A 1689 Reformed Baptist Rebuttal
Far from dismantling the doctrines of grace, 1 Peter 3:18–22 is one of the most potent texts in all of Scripture for establishing them. The claim that this passage "collapses TULIP" rests on a superficial reading of the phrase "baptism…now saves you" (v. 21) — a reading that Peter himself immediately and explicitly qualifies, that the Greek text grammatically forbids, and that seventeen centuries of orthodox Christianity have rejected. When interpreted through the lens of 1689 Reformed Baptist covenant theology, with its insistence that the New Covenant consists exclusively of regenerate members and that baptism is an ordinance administered only to those who credibly profess faith, this passage becomes not merely compatible with Reformed soteriology but a powerful vindication of total depravity, unconditional election, definite atonement, irresistible grace, and the perseverance of the saints.
The following rebuttal demonstrates this from the Greek text, from the passage’s own internal logic, from the Noah typology Peter deliberately invokes, and from the theological framework of the Particular Baptist tradition that produced the Second London Baptist Confession of 1689.
The critic’s errant claim is: “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.”
Verse 21
The apostle Peter, under the inspiration of the Holy Spirit, anticipated the very misreading that baptismal regenerationists would later impose upon his words — and he preemptively destroyed it. In verse 21, having stated that "baptism doth also now save us," Peter immediately appends a qualifying clause that functions as an interpretive guardrail: "not the putting away of the filth of the flesh, but the answer of a good conscience toward God, by the resurrection of Jesus Christ." The Greek construction (οὐ σαρκὸς ἀπόθεσις ῥύπου) is an explicit, categorical denial that the physical application of water to the body produces any spiritual cleansing.
Call a man a Baptist, or a Presbyterian, or a Dissenter, or a Churchman, that is nothing to me — if he says that baptism saves the soul, out upon him, out upon him, he states what God never taught, what the Bible never laid down, and what ought never to be maintained by men who profess that the Bible, and the whole Bible, is the religion of Protestants.

Spurgeon elsewhere stated plainly: "Baptism without faith saves no one." The Second London Baptist Confession of Faith (1689), Chapter 29, paragraph 1, defines baptism as "an ordinance of the New Testament, ordained by Jesus Christ, to be unto the party baptized, a sign of his fellowship with him, in his death and resurrection; of his being engrafted into him; of remission of sins; and of giving up into God, through Jesus Christ, to live and walk in newness of life." The operative word is sign. As the framers of the Confession understood — men like Nehemiah Coxe, Benjamin Keach, William Kiffin, and Hercules Collins — a sign points to a reality beyond itself; it does not constitute that reality. Peter’s own denial clause proves that the apostle understood baptism exactly as the Particular Baptists later confessed it: as a sign of salvation, not the instrument of it.[1]
Greek Exegesis
Three Greek terms in this passage are decisive for understanding Peter’s meaning, and all three militate against baptismal regeneration. First, the word ἀντίτυπον (antitupon), rendered "figure" in the KJV and "corresponds to" in the ESV, identifies baptism as an antitype — a copy, counterpart, or representation that points to a greater spiritual reality. This word appears only twice in the New Testament: here and in Hebrews 9:24, where earthly realities are explicitly identified as copies (ἀντίτυπα) of heavenly ones. The lexical force of the term demands that baptism be understood as a picture or figure of salvation, not as salvation itself. As Rogers and Rogers note in their Linguistic Key to the Greek New Testament, "The saving by baptism Peter mentions here is symbolic not actual, as Peter hastens to explain."
Peter says that our baptism is an ἀντίτυπον to the baptism of Noah… we are not to cleave to the element of water, and that what is thereby typified flows from Christ alone.
there is something in these which correspond, and answer to, and bear a resemblance to each other...
Gill traced the analogy in detail — the ark was God’s ordinance (not man’s invention), the ark was scorned by men (as baptism is), and only adult persons entered the ark, just as only believers should be baptized.[2]
Second, the word ἐπερώτημα (eperōtēma), a hapax legomenon in the New Testament, is variously rendered "answer" (KJV), "appeal" (ESV), or "pledge" (NIV). Whether one takes it as the believer’s appeal to God for a clean conscience, or as a pledge of commitment made from a good conscience, both meanings presuppose the existence of inward faith prior to and independent of the water rite. Papyrological evidence from the ancient world shows that ἐπερώτημα was a technical term in contract law, denoting the pledge or undertaking given by one party in response to formal questions — implying the conscious, voluntary registration of agreement to terms. Peter is saying that baptism’s saving significance lies not in the water but in the conscious, faith-driven response of the person being baptized. Gill noted that the Latin Vulgate rendered this "the interrogation of a good conscience," possibly reflecting the early church practice of asking baptismal candidates formal questions ("Dost thou renounce Satan?
Dost thou believe in Christ?"), to which they gave conscious answers — something an unregenerate person or an infant is incapable of doing. Gill concluded: "the sense seems plainly this; that then is baptism rightly performed, and its end answered, when a person, conscious to himself of its being an ordinance of Christ, and of his duty to submit to it, does do so upon profession of his faith in Christ, in obedience to his command, and with a view to his glory; in doing which he discharges a good conscience towards God." Thomas Schreiner, in his 1, 2 Peter, Jude commentary, affirmed that "Peter did not focus on promises believers make when baptized but the saving work of Christ and his resurrection."[3]
Third, the phrase δίκαιος ὑπὲρ ἀδίκων (dikaios huper adikōn, "the righteous for the unrighteous") in verse 18 establishes the substitutionary and particular nature of Christ’s atoning work — the true ground of salvation to which baptism merely points. The singular δίκαιος identifies Christ as the uniquely Righteous One (echoing Isaiah 53:11 LXX, where the Servant is called δίκαιον). The preposition ὑπέρ denotes substitution — the Righteous One suffering in the place of the unrighteous.
The purpose clause that follows, ἵνα ὑμᾶς προσαγάγῃ τῷ θεῷ ("that he might bring us to God"), uses the verb προσάγω, a technical term for bringing someone into the presence of a king or into the inner courts of the temple, indicating that Christ’s death actually accomplishes — not merely makes possible — the reconciliation of sinners to God. This is the language of effectual, definite redemption, not of a hypothetical, universal provision.[4]
Baptist Ordinance Theology
The claim that 1 Peter 3:21 teaches baptismal regeneration collapses the moment one understands the distinction between a sign and the thing signified — a distinction that lies at the very heart of Reformed Baptist theology. The 1689 Second London Baptist Confession deliberately and systematically replaced every instance of the word "sacrament" found in the Westminster Confession of Faith with the word "ordinance." This was not a stylistic preference but a theological conviction. As the framers of the Confession understood, the term "sacrament" carried connotations — particularly in Roman Catholic usage — of an inherent capacity to convey saving grace (ex opere operato). The Particular Baptists rejected this root and branch.
Baptism is an ordinance of obedience that pictures gospel realities already accomplished in the believer by the sovereign work of the Holy Spirit; it does not convey, confer, or mediate the grace it signifies. Benjamin Keach, one of the signatories of the 1689 Confession and pastor of the Horsleydown church for thirty-six years, wrote in Gold Refin’d (1689) that baptism is "a lively Resemblance of Christ’s Death, Burial, and Resurrection," and he quoted the Puritan Stephen Charnock approvingly: "Outward Water cannot convey inward Life" and "it doth not work as a physical Cause upon the Soul." Keach affirmed that "Faith only is the Principle of spiritual Life."[5]
The Westminster Confession’s concept of "sacramental union" (WCF 27.2) — the principle that "the names and effects of the one are attributed to the other" — was deliberately omitted from the 1689 Confession. The Particular Baptists had a simpler and more biblically direct explanation for why Scripture sometimes attributes saving language to baptism: it is a figure of speech in which a sign receives the name of the thing it signifies, just as the bread of the Lord’s Supper is called "my body" without anyone supposing it to be literally Christ’s flesh. When Peter says "baptism now saves you," he is employing exactly this figure — attributing to the sign (the water rite) the properties of the thing signified (salvation through union with the crucified and risen Christ). The word ἀντίτυπον makes this explicit: baptism is the antitype, the corresponding figure, not the saving reality itself.
Baptism does not perform these things. It does not create within us a new heart. It does not bring us into union with Christ. Rather, it displays on the outside what God, in His sovereign grace, has already performed on the inside.
James White of Alpha and Omega Ministries has likewise argued that baptism is "an ordinance, given by Christ to His Church, in which the great and marvelous work of God in salvation is pictured for all to see" — not "mere symbol" but also emphatically not the cause or instrument of salvation.[6]
The 1689 Baptist framework provides a further and uniquely devastating argument against baptismal regeneration that no paedobaptist confession can make with equal force. Chapter 29, paragraph 2 of the Confession states that "those who do actually profess repentance towards God, faith in, and obedience to, our Lord Jesus Christ, are the only proper subjects of this ordinance." The ordinance itself presupposes prior regeneration. One cannot profess repentance and faith unless one has already been born again by the Spirit of God (John 3:3–8; 1 John 5:1). Baptism, in the Baptist economy, is administered to those who give credible evidence of already possessing the very salvation that baptismal regenerationists claim it confers.
The ordinance is thus logically subsequent to regeneration, not causative of it. As Fred Malone argued in The Baptism of Disciples Alone, the proper subjects of baptism are "those disciples of Jesus Christ who have the law written on their heart by the Holy Spirit of God, who know God experientially by faith, and who possess in reality the forgiveness of sins." These alone "are entitled to the new covenant sign of baptism, evidenced by their confession of Christ as Lord."[7]
Sola Fide
Peter grounds the saving efficacy of the believer’s baptismal response not in the water but in the resurrection of Jesus Christ (v. 21b: δι᾽ ἀναστάσεως Ἰησοῦ Χριστοῦ). This is the critical hinge. The resurrection is the Father’s public vindication of the Son’s atoning work — the divine declaration that Christ’s sacrifice was accepted, that the penalty for sin has been paid, and that all who are united to Christ by faith share in His righteousness. Romans 4:25 makes the connection explicit: Christ "was delivered up for our trespasses and raised for our justification." Baptism, as John Gill noted, "is a means of leading the faith of the baptized person, as to the blood of Christ, for pardon and cleansing, so to the resurrection of Christ, to justification." The ordinance of baptism by immersion — being plunged beneath the water and raised again — is itself a figure of both Christ’s death and resurrection and the believer’s death to sin and resurrection to newness of life (Romans 6:3–5).
It pictures justification; it does not produce it.[8]
The ἐπερώτημα — whether rendered "appeal" or "pledge" — links salvation to the conscious exercise of faith, not to a ceremonial act. If it is an appeal, the baptismal candidate is calling upon God for the cleansing of conscience that only Christ’s blood can provide — an act of faith. If it is a pledge, the candidate is making a vow of allegiance to God from a conscience already cleansed by grace — a confession of faith. Either way, the internal disposition of faith is the operative reality; the water is the external occasion.
Peter briefly defines the efficacy and use of baptism, when he calls attention to conscience, and expressly requires that confidence which can sustain the sight of God and can stand before his tribunal… for how can there be a good and pure conscience until our old man is reformed, and we be renewed in the righteousness of God? And how can we answer before God, unless we rely on and are sustained by a gratuitous pardon of our sins?
The Particular Baptists were heirs of this insight. Sam Waldron, in his exposition of the 1689 Confession, noted that whereas in the Old Covenant "covenant status was conferred irrespective of spiritual qualifications," the New Covenant "confers the required response on all those brought into it" — meaning that every member of the New Covenant genuinely knows the Lord, has the law written on the heart, and possesses the forgiveness of sins (Jeremiah 31:31–34). Baptism marks these people out publicly; it does not create them. Samuel Renihan of Founders Ministries summarized the Baptist position well: "Baptism is a two-way declaration. On the one hand, it is God’s visible promise that all who are in His Son are new creations by virtue of their union with Christ in His death and resurrection. And on the other hand, it is the individual’s profession of faith in those very promises."[9]
Definite Atonement
The doctrinal freight of 1 Peter 3:18 is staggering and points unmistakably toward particular redemption. "Christ also suffered once for sins, the righteous for the unrighteous, that he might bring us to God." Every clause in this sentence reinforces definite atonement. The adverb ἅπαξ ("once for all") declares the finality and sufficiency of Christ’s sacrifice — unlike the repeated Levitical offerings, this was a single, completed, effectual act. A sacrifice that must be supplemented by human ritual to become effective is not "once for all"; it is insufficient. The substitutionary preposition ὑπέρ identifies Christ’s suffering as vicarious — the Righteous One in the place of the unrighteous ones. And the purpose clause ἵνα ὑμᾶς προσαγάγῃ τῷ θεῷ ("that he might bring us to God") states the designed outcome of this substitution: not merely to make reconciliation possible for all people indiscriminately, but actually to bring a definite people — "us" — into the presence of God. R.C. Sproul preferred the language of "definite redemption" or "definite atonement" precisely because it communicates that "God the Father designed the work of redemption specifically with a view to providing salvation for the elect, and that Christ died for His sheep and laid down His life for those the Father had given to Him." John Owen’s classic trilemma, frequently deployed by Reformed Baptists, presses the logic: Christ died for either all the sins of all people, some of the sins of all people, or all the sins of some people. If the first, all are saved (universalism). If the second, none are saved. Therefore the third — Christ bore all the sins of His elect people, and
We say Christ so died that he infallibly secured the salvation of a multitude that no man can number, who through Christ’s death not only may be saved, but are saved, must be saved and cannot by any possibility run the hazard of being anything but saved.
The Isaianic background deepens this reading. Peter has already drawn heavily on Isaiah 53 in 1 Peter 2:21–25, quoting directly: "He himself bore our sins in his body on the tree." The singular δίκαιος ("righteous one") of 3:18 echoes the δίκαιον ("righteous one") of Isaiah 53:11 LXX, where the Servant "shall justify many" (δικαιῶσαι δίκαιον εὖ δουλεύοντα πολλοῖς) — the "many" being not all humanity without distinction but those whose iniquities the Servant specifically bore.
Peter’s use of this language is not incidental; it places Christ’s work squarely within the prophetic framework of substitutionary, vicarious, particularized atonement. The one who claims this passage collapses TULIP must explain how a text saturated with the language of Isaiah 53 — the locus classicus of penal substitutionary atonement — somehow undermines the very doctrines that substitutionary atonement entails.[11]
The Five Points via Noah
Peter does not invoke the Noah narrative by accident. His appeal to the flood account in verses 19–20 establishes a typological framework in which every major element of the Genesis narrative finds its antitype in New Covenant salvation — and each element corresponds to one or more of the doctrines of grace.
Total depravity stands as the dark backdrop against which God’s saving mercy shines. The reason only eight souls were saved through the flood is that the entirety of the antediluvian world was sunk in comprehensive, pervasive wickedness. Genesis 6:5 — the foundational proof text for total depravity in Reformed theology — declares that "every intention of the thoughts of his heart was only evil continually." The world that Peter’s readers would have recalled was not a world of basically good people who merely needed moral improvement; it was a world so thoroughly corrupted that only total destruction could answer the demands of divine justice.
The flood is the historical demonstration that apart from sovereign grace, humanity is incapable of righteousness, incapable of seeking God, and deserving only of judgment. Peter’s phrase "when once the longsuffering of God waited in the days of Noah" (v. 20) emphasizes that even the patience of God had a terminus — the depravity of man was so total that only the intervention of grace could rescue anyone at all.[12]
Unconditional election is writ large in Peter’s deliberate emphasis: "few, that is, eight souls were saved" (v. 20). The numerical precision is striking. Out of the entire antediluvian population — conceivably millions — God saved precisely eight. And why was Noah among the eight? Not because of inherent merit or foreseen faith, but because "Noah found grace in the eyes of the LORD" (Genesis 6:8). Grace came first; righteousness followed. Noah was a "preacher of righteousness" (2 Peter 2:5) because he had been made righteous by grace, not the reverse. The pattern of "few" elected out of "many" judged runs through the entirety of Scripture — from the eight in the ark, to Abraham called out of Ur, to the remnant preserved through the exile, to Christ’s own teaching that "narrow is the way which leadeth unto life, and few there be that find it" (Matthew 7:14).
Peter’s invocation of this pattern in the immediate context of a passage about salvation is a deliberate reinforcement of the doctrine of unconditional election. As R. Scott Clark has written at the Heidelblog: "For all who believe, the ark becomes a picture of our salvation by grace alone, through faith alone, in Christ (the ark) alone. It also pictures God’s patience, as it were, in effecting the salvation of his elect."[13]
Definite atonement is typified in the ark itself. The ark was not a generic lifeboat tossed into the waters for whoever might swim to it. It was designed by God with specific dimensions (Genesis 6:14–16), for specific occupants (Genesis 6:18–20), with one door (Genesis 6:16) — and when the time came, God Himself shut that door (Genesis 7:16). The Hebrew word for the pitch (כֹּפֶר, kopher) that sealed the ark and rendered it watertight against judgment is the same root word used throughout the Old Testament for "atonement" — a typological connection too precise to be accidental.
Just as the pitch sealed the ark against the waters of wrath, so Christ’s atoning blood seals His people against the wrath of God. And just as the ark was sufficient for its intended passengers and no others, so Christ’s atonement is effectual for His elect people and actually secures their salvation. The text of 1 Peter 3:18 drives this home: Christ suffered "that he might bring us to God" — not that He might make all humanity potentially saveable, but that He might actually, infallibly bring His people into the Father’s presence.[14]
Irresistible grace is pictured in the sovereign initiative of God throughout the flood narrative. God did not merely announce the availability of the ark and leave it to human decision. He commanded Noah to build it. He brought the animals "two by two unto Noah into the ark" (Genesis 7:9) — they came by divine compulsion, not by their own volition. And in the most striking image of all, "the LORD shut him in" (Genesis 7:16). Noah did not seal himself inside the ark by his own power or wisdom. God shut the door. The salvation of the eight was God’s doing from start to finish — from the design of the ark to the gathering of its occupants to the sealing of its door.
This is a picture of effectual calling: God does not merely offer salvation and hope for a response; He ensures it. He draws His elect irresistibly to Christ, as Christ Himself taught: "No one can come to Me unless the Father who sent Me draws him" (John 6:44). The New Covenant promise of Jeremiah 31:33 — "I will put my law in their inward parts, and write it in their hearts" — is not a conditional offer but a sovereign declaration of what God will do for His people. As Sam Waldron observed, the New Covenant "confers the required response on all those brought into it."[15]
The perseverance of the saints is typified in the absolute security of those inside the ark. Once God shut the door, no flood, no storm, no duration of the waters could dislodge Noah and his family from their place of safety. They did not preserve themselves; the ark preserved them — and behind the ark stood the covenant-keeping God who had placed them there. Peter’s flow of thought confirms this: verse 22 declares that Jesus Christ "has gone into heaven and is at the right hand of God, with angels, authorities, and powers having been subjected to him." The risen, ascended, enthroned Christ — to whom all authority in heaven and earth has been given — is the one who preserves His people through the judgment waters of this present age.
First Peter 1:3–5 states this doctrine in the most explicit terms: believers are "kept by the power of God through faith for salvation ready to be revealed in the last time." The one who entered the ark by God’s sovereign grace will arrive safely on the other side of judgment by that same grace.[16]
Hermeneutics
The objection that reading 1 Peter 3:18–22 through the lens of TULIP amounts to "importing external ideology" onto the text betrays a fundamental misunderstanding of the Reformed hermeneutical method. The principle of the analogia fidei (analogy of faith) and analogia Scripturae (analogy of Scripture) — that Scripture is its own interpreter — is not an imposition from outside the Bible but a principle derived from the Bible’s own self-attesting coherence as the unified Word of a single divine Author. The Second London Baptist Confession of Faith (1689), Chapter 1, paragraph 9, states with crystalline clarity: "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." This principle is not unique to the 1689; it is shared by the Westminster Confession and the Savoy Declaration, and it reflects the universal Protestant commitment to sola Scriptura and the perspicuity of Scripture.
Richard Muller, the preeminent historian of post-Reformation Reformed dogmatics, defines the analogia fidei 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."[17]
When Reformed Baptists read 1 Peter 3:21 in light of Ephesians 2:8–9 ("by grace you have been saved through faith… not of works"), Romans 3:28 ("a man is justified by faith apart from the deeds of the law"), Acts 10:44–48 (Cornelius receiving the Holy Spirit before baptism), and the thief on the cross (Luke 23:43, saved without baptism), they are not importing a foreign system onto the text. They are allowing the clear to interpret the less clear, as the Confession requires. The New Testament teaches with unmistakable clarity that salvation is by grace alone through faith alone in Christ alone. Any interpretation of 1 Peter 3:21 that contradicts this unambiguous teaching must be rejected — not because the doctrines of grace are an "external ideology," but because the Spirit of God does not contradict Himself.
The biblical authors themselves practiced this hermeneutic: the New Testament writers constantly interpret Old Testament texts in light of later revelation (e.g., Revelation 12:9 identifying the serpent of Genesis 3 as Satan; Hebrews 10:1–18 interpreting the Levitical sacrifices in light of Christ’s once-for-all offering). As William Tyndale exhorted: "Mark the plain and manifest places of the Scriptures, and in doubtful places see thou add no interpretation contrary to them; but, as Paul says, let all be conformable and agreeing to the faith."[18]
Verses 19–20
The reference to Christ preaching to "the spirits in prison" (v. 19) has generated centuries of interpretive discussion, but none of the major Reformed interpretations support baptismal regeneration or undermine TULIP. Two readings dominate the Reformed tradition, and both are consistent with the doctrines of grace. The first, championed by Wayne Grudem in his Tyndale commentary on 1 Peter and endorsed by Guy Waters of Reformed Theological Seminary, holds that Christ, by the Holy Spirit, preached through Noah to the antediluvian generation during the 120 years of the ark’s construction. Those who rejected Noah’s preaching are now "spirits in prison" — that is, human souls currently confined in hell.
This reading builds on 1 Peter 1:10–11, where Peter says "the Spirit of Christ" was active in the Old Testament prophets, and on 2 Peter 2:5, which calls Noah "a herald of righteousness" (using vocabulary cognate to κηρύσσω, "to preach," the very verb of 1 Peter 3:19). On this view, the passage illustrates both the patience of God in delaying judgment and the certainty of judgment upon those who reject the gospel — reinforcing total depravity and unconditional election by showing that the majority of humanity rejected the message despite prolonged opportunity, and only the elect remnant was saved.[19]
The second major reading, advocated by Thomas Schreiner in the New American Commentary and by Sam Storms in the TGC commentary, holds that the risen Christ proclaimed His victory to imprisoned fallen angels — specifically the rebellious spirits associated with Genesis 6:1–4 who sinned in the days of Noah. On this view, πνεύματα ("spirits") refers to supernatural beings rather than human souls, and κηρύσσω means "proclaim" (a victory announcement) rather than "preach the gospel." The verb πορευθείς ("having gone") appears both in verse 19 and verse 22, where it clearly refers to Christ’s ascension — suggesting that the "going" of verse 19 is likewise a post-resurrection movement. This reading powerfully reinforces the doctrines of grace: the risen and ascended Christ announces His definitive triumph over all demonic powers, a triumph that verse 22 confirms when it declares that "angels, authorities, and powers" have been subjected to Him. If even the cosmic powers of darkness have been subjugated, how much more secure are the saints whom
It is also likely that what Christ ’proclaimed’ was his definitive triumph over and subjugation of ’angels, authorities, and powers.’
It is also likely that what Christ ’proclaimed’ was his definitive triumph over and subjugation of ’angels, authorities, and powers.’
Neither reading offers any support for a post-mortem second chance at salvation, and neither reading undermines any point of TULIP. Both readings reinforce the sovereignty of God in salvation and the certainty of judgment upon the impenitent.[20]
1689 Covenant Theology
There is a final, uniquely Baptist argument that deserves explicit statement, because it strikes at the root of the baptismal regeneration reading with a force that no paedobaptist tradition can fully replicate. In 1689 Reformed Baptist covenant theology — the system articulated by Nehemiah Coxe in his Discourse of the Covenants (1681), expounded by Pascal Denault in The Distinctiveness of Baptist Covenant Theology, and confessed in the Second London Baptist Confession — the New Covenant consists exclusively of regenerate members. Unlike the Mosaic covenant, which included both believers and unbelievers within its administration, and unlike the Abrahamic covenant of circumcision, which was applied to the physical descendants of Abraham irrespective of their spiritual condition, the New Covenant is established on "better promises" (Hebrews 8:6): "I will put my laws into their mind, and write them in their hearts; and I will be to them a God, and they shall be to me a people: and they shall not teach every man his neighbour, and every man his brother, saying, Know the Lord: for all shall know me, from the least to the greatest" (Hebrews 8:10–11, quoting Jeremiah 31:33–34).
Coxe, the principal editor of the 1689 Confession, argued that "the main hinge of the controversy about the right subjects of baptism turns on Genesis 17," and he demonstrated that Abraham had not "one posterity of a mixed nature (converted and unconverted), but two distinct posterities with their respective promises" — the fleshly and the spiritual. The New Covenant is made with the spiritual seed alone.[21]
This covenantal architecture makes baptismal regeneration not merely unlikely but structurally impossible within the Baptist system. If the New Covenant consists exclusively of the regenerate — those who have been born again, who know the Lord savingly, who have the law written on the heart — then the sign of the New Covenant (baptism) can only rightly be administered to those who already possess covenant membership through regeneration. As Waldron observed, whereas circumcision "demanded a new heart, indeed, but it did not profess a new heart," baptism under the New Covenant is administered exclusively to those who profess — and, by the judgment of charity, credibly evidence — a new heart. The ordinance presupposes the very grace that baptismal regenerationists claim it confers.
To make baptism the instrument of regeneration is to invert the entire covenantal logic: it would mean admitting the unregenerate to the sign of a covenant whose membership is defined by regeneration. This is precisely the error that Denault identified in the paedobaptist system, where "there is no longer any reason to define the terms and the ordinances of the New Covenant based solely on New Testament data" because OT circumcision theology has been imported into NT baptism theology. The Baptist insistence on believer’s baptism is not a mere practice; it is a covenantal conviction with direct soteriological implications.[22]
Conclusion
First Peter 3:18–22, read in its grammatical, historical, and canonical context, does not collapse TULIP. It teaches TULIP. It teaches that the whole world lay under condemnation so total that only eight souls escaped, and those by grace alone. It teaches that those eight were chosen not by merit but by sovereign favour. It teaches that the Righteous One suffered once for the unrighteous — a definite people whom He would infallibly bring to God. It teaches that God shuts the door of salvation from the inside, securing His people against the flood of judgment by His own almighty hand. It teaches that baptism is a sign — an ἀντίτυπον, an antitype, a figure — that pictures the salvation accomplished by Christ’s death and resurrection and applied by the Holy Spirit through the gift of faith. It teaches, in Peter’s own unmistakable words, that this salvation is "not the putting away of the filth of the flesh" but the conscious, faith-filled response of a regenerate heart toward God.
The Particular Baptists of the seventeenth century understood this. Coxe and Keach and Kiffin and Collins confessed it in their Confession. Gill and Fuller expounded it in their commentaries and theologies. Spurgeon thundered it from the pulpit of the Metropolitan Tabernacle. And the text of Holy Scripture, rightly divided, continues to declare it: salvation is of the Lord, from first to last, by grace alone, through faith alone, in Christ alone — and baptism, that blessed ordinance of the New Testament, is the believer’s public, joyful, obedient testimony that this salvation has already been accomplished in the soul by the sovereign work of the triune God.
