It is worth noting that the critic’s own method is self-refuting. To claim that 1 Peter 3:18–22 “supports baptismal regeneration” requires importing a theological framework — one in which physical sacramental acts possess inherent saving power — that is nowhere stated in the text itself. Peter says “not the removal of dirt from the flesh”; the baptismal regenerationist must explain this away. To claim the passage “supports an atonement made once for all people” requires reading the word “all” into a text that never uses it — the passage says “the righteous for the unrighteous,” not “the righteous for all the unrighteous without exception.” The critic, in short, is doing the very thing he accuses Calvinists of doing: bringing a theological framework to the text. The only question is which framework is warranted by the whole counsel of God. The Reformed answer is that the framework of sovereign grace — articulated in the doctrines summarized by TULIP — is not imposed on Scripture but derived from it, refined across centuries of careful exegesis, and confirmed by the internal coherence of the biblical witness from Genesis to Revelation.^[21]

Verses 19–20

The “spirits in prison” and the broader exegetical context

Verses 19–20, in which Christ “went and proclaimed to the spirits in prison, because they formerly did not obey, when God’s patience waited in the days of Noah,” constitute one of the most debated passages in the New Testament. Martin Luther himself confessed uncertainty about its meaning. The two dominant Reformed interpretations are (1) that the pre-incarnate Christ preached through Noah by the Holy Spirit to the disobedient generation before the flood, who are now spirits in prison (held by Augustine, Calvin, Gill, Grudem, and many Reformers), and (2) that the risen Christ proclaimed His victory over fallen angelic beings associated with Genesis 6:1–4, who are now imprisoned (held by Schreiner and many modern exegetes). Wayne Grudem devoted a thirty-six-page appendix in his Tyndale commentary on 1 Peter to defending the first view, arguing that the “Spirit” (πνεύματι) by which Christ was “made alive” in verse 18 is the same Spirit through whom Christ “went and proclaimed” in verse 19 — connecting with 1 Peter 1:11, where “the Spirit of Christ” was active in the Old Testament prophets. Thomas Schreiner, by contrast, argued that “spirits” (πνεύματα) without qualification “usually refers to supernatural beings” in the New Testament, and that the verb “went” (πορευθείς) in verse 19 parallels the same verb in verse 22 (Christ’s ascension), suggesting a post-resurrection proclamation of triumph over demonic powers.^[22]

Neither Interpretation Helps the Critic

What matters for the present debate is that neither Reformed interpretation supports the critic’s case. On neither view does this passage teach a second chance for the dead, universal atonement, or baptismal regeneration. Both views reinforce the passage’s emphasis on divine sovereignty — whether in God’s patience toward the pre-flood generation while preparing salvation for the elect few, or in Christ’s triumphant authority over all spiritual powers.

Thomas Schreiner

“It makes no sense contextually for Peter to be teaching that the wicked have a second chance in a letter in which he exhorted the righteous to persevere and to endure suffering.”

The passage’s theological function, on any sound reading, is to encourage persecuted believers by assuring them that the Christ who suffered unjustly has been vindicated, exalted, and given authority over all powers — and that those who are united to Him by faith will likewise be brought safely through judgment, as Noah was brought safely through the flood.^[23]

Conclusion

The passage fortifies rather than falsifies the doctrines of grace

The assertion that 1 Peter 3:18–22 collapses TULIP cannot withstand exegetical scrutiny. Peter’s own qualifying clause (“not the removal of dirt from the flesh, but the appeal of a good conscience toward God”) explicitly guards against baptismal regeneration. The Greek term ἀντίτυπον establishes a typological correspondence between the flood and baptism that distinguishes sign from reality. The substitutionary language of δίκαιος ὑπὲρ ἀδίκων, combined with the effectual purpose clause (ἵνα … προσαγάγῃ τῷ θεῷ), teaches a definite atonement that actually accomplishes its intended goal. The Noah typology — eight souls preserved by sovereign grace through divine judgment — is a portrait of election, effectual calling, and perseverance. And the hermeneutical principle that Scripture interprets Scripture is not an external ideology but the Bible’s own prescribed method of reading, codified in every Reformed confession and defended on presuppositional grounds by Van Til, Bahnsen, and Oliphint.

The doctrines of grace do not need to be “propped up” by external ideology. They arise from the text of Scripture itself — this passage included — when that text is read in its full grammatical, historical, and canonical context.

The real interpretive error is not the Reformed practice of reading 1 Peter 3 alongside Romans 3, Ephesians 2, and Colossians 2; the real error is isolating five verses from the rest of divine revelation and then claiming that the isolated fragment overturns the whole. As Owen demonstrated, as Calvin taught, as the confessions codify, and as the Greek text confirms: Christ the righteous one suffered once, effectually, for the unrighteous whom He purposed to bring to God — and every one of them will arrive.
