The Comma Johanneum
A late Trinitarian gloss—and the abundant apostolic ground beneath the Trinity
On this page
The King James Version contains a Trinitarian expansion at 1 John 5:7–8:
“For there are three that bear record in heaven, the Father, the Word, and the Holy Ghost: and these three are one. And there are three that bear witness in earth, the Spirit, and the water, and the blood: and these three agree in one.”
The bold portion is traditionally called the Comma Johanneum. Comma here means a short clause; Johanneum means “Johannine” or “of John.”
The textual decision is the clearest of the three famous cases in Sessions 6–8. The Comma did not belong to 1 John. It developed in Latin interpretation and transmission, entered a few late Greek manuscripts, and reached the printed Greek text used by the King James translators.
That conclusion is not a verdict against the Trinity. The church confessed the Triune God long before the Comma appeared in Greek, and it did so from apostolic texts whose wording is not in question.
1. Read the two forms side by side
| KJV | A representative modern form |
|---|---|
| Three bear record in heaven: Father, Word, Holy Ghost; three bear witness on earth: Spirit, water, blood | Three testify: the Spirit, the water, and the blood |
The NKJV retains the longer wording in its text and footnotes that the relevant critical and majority Greek traditions omit it. Many modern translations do not bracket the Comma because it is not part of the Greek text they are translating; a footnote may identify the later reading.
The question is not whether the added words express a Christian idea. The question is whether John wrote them.
2. External evidence: absent from the early Greek tradition
None of the great early Greek biblical codices contains the Comma. It is absent from Sinaiticus, Vaticanus, Alexandrinus, and Ephraemi. It is also absent from the Greek manuscript tradition for many centuries.
The handful of Greek witnesses that contain it are late. Some place it only in the margin, written by a later hand. Codex Montfortianus—manuscript 61—was made in England around the early sixteenth century and is now at Trinity College Dublin. It is named for a later owner, Thomas Montfort, a Cambridge scholar; it was not named for “Lord Montfort.” Its wording bears the marks of translation from Latin into Greek.
The Comma is likewise absent from the early Syriac, Coptic, Armenian, Georgian, and Ethiopic traditions. The Old Syriac witnesses often mentioned in New Testament textual discussion contain only the Gospels, so they cannot testify directly about 1 John. The Peshitta’s form of 1 John does not contain the Comma.
The positive evidence begins in Latin interpretation and Latin manuscripts, not in early Greek copies of 1 John.
3. The Greek fathers did not use it
The fourth century brought sustained controversy over the relation of the Father, Son, and Holy Spirit. Greek theologians assembled and debated the texts that bore on the doctrine. A line naming the Father, the Word, and the Spirit and declaring the three one would have been extraordinarily useful.
Yet Athanasius, Basil of Caesarea, Gregory of Nazianzus, Gregory of Nyssa, and other Greek writers do not appeal to the Comma. Their silence is powerful because the setting gave them every reason to cite it if it stood in their copies.
This is an argument from silence with a well-defined expectation: writers exhaustively engaged in Trinitarian exegesis do cite many other passages, but not this one.
4. How a Latin interpretation became text
The history can be traced in stages.
An interpretation of the three witnesses
First John names the Spirit, the water, and the blood as three witnesses. Latin Christians read those three in a Trinitarian way. Cyprian, around the middle of the third century, writes of the Father, Son, and Holy Spirit and uses the phrase “these three are one.” Defenders of the Comma have treated this as a direct quotation. It is more naturally understood as a theological interpretation of the three witnesses in the verse already known.
A clear Latin form
Priscillian, a fourth-century Spanish bishop, supplies the earliest clear citation of the Comma’s wording. Over time, the Trinitarian interpretation appears as a gloss—an explanatory note—in Latin transmission. It then moves into the body of some Latin biblical manuscripts and eventually becomes common in later forms of the Vulgate.
A late return to Greek
The wording later crosses from Latin into a small number of Greek manuscripts, many of them close to or later than the rise of the printed Greek New Testament. This direction of travel explains why the Greek can sound like a rendering of Latin rather than Johannine composition.
The history is not “modern scholars removed a Trinitarian verse.” It is “a Trinitarian interpretation grew in the Latin tradition and was later copied into a few Greek witnesses.”
5. Internal evidence: John’s witnesses are on earth
Read 1 John 5:6–9 without the Comma. The argument moves tightly:
- Jesus Christ came by water and blood.
- The Spirit testifies because the Spirit is truth.
- The Spirit, the water, and the blood supply three agreeing witnesses.
- Human testimony is received; God’s testimony concerning his Son is greater.
The “water and blood” have been interpreted in several ways, commonly with reference to Jesus’s baptism and death. Whatever decision is made there, the paragraph concerns God’s historical testimony to the Son.
Insert the Comma, and John briefly introduces a second heavenly triad before returning to the earthly witnesses. The added statement is theologically resonant but interrupts the line of testimony. It behaves like an explanatory comment prompted by the three witnesses.
No common copying accident explains how an original Comma disappeared from every early Greek witness and from the Greek patristic debate. The reverse history is easy to picture: a reader gives the three witnesses a Trinitarian interpretation, the note enters Latin copies, and a much later scribe brings it into Greek.
6. Ask the master question
| If John wrote the Comma | If John did not write the Comma |
|---|---|
| It must vanish from the Greek tradition for many centuries | A Trinitarian interpretation of verse 8 develops in Latin Christianity |
| Early non-Latin translations must all omit it | The interpretation is written as a gloss and enters Latin biblical text |
| Greek theologians must overlook their clearest possible proof text in the fourth-century debates | Late Greek copies receive wording translated back from Latin |
| The wording must later reappear chiefly in very late text or marginal notes | The printed Textus Receptus inherits the wording from that late stage |
Only the second history accounts for every stage without special pleading. The Comma is a later interpolation, and even modern editions that give the Byzantine or Majority Text substantial weight omit it.
7. How it entered the Textus Receptus
The story of Erasmus needs to be told without turning him into either a villain or a hero who single-handedly resisted corruption.
| Date | Development |
|---|---|
| 1516 and 1519 | Erasmus prints his first two Greek New Testaments without the Comma because his Greek manuscripts do not contain it |
| Early 1520s | Critics, including Diego López de Zúñiga (Stunica), press him over the omission |
| Around 1520 | Codex Montfortianus is produced in England with the Comma in Greek translated from the Latin tradition |
| 1522 | Erasmus includes the Comma in his third edition while recording doubts in his annotations |
| Later sixteenth and seventeenth centuries | Stephanus, Beza, and the Elzevir tradition carry it into the printed text later called the Textus Receptus |
| 1611 | The King James translators render the Greek text available to them, Comma included |
Popular retellings sometimes say Erasmus made a formal promise to insert the passage if a single Greek manuscript could be produced and that a manuscript was fabricated specifically to force his hand. The surviving evidence does not justify telling every part of that story with certainty. The safer outline is enough: Erasmus lacked Greek support, controversy grew, a recently made Greek witness appeared, and he included the reading against his better judgment.
Codex Montfortianus is now in Dublin, not Cambridge. Its name comes from Thomas Montfort, not from its place of manufacture or a noble title.
8. Luther did not need the Comma
Luther’s German New Testament did not include the Comma during his lifetime, including revisions after Erasmus’s 1522 edition. Later editors added it to some printings of Luther’s Bible after his death.
That fact does not settle the manuscript question by authority, but it is pastorally clarifying. Lutheran confession of the Trinity never depended on these words. Chemnitz belongs to the sixteenth century, and later Lutheran theologians must each be read in their own context; broad claims that particular orthodox writers uniformly rejected or defended the Comma should not be made without checking their actual works.
The Augsburg Confession confesses one divine essence and three persons without needing the passage. The ecumenical creeds likewise stand on the broad apostolic witness.
9. The Trinity stands on abundant text
Removing a late gloss from 1 John does not remove the Father, Son, and Holy Spirit from Scripture.
The three named together
- Matthew 28:19: Baptism is commanded in the one name of the Father, the Son, and the Holy Spirit.
- 2 Corinthians 13:14: Paul blesses the church with the grace of Christ, the love of God, and the fellowship of the Holy Spirit. Verse numbering differs in some traditions.
- 1 Corinthians 12:4–6: The same Spirit, Lord, and God work in the church’s gifts.
The Son confessed as divine
- John 1:1–18
- Philippians 2:5–11
- Colossians 1:15–20
- Hebrews 1:1–3
The Spirit confessed as divine
- Acts 5:3–4: Peter describes Ananias’s lie as a lie to the Holy Spirit and to God.
- 1 Corinthians 2:10–11: The Spirit knows the depths of God as a person’s own spirit knows that person.
The three acting in salvation
- Galatians 4:4–6
- Ephesians 1:3–14
- Titus 3:4–6
- 1 Peter 1:1–2
The Father sends, the Son redeems, and the Spirit gives life and dwells in the baptized. The doctrine of the Trinity is the church’s account of this whole scriptural witness, not a theory suspended from one proof text.
10. The three famous cases compared
| Mark 16:9–20 | John 7:53–8:11 | 1 John 5:7–8 | |
|---|---|---|---|
| Signature in the evidence | Several different endings | Several different locations | Absent from early Greek; appears in late Greek after developing in Latin |
| Pastoral weight | Resurrection, commission, Baptism, ascension | A beloved portrait of mercy | Explicit Trinitarian language |
| Secure ground elsewhere | Matthew 28; Luke 24; Acts 1; 1 Peter 3:21 | Luke 7 and 15; John 4; Matthew 7 | Matthew 28:19; 2 Corinthians 13:14; many more |
| Historical judgment | An ancient longer ending, probably not written by Mark | An early story, probably not written by John | A later Latin gloss, not written by John |
The ability to identify these additions should increase confidence in the manuscript tradition. The evidence did not conceal them. Their age, movement, distribution, and wording leave recoverable trails.
Preservation does not mean that every copyist or printed editor made no mistake. It means the church received a rich and public stream of witnesses in which changes can be examined rather than guessed at.
Practice
Open 1 John 5:7–8 in Ad Fontes NT.
- Which displayed editions include the longer wording?
- Read 1 John 5:6–9 without it. Write John’s argument as four short steps.
- Insert the Comma. Where does the argument pause or change direction?
- Build a Trinity reference list using only the undisputed passages in section 9.
- Write a two-sentence response to “Modern Bibles removed the verse about the Trinity.”
Discussion
- Why does the silence of fourth-century Greek theologians carry unusual weight in this case?
- How can a theologically true comment still be textually secondary?
- What does Erasmus’s decision teach about scholarly work under ecclesiastical pressure?
- Why is it healthier for doctrine to rest on the whole witness of Scripture than on one unusually explicit verse?
- Which of the three famous cases has been hardest for you, and why?

Before the next session
Read: Chapter 8, “Christological Reinforcement.”
Do one thing: Compare John 1:18 and 1 Timothy 3:16 in a KJV and a modern translation. Record the wording and the footnotes without deciding in advance which reading sounds “stronger.”
Bring: Your Bible, your notes on those two verses, and your vocabulary pages.
Think about: Where did you learn to confess the Trinity—from one proof text, from the creeds and liturgy, from Baptism, or from Scripture’s whole pattern?
A closing word
Thanks be to God for a manuscript record strong enough to show us both what John wrote and what later devotion added. Thanks be to God that no late gloss is needed for the church to confess the Father, the Son, and the Holy Spirit. And thanks be to God for the one name spoken over the baptized, the name in which the church prays and lives.
“The grace of the Lord Jesus Christ and the love of God and the fellowship of the Holy Spirit be with you all.”
