This Quick Facts poster examines one of the New Testament's most debated verses—John 20:28. By comparing Thomas' statement with Jesus' teachings about the Father, John's conclusion in John 20:31, and the wider testimony of Scripture, the study encourages readers to examine the whole biblical context before reaching a conclusion.

Jesus declared the Shema—"Hear, O Israel: Yahweh is our God; Yahweh is one" (Deuteronomy 6:4)—to be the greatest commandment ever given (Mark 12:29). This study examines why this confession stood at the heart of Israel's faith, why God commanded His people to remember it daily, and what it teaches Christians today about the one true God and true worship.
"The foremost is, 'Hear, O Israel: The Lord our God, the Lord is one.'"
— Jesus Christ, Mark 12:29
Throughout history, countless books have been written about God.
Churches have debated doctrine for centuries. Councils have formulated creeds. Scholars have produced volumes of theological works, and millions of Christians have inherited beliefs that have been passed down from generation to generation.
Yet before we ask what later traditions taught, there is a far more important question.
What did God Himself reveal about His own identity?
And what did Jesus Christ declare to be the greatest commandment ever given?
Surely, if there is one teaching that every believer should know, understand, and obey above all others, it must be the commandment that both God and His Son placed above every other commandment recorded in Scripture.
Remarkably, many Christians can quote verses about grace, faith, forgiveness, salvation, or eternal life. Yet comparatively few stop to consider the commandment that Jesus Himself described as the foremost of all.
That alone should cause every sincere student of the Bible to pause and ask an important question:
If Jesus called this the greatest commandment, why is it so rarely discussed today?
This study is not an attempt to defend tradition, nor is it an attempt to attack tradition.
Its purpose is much simpler.
It is an invitation to begin where both God and Jesus began.
To allow Scripture to speak for itself.
To compare Scripture with Scripture.
And to examine whether our own beliefs truly rest upon the foundation laid by God Himself.
More than three thousand years ago, as the people of Israel prepared to enter the Promised Land, God gave them a command unlike any other.
This was not simply another law among hundreds of commandments.
It became the very foundation of Israel's worship, identity, and relationship with God.
Moses declared:
"Hear, Israel: Yahweh is our God; Yahweh is one."
— Deuteronomy 6:4 (WEB)
These words became known as the Shema, from the opening Hebrew word meaning "Hear" or "Listen."
But this was far more than a sentence to memorise.
It was God's own declaration of who He is.
Immediately afterwards, God commanded His people:
"You shall love Yahweh your God with all your heart, with all your soul, and with all your might. These words, which I command you today, shall be on your heart. You shall teach them diligently to your children, and shall talk of them when you sit in your house, when you walk by the way, when you lie down, and when you rise up."
— Deuteronomy 6:5–7
Notice the extraordinary emphasis.
God did not simply tell His people to remember these words.
He commanded that they should be written upon their hearts.
Parents were instructed to teach them diligently to their children.
Families were to speak about them throughout the day.
They were to remember them when they rose in the morning and before they lay down at night.
Why would God place such extraordinary importance upon one commandment?
The answer becomes clear as we read the rest of the Old Testament.
Again and again Israel abandoned the living God and turned to the false gods of the surrounding nations.
The greatest danger facing God's people was not merely moral failure.
It was forgetting who the true God is.
For this reason, God continually reminded Israel of the most fundamental truth they must never forget.
There is only one true God.
Everything else rested upon that foundation.
More than a thousand years later, Jesus Christ was asked one of the most important questions ever put to Him.
A scribe came to Him and asked:
"Which commandment is the greatest of all?"
If there had ever been a moment to replace the commandment given through Moses, this would have been it.
If God's revelation concerning Himself had changed, surely Jesus would have explained it here.
But He did not.
Instead, Jesus immediately returned to the very words spoken by God through Moses centuries earlier.
"The foremost is, 'Hear, O Israel: The Lord our God, the Lord is one.'"
— Mark 12:29
Jesus did not introduce a new commandment.
He reaffirmed the old one.
The same commandment that had stood at the centre of Israel's faith remained, according to Jesus Himself, the greatest commandment of all.
The scribe immediately recognised the importance of Jesus' answer and replied:
"Right, Teacher. You have truly said that He is one, and there is no other besides Him."
— Mark 12:32
Notice carefully what happened next.
Jesus did not correct the scribe.
He did not suggest he had misunderstood.
Instead, we read:
"When Jesus saw that he answered wisely, He said to him, 'You are not far from the kingdom of God.'"
— Mark 12:34
This brief conversation deserves careful reflection.
The greatest commandment was not presented as a mystery.
Neither Jesus nor the scribe entered into a complicated philosophical discussion.
The truth was stated plainly.
It was understood clearly.
And the scribe was commended by Jesus for answering wisely.
If God commanded Israel to place these words upon their hearts...
If parents were commanded to teach them diligently to their children...
If they were to be spoken morning and evening...
If Jesus Himself declared them to be the foremost of all commandments...
Then should they not also stand at the very centre of Christian faith today?
Every Christian, regardless of denomination or tradition, should know this commandment.
Not merely because it appears in the Old Testament.
But because Jesus Himself declared it to be the greatest commandment of all.
That alone should cause us to ask another important question.
If this is the greatest commandment ever given, why do so few Christians study it in depth today?
Perhaps we have become so familiar with these words that we no longer appreciate their importance.
Or perhaps we have simply assumed we already understand them.
Whatever the reason, the greatest commandment deserves far more than a passing glance.
It deserves our careful attention.
Throughout this study we will not ask readers to accept conclusions without evidence.
Instead, we will allow Scripture to interpret Scripture.
We will examine the historical setting.
We will consider the words of Moses, the prophets, Jesus, and the apostles.
We will compare passage with passage.
And we will ask whether the beliefs held by Christians today reflect the foundation laid by God Himself.
Only after establishing that foundation will we begin examining later theological questions.
For there can be no better place to begin than where both God and Jesus began.
With the greatest commandment ever given.
In Part 2, we will examine why God commanded Israel to repeat these words continually, why this declaration became the very heart of biblical worship, and why understanding its historical setting is essential before we examine any later doctrinal questions.
A detailed historical research image examining the development of the doctrine of the Trinity, featuring Simon Brown studying the Bible, the Trinity symbol, the Council of Nicaea, and the question of whether later Church Fathers rejected the earlier Jewish understanding that God is One.
For centuries, 1 John 5:7 has been one of the most debated verses in the New Testament. The longer reading found in the King James Version states:
"For there are three that bear record in heaven, the Father, the Word, and the Holy Ghost: and these three are one."
This passage has often been used as one of the strongest biblical arguments in support of the doctrine of the Trinity.
But an important question remains:
Did the Apostle John actually write these words?
Or were they added centuries later?
As Christians, we should follow the example of the Bereans.
"Examine everything carefully; hold fast to that which is good."
— 1 Thessalonians 5:21
And as the Apostle John warned:
"Beloved, do not believe every spirit, but test the spirits to see whether they are from God."
— 1 John 4:1
If a passage has been questioned by scholars for hundreds of years, it deserves careful examination.
The disputed words are commonly known as the Johannine Comma.
The longer reading says:
"...in heaven, the Father, the Word, and the Holy Spirit: and these three are one. And there are three that bear witness in earth..."
Modern Bible translations usually omit these words because most textual scholars conclude they were not part of John's original letter.
Instead, most modern translations simply read:
"For there are three that testify:"
followed by verse 8:
"the Spirit, the water, and the blood; and the three agree."
One of the main reasons is the manuscript evidence.
The Johannine Comma is absent from the overwhelming majority of ancient Greek manuscripts, including the earliest and most important witnesses.
It is also absent from many early Bible translations, including ancient Syriac, Coptic, Armenian, Ethiopic, Arabic and Slavonic manuscripts.
Many respected textual scholars therefore conclude that the longer reading was not part of the original text written by John.
Bruce Metzger, regarded as one of the world's leading New Testament textual critics, concluded that the passage entered the Greek tradition through a marginal note that was later copied into the text.
The evidence is striking.
The longer Trinitarian wording is missing from virtually all early Greek manuscripts.
It only appears in a handful of very late Greek manuscripts, most of which date from the Middle Ages or later.
This explains why many modern Bible translations omit the passage or place it in a footnote.
An interesting example is the NASB Greek Lexicon.
When examining 1 John 5:7, the lexicon simply translates:
"For there are three that testify."
The additional Trinitarian wording does not appear because it is absent from the Greek text being translated.
The same pattern can be seen in many Greek interlinear Bibles.
The Greek text simply reads:
"For there are three that testify."
There is no reference to:
the Father
the Word
the Holy Spirit
within the Greek manuscript tradition on which these editions are based.
Even many conservative Bible commentaries acknowledge the textual problem.
The Jamieson-Fausset-Brown Commentary notes that the disputed words are absent from the oldest Greek manuscripts and appear to have entered the Latin tradition before eventually finding their way into some Greek copies.
Likewise, the Pulpit Commentary concludes that the passage was almost certainly introduced from a marginal note into the Latin Vulgate before later appearing in a small number of Greek manuscripts.
These observations come from commentators who generally hold orthodox Trinitarian beliefs, yet still recognize the textual evidence.
Dr. James White is a well-known evangelical scholar and defender of the Trinity.
Despite strongly defending Trinitarian theology, he acknowledges that the longer reading of 1 John 5:7 was not part of the original Greek text.
His acceptance of this conclusion demonstrates that rejecting the Johannine Comma does not require rejecting the doctrine of the Trinity itself. Many Trinitarian scholars also agree that the passage is not original.
The King James Bible was translated from the Textus Receptus.
The earliest printed editions of the Textus Receptus did not contain the Johannine Comma.
Later editions included it after pressure was placed on Desiderius Erasmus when a Greek manuscript containing the passage was produced. Most scholars believe this manuscript was very late.
Because the King James translators relied largely on these later editions of the Textus Receptus, the longer reading entered the King James Version.
For many Christians, the answer is no.
Even many Trinitarian scholars freely admit the passage is almost certainly not original while continuing to believe in the Trinity based on other passages.
Likewise, Christians who reject the doctrine of the Trinity argue that removing the Johannine Comma simply restores John's original words.
Either way, the question is one of textual history, not merely theology.
Whatever our theological position, Christians should seek the original words of Scripture.
If later additions entered the biblical text, we should not be afraid to acknowledge them.
Truth has nothing to fear from honest investigation.
As Jesus said:
"Seek, and you shall find."
— Matthew 7:7
After studying the manuscript evidence, the Greek text, early Bible translations, and the conclusions of numerous textual scholars—including many who themselves believe in the Trinity—I have concluded that the longer reading of 1 John 5:7, known as the Johannine Comma, was not part of John's original letter.
In my view, the evidence strongly supports the shorter reading preserved in the earliest Greek manuscripts.
For me, this demonstrates the importance of testing every teaching against Scripture and carefully examining the historical evidence rather than accepting traditions without question.
Whether readers ultimately agree or disagree with my conclusion, I encourage everyone to study the evidence personally and prayerfully.
As Jesus said:
"Seek, and you will find."
— Matthew 7:7
