1 John 4:2
By this is the spirit of God known. Every spirit which confesseth that Jesus Christ is come in the flesh, is of God:
The verse in its languages
- Vulgate (Clementine)
- In hoc cognoscitur Spiritus Dei : omnis spiritus qui confitetur Jesum Christum in carne venisse, ex Deo est :
- Greek New Testament (SBLGNT)
- ἐν τούτῳ γινώσκετε τὸ πνεῦμα τοῦ θεοῦ· πᾶν πνεῦμα ὃ ὁμολογεῖ Ἰησοῦν Χριστὸν ἐν σαρκὶ ἐληλυθότα ἐκ τοῦ θεοῦ ἐστιν,
Haydock's commentary
By this is the Spirit of God known. He gives the new converts first this general mark, by which they might have good grounds to think that the teachers they met with in those days had a good spirit, were of God, if they confessed and acknowledged Jesus Christ to have come from heaven and to have been made flesh, or made man; i.e. to be truly God and truly man. But if (ver. 3) they met with teachers of such a spirit as dissolveth Jesus,1 by denying him either to be the Messias or to be truly God, or to be a true man, they might conclude for certain that such men had not a true spirit, but were heretics, antichrists, and forerunners of the great antichrist. Such, even in St. John's time, was Simon the magician, who, according to St. Epiphanius, (hær. xxi. p. 55. Ed Petav.) pretended among his countrymen, the Samaritans, that he himself was God the Father, and among the Jews that he was God the Son, and that Jesus suffered death in appearance only. His disciple also, Menander, said he was sent from heaven for the salvation of men. See St. Epiphanius, hær. xxii. p. 61. 3. Cerinthus, as also Carpocras, held that Jesus was a mere man, born of Joseph and Mary, and also different from Christ. See St. Epiphanius, hær. xxxvii. and xxix. p. 102. and 110. 4. Ebion held much the same. See the same St. Epiphanius, hær. xxx. p. 142. These heretics and divers of their followers divided Jesus, and destroyed the faith and mystery of the incarnation. (Witham)
Every spirit which confesseth, &c. Not that the confession of this point of faith alone, is at all times and in all cases sufficient; but that with relation to that time, and for that part of the Christian doctrine, which was then particularly to be confessed, taught, and maintained against the heretics of those days, this was the most proper token by which the true teachers might be distinguished from the false. (Challoner)
1 Qui solvit Jesum. Kataluei is read in some manuscripts and must have been the reading which the Latin interpreter followed. We read the same in St. Irenæus, lib. 3. chap. xviii. p. 197. Ed. Feuardentii; in Tertullian, lib. 5. contra Marcion. chap. xvi. p. 481. Ed. Rigaltii; in St. Augustine in his commentary on these words, trac. 6, p. 871.
Haydock wrote amid the controversies of his day. The Church teaches that those born into communities separated from her cannot be charged with the sin of separation, and embraces them as brothers (CCC 818).

The Fathers on this verse
Tertullian The Five Books Against Marcion, The Second Epistle to the Thessalonians. An Absurd Erasure of Marcion; Its Object Transparent. The Final Judgment on the Heathen as Well as the Jews Could Not Be Administered by Marcion's Christ. The Man of Sin--What? Inconsistency of Marcion's View. The Antichrist. The Great Events of the Last Apostasy Within the Providence and Intention of the Creator, Whose are All Things from the Beginning. Similarity of the Pauline Precepts with Those of the Creator
We are obliged from time to time to recur to certain topics in order to affirm truths which are connected with them. We repeat then here, that as the Lord is by the apostle proclaimed as the awarder of both weal and woe, He must be either the Creator, or (as Marcion would be loth to admit) One like the Creator, “with whom it is a righteous thing to recompense tribulation to them who afflict us, and to ourselves, who are afflicted, rest, when the Lord Jesus shall be revealed as coming from heaven with the angels of His might and in flaming fire.” The heretic, however, has erased the flaming fire , no doubt that he might extinguish all traces herein of our own God. But the folly of the obliteration is clearly seen. …
Tertullian Against Praxeas, Christ Not the Father, as Praxeas Said. The Inconsistency of This Opinion, No Less Than Its Absurdity, Exposed. The True Doctrine of Jesus Christ According to St. Paul, Who Agrees with Other Sacred Writers
And so, most foolish heretic, you make Christ to be the Father, without once considering the actual force of this name, if indeed Christ is a name, and not rather a surname, or designation; for it signifies “Anointed.” But Anointed is no more a proper name than Clothed or Shod; it is only an accessory to a name. Suppose now that by some means Jesus were also called Vestitus ( Clothed ), as He is actually called Christ from the mystery of His anointing, would you in like manner say that Jesus was the Son of God, and at the same time suppose that Vestitus was the Father? Now then, concerning Christ, if Christ is the Father, the Father is an Anointed One, and receives the unction of course from another. Else if it is from Himself that He re ceives it, then you must prove it to us. …
St Cyprian Three Books of Testimonies Against the Jews, That although from the beginning He had been the Son of God, yet He had to be begotten again according to the flesh
In the second Psalm: “The Lord said unto me, Thou art my Son; this day have I begotten Thee. Ask of me, and I will give Thee the nations for Thine inheritance, and the bounds of the earth for Thy possession.” Also in the Gospel according to Luke: “And it came to pass, when Elisabeth heard the salutation of Mary, the babe leaped in her womb; and she was filled with the Holy Ghost, and she cried out with a loud voice, and said, Blessed art thou among women, and blessed is the fruit of thy womb. And whence does this happen to me, that the mother of my Lord should come to me?” Also Paul to the Galatians: “But when the fulness of the time was come, God sent His Son, born of a woman.” Also in the Epistle of John: “Every spirit which confesses that Jesus Christ is come in the flesh is of God. But whosoever denies that He is come in the flesh is not of God, but is of the spirit of Antichrist.”
St Augustine Ten Homilies on the First Epistle of John, 1 John III. 19, IV. 3
12. There remains then the test by which it is to be proved to be the Spirit of God. He has indeed set down a sign, and this, belike, difficult: let us see, however. We are to recur to that charity; it is that which teacheth us, because it is the unction. However, what saith he here? “Prove the spirits, whether they be from God: because many false prophets have gone out into this world.” Now there are all heretics and all schismatics. How then am I to prove the spirit? He goes on: “In this is known the Spirit of God.” Wake up the ears of your heart. We were at a loss; we were saying, Who knows? who discerns? Behold, he is about to tell the sign. …
St Augustine Ten Homilies on the First Epistle of John, 1 John V. 1-3
3. “In this we know that we love the sons of God.” What is this, brethren? Just now he was speaking of the Son of God, not of sons of God: lo, here one Christ was set before us to contemplate, and we were told, “Whosoever believeth that Jesus is the Christ is born of God: and every one that loveth Him that begat,” i.e. the Father, “loveth Him also that is begotten of Him,” i.e. the Son, our Lord Jesus Christ. And he goes on: “In this we know that we love the sons of God;” as if he had been about to say, “In this we know that we love the Son of God.” He has said, “the sons of God,” whereas he was speaking just before of the Son of God, because the sons of God are the Body of the Only Son of God, and when He is the Head, we the members, it is one Son of God. …
Theodoret Dialogues. The “Eranistes” or “Polymorphus” of the Blessed Theodoretus, Bishop of Cyrus, The Immutable
Orth. What was taken of him was not man’s likeness, but man’s nature. For “form of a servant” is understood just as “the form of God” is understood to mean God’s nature. He took this, and so was made in the likeness of man, and was found in fashion as a man. For, being God, He seemed to be man, on account of the nature which He took. The evangelist, however, speaks of His being made in the likeness of man as His being made flesh. But that you may know that they who deny the flesh of the Saviour are of the opposite spirit, hear the great John in his Catholic Epistle saying “Every spirit that confesses that Jesus Christ is come in the flesh is of God, and every spirit that confesses not that Jesus Christ is come in the flesh is not of God, and this is that spirit of Anti-Christ.”
St Ambrose Exposition of the Christian Faith, Chapter II. Since it has been proved that the Son is true God, and in that is not inferior to the Father, it is shown that by the word solus (alone) when used of the Father in the Scriptures, the Son is not excluded; nay, that this expression befits Him above all, and Him alone. The Trinity is alone, not amongst all, but above all. The Son alone does what the Father does, and alone has immortality. But we must not for this reason separate Him from the Father in our controversies. We may, however, understand that passage of the Incarnation. Lastly the Father is shut out from a share in the redemption of men by those who would have the Son to be separated from Him
36. Wherefore let them understand that in this passage the Son is not to be separated from the Father, Who is the only true God. For they cannot prove that the Son is not the only and true God, especially as here also it may be gathered, as I have said, that Christ too is true and only God; or the passage may at least be understood partly in reference to the Godhead of the Father and the Son, and partly to the Incarnation of Christ: for knowledge is not perfect unless it confesses Jesus Christ from eternity to be only-begotten God, true Son of God, and, according to the flesh, begotten of a Virgin. Which also this very Evangelist has taught us elsewhere, saying: “Every spirit that confesseth that Jesus Christ is come in the flesh, is of God.”
