Open a King James Bible at 1 John 5:7. You’ll find the clearest statement of the Trinity in the whole Bible. Three Persons. One God. One sentence. Nothing else in Scripture says it so plainly.

Now open an ESV, an NIV or a NASB. The sentence has been edited out.

So somebody is wrong, and badly wrong. Either modern translators have cut a verse out of the Word of God, or human hands added those words long ago and nobody removed them for a 1000 years. There’s no gentle middle option here.

This post walks you through the evidence in plain language.

First, what is the “Johannine Comma”?

The name sounds technical. It’s not.

• “Johannine” simply means “belonging to John”. It refers to John, the apostle who wrote this letter.
• “Comma” here has nothing to do with punctuation. It comes from the Greek word komma, which means a short piece of a sentence—a clause.

So “the Johannine Comma” just means “the short clause in John’s letter”. Scholars also call it the Comma Johanneum. Both names mean the same thing.

Here’s what’s actually in dispute.

The disputed words are the ones about the three witnesses in heaven. Everything else in the passage is agreed by everybody. The argument is about roughly 24 Greek words.

3 simple facts before we start

To weigh the evidence we need 3 facts about how the Bible has reached us.

• We don’t have the originals. The sheets John wrote on decayed long ago. What God gave us instead is an enormous number of hand-written copies. This is how He has preserved His Word.
• John wrote in Greek. So Greek copies are the primary witnesses. Latin copies are translations, one step further from the author.
• The early pastors quoted the Bible constantly. If a verse was in their Bibles, they quoted it—especially when it helped them win an argument. Keep this third point in mind. It’s the hinge of the whole case.

Evidence 1: 13 centuries of Greek silence

About 500 hand-written Greek copies of 1 John have survived. Roughly 9 of them contain the Comma.

9 out of 500 is striking enough. The detail is far worse than the number.

• No Greek copy before the 1300s has the words in the text. Not 1. The 2 great complete Bibles from the 300s, Codex Sinaiticus and Codex Vaticanus, don’t have them. Neither does Codex Alexandrinus. Neither does any papyrus.
• 4 of the 9 don’t really count. In the manuscripts numbered 88, 221, 429 and 636, the words aren’t in the text at all. Somebody has written them in the margin, in handwriting from the 1500s. That’s a reader’s note added later, not Scripture copied from an older book.
• The earliest Greek copy with the words in the text is manuscript 629, from the 1300s. It’s a 2-language book, Latin down 1 column and Greek down the other, and its Greek has been quietly adjusted to match the Latin.
• 1 of the others, Codex Montfortianus, was written around 1520. That’s after the printing press and after Columbus crossed the Atlantic. We’ll meet it again shortly.

Now widen the search. Within a few centuries the New Testament was translated for the churches of Syria, Egypt, Armenia, Georgia and Ethiopia. Each translation is an independent witness to what the Greek said at the time.

Read down the right-hand column. The word “yes” appears only in Latin, and only late. That single pattern is the shape of the whole problem.

Evidence 2: The silence that shouts

This is the argument that settles the matter, and it’s one most readers have never heard.

In about AD 318, a preacher in Egypt named Arius began teaching that the Son of God was a created being—the highest of all creatures, but still a creature, and not God in the full sense. The church was thrown into a century of conflict. Councils met at Nicaea in 325 and at Constantinople in 381. Pastors were exiled. Emperors changed sides. It was the fiercest doctrinal war the church has ever fought.

The men who defended the deity of Christ wrote in Greek: Athanasius of Alexandria, Basil of Caesarea, Gregory of Nazianzus, Gregory of Nyssa, Cyril of Alexandria, John Chrysostom. They ransacked the Scriptures for every verse that would serve, arguing over single word and single letter.

Not 1 of them ever quotes the Johannine Comma. Not once, in a 100 years of writing. The councils never quote it. The creeds never quote it. Greek writers even quote 1 John 5:8—the very next line—and stop precisely where the Comma would begin.

Silence is often weak evidence. This isn’t ordinary silence. It’s silence from the men who needed the verse most, at the moment they needed it, in the language it was supposedly written in.

Evidence 3: We can watch the words being born

If the Comma was added, an obvious question follows: added by whom? And how? Here the trail is unusually clear, and it leads to the Latin-speaking churches of North Africa and Spain.

Latin preachers loved to find hidden pictures in the text. In 1 John 5:8 the apostle says three things testify: the Spirit, the water and the blood. So they said: three witnesses, and they’re one—there is a picture of the Trinity.

How the clause entered the Bible: a timeline

• About AD 200-250—Tertullian and Cyprian. Both read verse 8 as a symbol of the Trinity. Cyprian writes it’s written of the Father, Son and Holy Spirit, “and these 3 are one”. This is the strongest card the other side holds. But he’s not quoting the heavenly witnesses. He’s quoting the symbolic reading of the earthly ones.
• About AD 380—Priscillian. The first person to quote the words clearly as Scripture. He was a Spanish bishop later executed for heresy, and his wording sits in a different order from ours.
• About AD 400—Augustine. The decisive moment. Augustine writes a long book against an Arian bishop named Maximinus. He needs Trinity texts desperately. He turns to 1 John 5, and argues from the symbolic reading of spirit, water and blood. Had the Comma been in his Bible he had every reason to quote it. He didn’t, because it wasn’t there.
• AD 484—Carthage. African bishops, under pressure from Arian rulers, place the words in a written confession of faith. From here they begin to look official.
• AD 546 and about AD 700—Fuldensis and Amiatinus. The 2 finest early copies of Jerome’s Latin Vulgate still lack the Comma. Fuldensis is remarkable: it carries a preface accusing careless translators of dropping the heavenly witnesses, then prints the passage without them.
• AD 800-1200—the words settle in. Latin copies increasingly include them, until by the 13th century every Latin Bible in Europe has them and nobody recalls a time when they were absent.

Evidence 4: Erasmus, and a story you’ve probably been told wrongly

In 1516, Dutch scholar Desiderius Erasmus published the first printed Greek New Testament. He left the Comma out, for the simple reason none of his Greek manuscripts contained it.

The storm was immediate. He was accused of reviving the heresy of Arius. In his third edition of 1522 he printed the words, after being shown the Codex Montfortianus mentioned above. Erasmus suspected the manuscript had been produced specifically to answer him.

Legend has it that Erasmus made a rash promise, swearing to print the verse if 1 Greek manuscript could be produced. It makes a wonderful story. Historian Henk Jan de Jonge, however, examined the sources and found no evidence of any such promise. It’s a legend, and we should not use arguments that are untrue even when they help our case.

From Erasmus the words passed into the editions of Robert Stephanus and Theodore Beza, and from those into the Greek text used by the King James translators in 1611. Nothing was concealed along the way. The men of that era knew the reading was contested. They simply had very little material with which to test it.

“But the Greek grammar needs it!”—the best objection, answered

Greek words have a gender. Every noun is either masculine, feminine or neuter—a bit like calling something “he”, “she” or “it”.

Now look at verse 8. The 3 earthly witnesses are the spirit, the water and the blood. In Greek, all 3 of those words are neuter. They’re “its”. But when John introduces them, he doesn’t use the “it” form. He writes “three that testify” using the masculine form, as though he were pointing at 3 men.

That’s odd. So defenders of the Comma say: this oddness is a wound. Something masculine has been cut out of the sentence, and we know exactly what—”the Father” and “the Word”. It’s a clever argument. But it doesn’t survive a close look.

• Greek writers personify things constantly. When things act like persons, they’re spoken of like persons. The 3 are witnesses in a courtroom, and witnesses are people. The masculine form fits the picture.
• John himself breaks the supposed rule 2 verses earlier. In verse 6 he speaks of the Spirit using the neuter. So he’s plainly not bound by any fixed pattern in this passage.
• The decisive answer: the mismatch appears everywhere. Verse 8 reads this way in every manuscript we possess, including the hundreds that never contained the Comma. A feature found in all copies is the author’s style, not a scar left by missing words.
• And it doesn’t even solve the problem. Print the Comma, and verse 8 still uses the masculine for the earthly 3. The supposed cure leaves the supposed disease exactly where it was.

There’s a second problem, and it’s about meaning rather than grammar. Read the passage as a whole:

This is he who came by water and blood—Jesus Christ; not by the water only but by the water and the blood. And the Spirit is the one who bears witness, because the Spirit is the truth. (1 John 5:6, ESV)

John is answering false teachers who denied Jesus Christ truly came in the flesh, in water and in blood. His whole argument is about the testimony borne to Jesus. 3 heavenly Persons testifying about their own unity doesn’t advance that argument. It interrupts it. The passage runs better without the clause, not worse.

What our own forefathers said

Here we must be careful, because the history doesn’t run entirely in our favour.

• John Calvin accepted the clause, but visibly uneasily. In his commentary he observes the Greek copies don’t agree, and says he dare not assert anything about it. He kept it mainly because he thought the sentence read more smoothly with it.
• Theodore Beza printed it in his Greek editions, which shaped the English Bible for centuries.
• Francis Turretin defended its genuineness in his great work of theology.

Should that settle the question? No—and the reason why is important.

Calvin died in 1564. Codex Sinaiticus wasn’t discovered until 1844, and the Syriac, Coptic and Armenian evidence was unavailable to him. He had a handful of late copies and a Latin tradition a 1000 years deep. Given that, his hesitation was remarkably honest.

More importantly, their own principle leads us where we now stand. Rome defended the Comma by pointing to the Latin Vulgate and the authority of the church. The Reformers answered: go back to the original languages, and let the text be judged by the witnesses God has preserved. That’s exactly what we’re doing, with the evidence they longed to have.

The direction of travel in our own tradition is clear. Charles Hodge and BB Warfield defended the full inspiration of Scripture as vigorously as anyone ever has, and both rejected the Comma. Warfield saw no tension. If you believe God gave His very words, you should want those words alone, and no others.

Does this break “kept pure in all ages”?

For many readers this is the real question. The Westminster Confession of Faith says the Scriptures in Hebrew and Greek were “immediately inspired by God, and by His singular care and providence kept pure in all ages”. The same words appear in the Baptist Confession of 1689.

Some argue this must mean the printed Greek text of the Reformation era is flawless, so the Comma must be genuine; remove it, and the Confession falls. Read the sentence again slowly. It doesn’t say what that argument needs it to say.

The Confession makes a promise about God’s care over the whole stream of copies. It never names Erasmus, Stephanus or Beza, and it never declares a printing house infallible.

3 points make this plain.

• The men who wrote the Confession knew about variant readings. The Stephanus edition of 1550, sitting on their desks, printed a margin listing Greek copies that lacked this very verse. They knew, and they didn’t conclude purity had failed.
• Historian Richard Muller has shown 17th-century theologians never claimed one printed edition was flawless. They spoke of the text preserved in the copies taken together—a body of evidence, not one book on one shelf.
• If one printed edition were perfect, which one? Those editions differ from each other in hundreds of places, and several don’t contain this verse at all. We must still choose—and choosing between copies is the very activity the objection was meant to forbid.

Preservation promises that God keeps His Word safe for His church. It doesn’t promise He does so through one printer in one century.

The doctrine doesn’t need the verse

Now to the heart of it. Many believers fear losing 1 John 5:7 weakens the Trinity. It doesn’t weaken it by a gram.

All quotations are from the ESV. Remove 1 John 5:7 and every line of this table stands untouched.

Then there’s the historical argument, which is the strongest of all. The Nicene Creed was written by men who’d never seen the Johannine Comma. The doctrine of the Trinity was defined and secured in Greek, by pastors reading Greek Bibles without this clause, in the middle of the most savage doctrinal conflict in Christian history. They won without it.

So why is this argument back in the news?

Because two quite different revivals of interest are happening at once, and they’re often confused with each other.

In the universities

Grantley McDonald’s study Biblical Criticism in Early Modern Europe (Cambridge University Press, 2016) traced the whole social and political history of this clause—Erasmus, Luther, Calvin, Isaac Newton and the rest. Meanwhile a vast new critical edition of the Greek letters has given this generation more information about the text of 1 John than any before it. The academic verdict hasn’t softened. It has only hardened.

In the churches

A movement often called Confessional Bibliology argues the churches of the Reformation received a particular Greek text, and that our doctrine of preservation obliges us to keep it. Around it have grown conferences and books: “Kept Pure in All Ages” in Wisconsin in 2022, the ongoing Text and Translation conferences, the Reformation Bible Society conference of 2024, the essay collection Why I Preach from the Received Text edited by Jeffrey Riddle and Christian McShaffrey (2022), and Taylor DeSoto’s The Received Text: A Field Guide (2024).

These aren’t the old, angry King James Only fundamentalism, and it is unfair to treat them as though they were. They’re confessional men, often faithful pastors, making a theological argument about providence. They deserve a serious answer. Here’s that answer, in a single observation.

Note too the pushback isn’t coming from unbelieving scholars. In 2026 Timothy Decker, a Baptist pastor who holds the 1689 Confession, published a detailed series arguing against the Comma and engaging the confessional case directly. This is a conversation inside the family, and it should be conducted that way.

The other reason for renewed interest is simply public exposure. Since textual criticism reached mainstream audiences in 2025, ordinary Christians have begun asking about manuscripts, and the Johannine Comma is almost always their first question. We should be ready with a clear answer.

So, should 1 John 5:7 be in our Bibles?

No. And that answer costs us nothing we should want to keep.

• Nothing is lost. Every doctrine remains. The Trinity stands on dozens of passages, and always did.
• Something is gained. Adding to God’s Word is as serious as taking from it. Moses warned Israel not to add to what God commanded (Deuteronomy 4:2), and the warning closing Revelation cuts both ways. Keeping words God never gave isn’t reverence. It’s presumption dressed as piety.
• Our witness is strengthened. When a Muslim, a sceptic or a cult member says “you Christians invented a Trinity verse”, we no longer have to defend the indefensible. We can say: yes, some Latin Christians added a sentence in about the fourth century; Christian scholars detected it, and Christian publishers removed it. Our doctrine never rested on it for a day.

The scribe who first wrote those words in a margin was trying to help. He believed the Trinity, and he wanted his reader to see it in the text. We can honour his intention and still correct his mistake.

God didn’t need an added sentence to tell us who He is. He told us on every page.
