John 20:24–29 · Thomas · An Iconic Story

The Man Who Asked to Touch

The disciple the world calls “doubting” is the one who says the biggest thing anybody says about Jesus in all four gospels — and he says it without touching anything.

THE ARTWORK

Caravaggio does the one thing the text never does: he takes Thomas by the wrist and guides the finger in, and three heads lean over the wound to watch it happen. It is magnificent, and it is an addition: John records the offer and the answer, and never records the touch. The painting is this page's own exhibit: four centuries of Christian imagination filling a silence the gospel left open on purpose.

He Missed the One Night That Mattered

John 20:24–29, told plainly

On the evening of the first Easter the disciples were shut in a room with the doors locked, and Jesus came and stood among them and showed them His hands and His side. Thomas was not there. John does not say why. Nobody does.

It was the first day of the week, and that very evening, while the disciples were together with the doors locked for fear of the Jews, Jesus came and stood among them. “Peace be with you!” He said to them. After He had said this, He showed them His hands and His side. The disciples rejoiced when they saw the Lord.
John 20:19–20BSB

The ten get the wounds shown to them first, and only then does the text say they were glad.

When Thomas came back they told him what had happened, and he would not have it. He named his terms, and he named them precisely: unless I see the nail marks in His hands, and put my finger where the nails have been, and put my hand into His side, I will never believe.

Now Thomas called Didymus, one of the Twelve, was not with the disciples when Jesus came. So the other disciples told him, “We have seen the Lord!” But he replied, “Unless I see the nail marks in His hands, and put my finger where the nails have been, and put my hand into His side, I will never believe.”
John 20:24–25BSB

The most specific sentence in the chapter, and the words for “nail” and “mark” in it occur almost nowhere else in the New Testament.

Eight days later they were in the room again, and the doors were shut again, and Jesus came and stood among them again. He went straight to Thomas and handed him, word for word, the exact test he had asked for: put your finger here; look at My hands. Reach out your hand and put it into My side. Stop doubting and believe.

Then Jesus said to Thomas, “Put your finger here and look at My hands. Reach out your hand and put it into My side. Stop doubting and believe.”
John 20:27BSB

Jesus quotes Thomas's own demand back to him. He had not been in the room when it was said.

John never says Thomas touched anything. What John records is what Thomas said: My Lord and my God. And then Jesus said the sentence that reaches straight out of that room and finds everyone who has ever read the page: because you have seen Me, you have believed; blessed are those who have not seen and yet have believed.

Six Places the Retelling Drifts

what the text actually says, against what the story has become

It is not known what was the ground of the incredulity of Thomas. It is probable, however, that it was, in part, at least, the effect of deep grief… Thomas has been much blamed by expositors, but he asked only for proof that would be satisfactory in his circumstances.

Albert Barnes· Notes, Explanatory and Practical, on the Old and New Testaments (1832-1869), on John 20:25

“DOUBTING THOMAS” IS NOT IN THE BIBLE

The phrase appears nowhere in Scripture. The first thing John ever records Thomas saying is “Let us also go, that we may die with Him”: spoken when returning to Judea was likely to get the whole group killed, and spoken when nobody else would say it. The nickname flattens a brave man into one bad week.

John 11:16

HE IS NOT THE ONLY ONE WHO DOUBTED

The other ten had needed the same evidence eight days earlier: verse 20 says Jesus showed them His hands and His side, and only then were they glad. Mark's gospel says He rebuked them all for not believing those who had seen Him. Thomas is remembered for it because he said it out loud.

John 20:20

THE TEXT NEVER SAYS HE TOUCHED

It says Jesus offered, and it says Thomas answered. Between the offer and the answer John writes nothing at all. The single most famous detail in the story: the finger in the wound: is the one thing the gospel declines to record, and readers have noticed since the fourth century.

John 20:28

THE RISEN BODY STILL HAD THE WOUNDS

A common assumption is that a glorified body would be unmarked. He kept them. He kept them through eight days, and He carried them into a room with the doors shut, and He offered them as evidence. The scars are not left over from the cross; they are being used.

John 20:27

“MY LORD AND MY GOD” IS NOT AN OUTBURST

It is sometimes read as shock: words thrown at heaven rather than spoken to Jesus. John blocks that reading in the sentence itself: Thomas answered and said to Him. It is addressed. And the reply is not a correction but a blessing.

theos: God

VERSE 29 IS A BLESSING, NOT ONLY A REBUKE

Jesus does say “because you have seen Me, you have believed.” Then He turns and blesses everybody who never will see: the only beatitude in John's gospel, aimed at people who were not in the room. Every reader of this page is inside that sentence.

John 20:29
For though of Thomas alone is recorded the saying: Except I shall put my hands and see the prints of the nails, and put my hand into His Side, I will not believe, yet was the charge of lack of faith common to them all; and we shall find that the minds of the other disciples were not free from perplexity, though they said unto the holy Thomas: We have seen the Lord.

Cyril of Alexandria· Commentary on the Gospel of John, Book 12 (444), on John 20:28

A Twin, Two Nails, and Eight Days

the details the first readers had, and the ones that came later

John introduces him twice over as Thomas, called Didymus — and both names mean the same thing. Thomas is Aramaic for twin; Didymus is the Greek for twin. The man is named Twin in two languages, and the gospel never tells us whose twin he was. It is the only name in John that gets translated for the reader.

His demand is the most precisely worded sentence in the chapter, and its vocabulary is almost unique in the New Testament. The word for nail occurs exactly twice in the whole of it: both times inside this one verse. The word for the mark a nail leaves occurs twice in the same verse. Thomas is not waving at the resurrection in general terms. He is asking for a specific wound, in a specific place, on a specific body.

Why eight days, and why that day?

Jewish reckoning counts inclusively, so “after eight days” is our “a week later” — John Gill works this out on the verse in his Exposition of the New Testament, citing Josephus by way of Henry Hammond for the idiom. That places the second appearance on the next first day of the week, the same day as the first. Later Christian writers took that pattern as the seed of the Lord's Day; that is how the church has read it, and it is reception history, not a claim the passage makes.

For what reason does the Lord appear to him not immediately, but after eight days? So that he, heeding the instruction of his fellow disciples and hearing the same thing, would be inflamed with greater desire and become firmer in faith for the future.

Theophylact of Ohrid· Commentary on John (1107), on John 20:26

The doors were shut: both times

Verse 19 and verse 26 both note the shut doors, and the repetition is doing work: the same body that walks through a locked room is the body with holes in it. The risen Christ is not a ghost who cannot be touched, and He is not a man who needs the door opened. Augustine answered the physics question in one sentence, roughly sixteen centuries ago:

You ask; If He entered by the shut door, where is the nature of His body? … And I reply; If He walked on the sea, where is the weight of His body? The Lord did that as the Lord; and did He, after His resurrection, cease to be the Lord?

Augustine of Hippo· Catena Aurea by Aquinas (1264), on John 20:26

Thomas in India

The tradition that Thomas carried the gospel east to India is early, and it is held to this day by the Saint Thomas Christians of Kerala, who trace their churches to his preaching. It is worth knowing and worth honouring. It is also tradition, not Scripture: the New Testament never says where Thomas went. Acts lists him in the upper room in chapter 1 and never mentions him again. This page names the tradition, marks it as tradition, and stops there.

The Three Conditions, and What the Text Records

the checklist the gospel refuses to tick

Thomas set three terms. Jesus met him on every one of them out loud, and then John's pen stops. Here is the demand of verse 25 laid beside what the chapter actually puts on the record.

First condition

“Unless I see the nail marks in His hands…”

Jesus offers it, word for word: “Look at My hands” (v.27). This one the text does grant: Thomas sees.

John 20:27
Second condition

“…and put my finger where the nails have been…”

Jesus offers it: “Put your finger here.” John never writes that Thomas did. No touch is recorded.

John 20:25
Third condition

“…and put my hand into His side, I will never believe.”

Jesus offers this too: “Reach out your hand and put it into My side.” Again: no touch is recorded.

John 20:28

What John records instead: verse 28

“My Lord and my God!”

The gospel records the demand, and it records the offer, and it records the answer. It never records the touch.

Thomas answered and said unto him, My Lord and my God--That Thomas did not do what Jesus invited him to do, and what he had made the condition of his believing, seems plain from Joh 20:29 ("Because thou hast seen Me, thou hast believed"). He is overpowered, and the glory of Christ now breaks upon him in a flood.

Jamieson, Fausset & Brown· Commentary Critical and Explanatory on the Whole Bible (1871), on John 20:28

He saw and touched the man, and acknowledged the God whom he neither saw nor touched; but by the means of what he saw and touched, he now put far away from him every doubt, and believed the other… Although it may be affirmed that the disciple dared not so to touch, when He offered Himself for the purpose; for it is not written, And Thomas touched Him.

Augustine of Hippo· Tractates on John 121 (430), on John 20:27-29

A note on honesty: the gospel does not say Thomas refrained, either. It simply does not say. Some of the oldest readers of this chapter concluded he never touched; others assumed he did. This page reports the silence and leaves it standing, because that is what the text does.

Christ and Doubting Thomas — Carl Bloch, 1882

THE ARTWORK

Set this beside the Caravaggio at the top of the page. Bloch paints the same moment and keeps the hands apart: Christ opens His robe and shows the wound, and Thomas is left facing it with nothing resolved for him by anyone else's grip. Two great painters, two centuries apart, filling the same gap in opposite directions, which is exactly how a silence in a text behaves once it leaves the page.

Carl Bloch, Kristus og den vantro Thomas (Christ and Doubting Thomas), 1882, Statens Museum for Kunst. CC0, via Wikimedia Commons.

Why was Thomas not there?

John gives one clause and no reason: he was not with them when Jesus came. Ancient commentators guessed: Chrysostom and Theophylact both suppose the disciples had scattered and he had not yet come back, and they are guessing, and they say so. The gospel offers no explanation, no rebuke for the absence, and no excuse for it. What it shows is the cost: the one man who missed the room spent eight days hearing about it from everybody who had been in it.

What did those eight days hold?

Not a word. We are told what the ten said to him once: we have seen the Lord — and we are told what he answered. Whatever was said between them over the following week, whatever he did with it, whether anyone argued or let him be: the text is blank, and it stays blank. He is in the room the next time. That is the only thing we know about the eight days.

What became of Thomas afterwards?

He appears at the Sea of Galilee in John 21, and he is listed among the eleven in the upper room in Acts 1:13, and then the New Testament says nothing more about him. The India tradition, above, is the church's memory and not the Bible's record. The last words Scripture puts in his mouth are the ones on this page.

The Biggest Sentence in the Four Gospels

what verse 28 says, spoken to His face and not refused

Thomas replied, “My Lord and my God!”
John 20:28BSB

Not narrated about Him: spoken to Him, by name, and answered with a blessing.

Weigh what happens here. Elsewhere in Scripture, when men are worshipped they recoil from it: Paul and Barnabas tear their clothes at Lystra and shout that they are only men; the angel in Revelation twice orders John off his knees. Jesus does neither. A disciple calls Him my God to His face, and the reply is not a correction: it is a beatitude.

My Lord and my God - In this passage the name God is expressly given to Christ, in his own presence and by one of his own apostles… 3. The Saviour did not reprove him or check him as using any improper language. If he had not been divine, it is impossible to reconcile it with his honesty that he did not rebuke the disciple. No pious man would have allowed such language to be addressed to him. Compare Act 14:13-15; Rev 22:8-9.

Albert Barnes· Notes, Explanatory and Practical, on the Old and New Testaments (1832-1869), on John 20:28

Let them therefore confess, even they who previously denied that the crucified was God, that they have erred. For the divine Scriptures bid them, and especially Thomas, who, after seeing upon him the print of the nails, cried out, "My Lord and my God."

Athanasius of Alexandria· LETTER 59.10, TO EPICTETUS (373), on John 20:28

Was it just an exclamation?

The reading that treats “My Lord and my God” as words thrown at heaven in shock is not new: it goes back at least to Theodore of Mopsuestia in the fifth century, and the church councils dealt with it directly. Adam Clarke lays out the history, and the grammar settles it before the history does: John writes that Thomas said it to Him.

Those who deny the Godhead of Christ would have us to believe that these words are an exclamation of Thomas, made through surprise, and that they were addressed to the Father and not to Christ. Theodore of Mopsuestia was the first, I believe, who gave the words this turn; and the fifth Ecumenic council, held at Constantinople, anathematized him for it.

Adam Clarke· Commentary on the Bible (1832), on John 20:28

In the beginning was the Word, and the Word was with God, and the Word was God.
John 1:1BSB

The gospel opens by telling the reader who He is…

…and closes with a man saying it to His face. Verse 28 is where the book's first sentence lands. Everything between the two is the argument.

That which was from the beginning, which we have heard, which we have seen with our own eyes, which we have gazed upon and touched with our own hands—this is the Word of life.
1 John 1:1BSB

The same writer, years later, still reaching for the language of hands and eyes.

Jesus performed many other signs in the presence of His disciples, which are not written in this book. But these are written so that you may believe that Jesus is the Christ, the Son of God, and that by believing you may have life in His name.
John 20:30–31BSB

John's statement of why the whole book exists stands two verses after Thomas, and uses the same verb: believe.

The connection of these verses with the last words of Joh 20:29 is beautiful: that is, And indeed, as the Lord pronounced them blessed who not having seen Him have yet believed, so for that one end have the whole contents of this Gospel been recorded, that all who read it may believe on Him, and believing, have life in that blessed name.

Jamieson, Fausset & Brown· Commentary Critical and Explanatory on the Whole Bible (1871), on John 20:29

What if, then, the Lord had risen without scars? Indeed, could he not have resurrected his flesh, so that no traces of wounds would remain in it? He could have done this; but unless he had retained the scars on his body, he would not have healed the wounds in our heart… But when he revealed to him what had remained doubtful, he exclaimed: My Lord and my God. He was touching the flesh, and he was calling out to the divinity.

Augustine of Hippo· Sermon 145A (430), on John 20:28

That is the hinge of the whole scene: He kept the scars. The risen body that walks through a locked door still carries the holes, because the wounds were never an accident to be healed over: they are the evidence He came back to show.

How the Church Has Read This Room

the oldest readers, on the doubt that helped everybody else

Thomas's unbelief did more for us than the others' faith

Gregory preached this chapter as a mercy rather than a failure: the one disciple who had to be convinced is the reason the rest of us are not left guessing. It is the oldest and warmest reading of the story, and it turns the nickname inside out.

For heavenly mercy acted in a wondrous way so that the doubting disciple, while he touched the wounds of flesh in his master, might heal in us the wounds of unbelief. For the unbelief of Thomas profited us more for faith than the faith of the believing disciples, because while he is brought back to faith by touching, our mind, all doubt set aside, is strengthened in faith.

Gregory the Dialogist· Forty Gospel Homilies, Homily 26 (604), on John 20:24

Why the marks stay

Augustine took the kept scars of John 20 and reasoned outward to the martyrs: a mark carried for Christ is not damage but honour. The passage is his, not the gospel's: the text says only that Jesus kept His own wounds and used them: but it shows how early readers understood what those wounds were doing on a glorified body.

The love we bear for the blessed martyrs causes us—how, I do not know—to desire to see in the heavenly kingdom the marks that they received for the name of Christ. And possibly we shall see them. For this will not be a deformity but a mark of honor… For even though the blemishes of the body will not be found in any resurrected body, the evidences of virtue can hardly be called blemishes.

Augustine of Hippo· City of God 22.19 (430), on John 20:27

The blessing, aimed forward

Leo read verse 29 the way it is written: as a sentence about the people who would come after, believing on testimony rather than sight. It is the earliest preaching of this page's own point: the beatitude is not a consolation prize for missing the room.

It is the strength of great minds and the light of firmly faithful souls unhesitatingly to believe what is not seen with the bodily sight and to focus your affections where you cannot direct your gaze… And so, our Lord said to Thomas, who seemed to doubt Christ's resurrection until he had tested by sight and touched the traces of his passion in his very flesh, "because you have seen me, you have believed; blessed are those who have not seen and yet have believed."

Blessed Are They That Have Not Seen

Jesus said to him, “Because you have seen Me, you have believed; blessed are those who have not seen and yet have believed.”
John 20:29BSB

The only beatitude in John's gospel, and it is spoken past Thomas, to the reader.

The scene ends with Jesus looking straight out of it. Thomas got the evidence he asked for, and the gospel does not begrudge him a second of it, but the last word of the episode is a blessing on everyone who would come afterward with nothing but the testimony of the people who were there. Two verses later John says that is exactly why he wrote the book. The man who demanded proof is the reason the rest of us have a record, and the sentence he was given is addressed to whoever is reading now.

If, like a Thomas, you were left out when the disciples were assembled to whom Christ shows himself, when you do see him do not be faithless. And if you do not believe, then believe those who tell you. And if you cannot believe them either, then have confidence in the print of the nails.
