Did Protestants Think Their Pope Was the One Man of Sin?

As with every study in this series, we should begin with the right spirit, marked by love for one another. The purpose here is not hostility toward individual Catholics, nor even a reckless judgment of every individual pope as though we could see every man’s soul. The purpose is to now answer a common strawman argument against the Traditional Protestant Interpretation: the claim that the Reformers foolishly thought their particular pope was the one final man of sin, and that when that pope died, their interpretation was disproven.

That argument badly misrepresents the older Protestant claim.

The Reformers and the Protestant confessions did not need to identify each individual pope as a separate, final, end-time man of sin. They identified the papal office and system as the man of sin, Antichrist, and the self-exalting power within the visible Church. Individual popes come and go, but the office continues. The point was not one isolated man in one generation, but a continuing succession, office, and system — a rival headship inside the professing Church.

The Strawman Argument

The argument often sounds something like this:

“The Reformers thought their pope was the man of sin. But that pope died, and Jesus did not return to destroy him. Therefore, the Reformers were wrong.”

At first, that may sound convincing to someone who has only been taught a Futurist framework. If the man of sin must be one final individual who appears shortly before Christ returns, then any pope who dies before the Second Coming obviously cannot be that one man.

But that simply assumes the Futurist conclusion before the argument begins.

The Historicist claim was different. Older Protestants did not say, “This one pope, as an isolated individual, must personally remain alive until Christ returns.” They said that the papal office, embodied through a succession of popes, was the self-exalting man of sin system Paul had warned about. The individual men die. The office remains. The claims continue. The system persists.

That distinction matters.

If a king dies, the kingdom may remain. If a bishop dies, the bishopric may remain. If a president dies or leaves office, the presidency remains. In the same way, if a pope dies, the papal system is not thereby destroyed. The prophetic question is not whether an individual man lives for centuries. The question is whether Scripture can speak of a continuing office, kingdom, or system under singular language.

And Scripture does this often.

Scripture Can Use Singular “Man” Language Representatively

The objection assumes that because Paul says “man of sin,” he must mean one isolated individual living in one final generation. But Scripture itself often uses singular man-language in a representative or corporate way.

Adam is one man, yet in Romans 5 he represents the whole fallen race in him. Christ is one Man, yet He represents the new humanity redeemed in Him. Paul can also speak of the “old man” and the “new man,” not merely as one individual person, but as a larger identity shared by those who belong either to the old creation or the new creation. In Ephesians 2:15, Paul says Christ created Jew and Gentile into “one new man,” clearly referring to a corporate people united in Christ, not one biological individual.

That matters when we come to 2 Thessalonians 2. The phrase “man of sin” does not automatically require one short-lived individual. Scripture already gives us categories for representative man-language, corporate identity, and continuing powers embodied through many persons. Paul’s “man of sin” can therefore describe a lawless, self-exalting office and system embodied in a succession of men.

This also fits the wider prophetic background. Daniel had already shown a continuing self-exalting power under the symbol of the little horn, speaking great words, wearing out the saints, and continuing for “a time and times and half a time.” Revelation gives the same period as 42 months and 1260 days. Historicists understood that period prophetically as 1260 years. A single ordinary man could not fulfill that. A continuing office or system could.

So when Paul speaks of the “man of sin,” older Protestants did not isolate that phrase from Daniel and Revelation. They read Paul in harmony with the broader prophetic pattern. Daniel had shown a continuing self-exalting power. Revelation had shown a beastly Roman system enduring through symbolic prophetic time. Paul then described the same broad reality from another angle: a lawless, self-exalting power sitting in the temple of God.

That is why the Protestant interpretation focused on the papal office. The pope was not viewed merely as one particularly sinful man among many. The papal office was seen as the visible headship of a system that exalted itself within the professing Church, claimed authority over doctrine and conscience, placed mediators and sacramental structures where Christ alone should stand, and wore out the saints across history.

The Papal Office, Not Merely One Pope

This is why confessional Protestants spoke the way they did. They did not merely say that one particular pope was personally the whole fulfillment. They spoke of the Pope of Rome in an official and institutional sense.

The original Westminster Confession of Faith said there is no other head of the Church but the Lord Jesus Christ, and that the pope of Rome cannot in any sense be head of it, “but is that Antichrist, that man of sin, and son of perdition.” The Savoy Declaration and the Second London Baptist Confession carried forward the same basic judgment.

That language was not aimed merely at one passing individual. It was aimed at an office claiming headship where Christ alone is Head.

That is why the death of an individual pope does not refute the older Protestant position. The claim was never that one man in one generation would personally exhaust the entire prophecy. The claim was that the papal system, continuing through successive popes, was the prophesied rival headship inside the visible Church.

The system remains even when its officeholders change.

“But Christ Destroys the Man of Sin at His Coming”

A critic may respond, “But 2 Thessalonians 2 says the Lord will consume the lawless one with the breath of His mouth and destroy him with the brightness of His coming. If the pope died before Christ returned, then he could not have been the man of sin.”

But again, that objection only works if the man of sin must be one isolated individual.

If the man of sin is a continuing office and system, then Paul’s statement makes perfect sense. The system continues until Christ finally destroys it. Individual representatives of that system may die across the centuries, but the office, claims, and antichrist principle remain until the Lord brings the whole apostate structure to its end.

This also harmonizes with John’s language. John says that “the spirit of the Antichrist” was already in the world. That does not require one man to be alive through all the centuries of church history. It shows that Antichrist can be understood not merely as one passing individual, but as a spirit, principle, and system of opposition to Christ — especially when that opposition takes the form of substitution in Christ’s place.

This is not strange. Scripture can speak of a kingdom, office, or corporate power as though it were one figure. Daniel’s fourth beast continues beyond individual rulers. The little horn continues beyond one man. Babylon can be spoken of as a woman, a city, and a system. The beast can be described as a single entity while having heads, horns, kings, and phases. Biblical prophecy often personifies systems.

So when Paul says the Lord will destroy the man of sin at His coming, Historicists understood that as the final destruction of the lawless papal system animated by the Antichrist principle, not the biological death of one pope who happened to live during the Reformation.

Why the Succession Matters

The papacy is especially suited to this kind of prophetic identification because it is a continuing office embodied in successive men. Each pope inherits the claims of the office. Each pope sits in the same ecclesiastical seat. Each pope stands within the same Roman system. Each pope receives the titles, authority, and expectations of the papal structure.

That is why older Protestants could look beyond one man. They were not merely reacting to the moral failures of a particular pope. They were looking at a continuing system of authority that claimed to stand over the whole visible Church.

The issue was not merely that some popes were corrupt. The issue was that the papal office itself claimed a place Scripture never gave it.

Christ alone is the Head of the Church. Christ alone is the one Mediator between God and men. Christ alone is the great High Priest. Christ alone gives direct access to the Father. Christ alone rules the conscience by His Word and Spirit.

But Rome placed a visible human head over the Church. It built a sacramental priesthood that claims to act in the person of Christ. It bound consciences through confession, penance, indulgences, purgatory, and ecclesiastical law. It claimed authority to define doctrine and govern the faith of the world. Older Protestants saw in that system the very pattern Scripture had warned about: not merely opposition to Christ from outside the Church, but substitution in Christ’s place within the visible Church.

The Protestant Claim Still Stands

The strawman argument makes the Reformers look foolish for a claim they were not actually making. It portrays them as though they pointed to one pope as the man of sin, yet were disproven when that pope died. But that was not the Historicist case. The Historicist case was broader, deeper, and more biblical. It saw Daniel, Paul, and John describing a continuing apostate power arising within the Roman world and inside the visible Church.

The death of one pope no more disproves Historicism than the death of one Roman emperor disproves Daniel’s fourth beast. Prophecy can identify a kingdom, office, or system that continues through many individual rulers. That is exactly how Daniel’s symbols work, and it is also how the papal system has functioned.

Older Protestants were not saying that each pope was a separate final Antichrist whose death disproved the prophecy. They were saying that the papal office itself was the continuing Antichrist system — the man of sin embodied through succession, the little horn in ecclesiastical form, and the rival headship inside the visible Church.

So the real question is not whether a particular pope died before Christ returned to destroy the lawless one. The real question is whether the papal office and Roman system have continued to preserve the marks Scripture warned about: self-exaltation within the temple of God, rival headship, substitute mediation, authority over conscience, persecution of the saints, and long historical continuity inside the professing Church.

Once the claim is stated correctly, the objection loses its force. The Reformers were not waiting for one pope to live forever until Christ returned. They were warning that a continuing papal system had arisen where Christ alone should stand. That warning has not been disproven. It has been forgotten, caricatured, and dismissed by people who often never understood it in the first place.
