A common objection to the older Protestant identification of the Papal system as Antichrist comes from John’s second epistle:
“For many deceivers have gone out into the world who do not confess Jesus Christ as coming in the flesh. This is a deceiver and an antichrist” (2 John 1:7).
The objection sounds simple: John says antichrist denies that Jesus Christ came in the flesh. Rome confesses the Incarnation. Rome teaches that Jesus is true God and true man. Therefore, Rome cannot possibly be Antichrist.
At first glance, that may sound persuasive. But the argument is too narrow. It treats one biblical test of antichristian deception as though it cancels the rest of Scripture’s testimony about Antichrist, the man of sin, the little horn, the beast, and Babylon. It also assumes that “confessing Christ come in the flesh” means nothing more than verbally affirming that Jesus became man.
But John’s warning is deeper than that.
John Is Warning Against False Teachers
John is not merely asking whether someone can repeat the sentence, “Jesus came in the flesh.” He is warning the Church about deceivers, false teachers, and antichristian doctrine. In the same verse, he says that “many deceivers” had gone out into the world. This is not a passing reference to one isolated future figure. John is describing a real and present pattern of religious deception.
That matters because the word “confess” in this context is not a bare verbal formula. To confess Christ is to acknowledge Him truthfully, faithfully, and openly according to who He is. It is to confess the true Christ, not merely use His name. A religious teacher may speak often about Jesus and still corrupt the truth of His person, offices, saving work, mediation, authority, and sufficiency.
This is why Matthew Henry, commenting on 2 John, said the deceiver brings error concerning the person or office of the Lord Jesus and thereby undermines the glory and kingdom of Christ. That is exactly the issue. John is not merely guarding one word about Christ’s body. He is guarding the true confession of the incarnate Son in His full biblical glory.
“The Antichrist” or “An Antichrist”?
Some English translations say “the deceiver and the antichrist,” while others say “a deceiver and an antichrist.” This sometimes confuses readers.
In the Greek text, the definite article is present: “the deceiver and the antichrist.” So, in that sense, “the antichrist” is the more formally literal rendering. But the context begins with “many deceivers.” John is not saying there is only one deceiver in all history. He is identifying the kind of deceiver who belongs to the antichristian pattern.
This fits John’s broader usage. In 1 John 2:18, he says, “even now many antichrists have come.” In 1 John 2:22, he says the one who denies the Father and the Son is antichrist. In 1 John 4:3, he speaks of the spirit of Antichrist already being in the world. So John can speak of Antichrist as something expected, while also speaking of many antichrists and an antichristian spirit already active.
Therefore, 2 John 1:7 cannot be used to force the whole biblical doctrine of Antichrist into one final individual. John’s own language is broader than that. He speaks of a spirit, a pattern, many deceivers, many antichrists, and the antichristian character of false teaching.
Rome’s Formal Confession Should Be Acknowledged
We should be honest about what Rome formally teaches. Rome does not officially say that Jesus was a phantom. Rome does not officially deny that Jesus had a real human nature. Rome does not officially teach that Christ merely appeared to be human. In that narrow verbal sense, Rome affirms what ancient Docetism denied.
That should be acknowledged plainly. A Protestant should not carelessly say, “Rome denies that Jesus became man,” if by that we mean Rome openly rejects the doctrine of the Incarnation. Rome formally confesses that Jesus Christ is true God and true man.
But that does not settle the question.
The issue is whether Rome confesses the incarnate Christ according to His full biblical glory, or whether it claims His name while placing other authorities, priesthoods, mediators, devotions, and traditions where the incarnate Christ alone should stand.
A system may confess Christ with its lips while denying Him in its structure. Scripture itself recognizes this kind of denial. Paul wrote of some who “profess to know God, but in works they deny Him” (Titus 1:16). That principle matters here. Denial is not always verbal. Sometimes denial is practical, structural, and doctrinal, even while orthodox words remain on the surface.
What Does It Mean That Christ Came “in the Flesh”?
To confess that Jesus Christ came “in the flesh” is not merely to say that He had a body. It is to confess that the eternal Son truly entered our human condition in order to redeem us. He did not save from a distance. He took real human nature. He was born of woman (Galatians 4:4). He came from the seed of David according to the flesh (Romans 1:3). He shared in flesh and blood (Hebrews 2:14). He was made like His brethren, yet without sin (Hebrews 2:17; Hebrews 4:15).
This is central to the Gospel. If Christ did not truly come in the flesh, then He did not truly suffer for us, truly die for us, truly rise for us, or truly represent us. His true humanity is necessary for His priesthood, His sacrifice, His mediation, and His saving sympathy with His people.
So John’s test reaches the heart of the Gospel. The question is not merely whether someone says the word “Incarnation.” The question is whether the true incarnate Christ is confessed according to the meaning Scripture gives His incarnation.
The Immaculate Conception and the True Humanity of Christ
This is where Rome’s doctrine of the Immaculate Conception becomes relevant.
Rome teaches that Mary, from the first moment of her conception, was preserved free from all stain of original sin. That doctrine was formally defined in 1854 AD. Rome would say this was done by the grace of God and by virtue of the merits of Christ. So the point should be stated carefully. The issue is not that Rome thinks Mary saved herself, nor that Rome officially denies Christ’s humanity in the same way ancient Docetists did.
The issue is that this doctrine places pressure on the biblical confession that Christ truly came in our flesh.
If Mary had to be uniquely preserved from original sin in order for Christ to take flesh from her, then the system suggests that the Son could not simply assume our real human nature from the ordinary stock of Adam’s race while remaining personally sinless by the power of the Holy Spirit. It introduces a prior sinless human vessel as though Christ’s true humanity required Mary’s immaculate condition.
That is the concern.
The flesh Christ took was not sinful in Him. He was holy, harmless, undefiled, and separate from sinners. But the flesh He took was truly our human nature. He came into the fallen world. He entered the line of Adam, Abraham, and David. He was born of woman. He assumed real humanity, not a specially purified humanity detached from the ordinary condition of the race He came to redeem.
Older Protestant writers saw Rome’s Marian doctrine as a serious corruption of the confession that Christ came in the flesh. Jamieson, Fausset, and Brown made the point bluntly when commenting on 1 John 4:2–3, saying that Rome, by the doctrine of the Immaculate Conception of the Virgin Mary, denies Christ’s proper humanity. The wording is sharp, but the concern is understandable: if Mary must first be exempted from original sin so that Christ can receive flesh from her, then Rome’s doctrine weakens the biblical confession that Christ truly assumed our common humanity, yet without sin.
This does not mean Protestants should say Rome denies the Incarnation in the same simple way as ancient Gnostics or Docetists. The stronger and more accurate argument is this: Rome verbally confesses the Incarnation, yet surrounds it with doctrines that obscure the full force of Christ’s true humanity and sufficiency.
The Problem Is Broader Than One Marian Dogma
The Immaculate Conception is important, but it is not the only issue. The older Protestant case did not rest on one Marian doctrine alone. The deeper issue is that Rome repeatedly places created authorities and mediations where Scripture directs the soul to Christ Himself.
Christ alone is the Head of the Church. Rome places a visible earthly head over the universal Church.
Christ alone is the sufficient High Priest. Rome places an earthly sacrificing priesthood at the center of Christian worship.
Christ offered Himself once for all. Rome places the Mass at the center of the Church as a propitiatory sacrificial offering for the living and the dead.
Christ alone is the one Mediator between God and men. Rome surrounds the soul with priestly mediation, saintly intercession, devotion to Mary, and institutional access points.
Christ rules the conscience by His Word. Rome binds the conscience under church tradition and magisterial authority.
This is why the older Protestant concern was not answered simply by saying, “Rome believes Jesus became man.” The question is whether Rome leaves the incarnate Christ where Scripture places Him.
The Meaning of “Anti”
This is also why the meaning of “anti” matters. Antichristian power is not only power that openly opposes Christ. It can also be power that stands “in the place of” Christ.
The prefix “anti” can carry both senses: against and in the place of. That is important because the Papal system often does not appear first as open atheism or open rejection of Jesus. It appears as religious substitution. It claims to honor Christ while placing a human head, human priesthood, human mediation, human sacrifice, and human tradition in places that belong to Christ alone.
That is exactly what older Protestants meant when they identified the Papal system as antichristian. They did not mean that every Roman Catholic personally opposed Christ or denied every Christian truth. They were identifying a foretold system that rivaled Christ from within the visible Church.
Antichristian deception does not have to say, “Jesus never came in the flesh,” in order to be antichristian. It may say, “Jesus came in the flesh,” while building a system that displaces the offices and sufficiency of the Christ who came.
John’s Test Still Stands
None of this weakens John’s warning. It actually strengthens it.
John’s test is fully true. Every spirit that refuses the true Christ is not of God. Every teacher who denies Jesus Christ coming in the flesh is a deceiver and antichrist. The Church must never soften that warning.
But the true Christ is not confessed merely by correct words about His birth. The true Christ must be confessed in His person, His offices, His saving work, His priesthood, His mediation, His authority, and His sufficiency.
If a system confesses Christ’s name while corrupting His person, obscuring His true humanity, displacing His priesthood, supplementing His mediation, re-presenting His sacrifice, and binding consciences under another authority, then it has not escaped John’s warning simply because it retains orthodox language about the Incarnation.
That is why 2 John 1:7 does not disprove the Protestant identification of the Papal system as Antichrist. It exposes one form of antichristian deception, but it does not exhaust the whole biblical doctrine. Scripture also speaks of the man of sin, the mystery of iniquity, the little horn, the beast, Babylon, false worship, persecution, and religious corruption arising within the visible sphere of God’s people.
John guards the true Christ. Paul, Daniel, and Revelation show how a Christ-rivaling power would unfold in history. These truths belong together.
Conclusion: Rome’s Confession Is Not Enough
Rome formally confesses that Jesus Christ came in the flesh. That should be admitted.
But Rome also surrounds the incarnate Christ with a system that places Mary, priests, saints, sacrifice, tradition, papal headship, and ecclesiastical authority where Scripture directs the sinner to Christ Himself. Rome’s formal confession of the Incarnation does not erase its practical displacement of the incarnate Christ.
The Papal system is not antichristian because it simply says, “Jesus did not come in the flesh.” It is antichristian in the older Protestant sense because it claims to serve the Christ who came in the flesh while standing in places that belong only to Him.
John’s warning remains true. The Christ who came in the flesh must not merely be named. He must be confessed as Scripture reveals Him: the only Head of the Church, the only sufficient High Priest, the only Mediator between God and man, the once-for-all sacrifice for sin, and the only Savior in whom the conscience may rest.
