Short answer: Luke 6:16 names Judas the son of James as one of the twelve Jesus chose, listed immediately before Judas Iscariot, who is identified as the one who became a traitor. The verse distinguishes the two men by father and by outcome, not by anything this Judas said or did. Beyond his selection, the Gospel of Luke records no words, actions or later scenes for him. He is known to Jesus and named by him, and that is the whole of what this verse supplies.
A name in a list on a mountainside
Luke 6:16 sits inside a roster, not a story. Jesus has spent the night on a mountain in prayer, and when morning comes he calls his disciples and chooses twelve of them to be a distinct group. Luke then writes their names in a terse, formulaic line, running from Simon Peter through pairs of brothers and companions, and ending with two men both called Judas. The second Judas is marked at once as the one who became a traitor. The first, Judas the son of James, receives no description at all. He is simply a name in a list, and the list is the point.
The placement matters. This roster stands between the choosing on the mountain and the descent to a level place, where a crowd from Judea, Jerusalem, and the coast of Tyre and Sidon gathers to hear Jesus and be healed of their diseases. The twelve are named, and then they go down with him into public ministry. Luke 6:17 shows the crowd waiting below, including people troubled by unclean spirits who were being healed. So the list is not an aside. It introduces the men who accompany Jesus into that scene, named before anything they say or do is recorded.
The shape of the ending is worth noticing. Two Judases close the list, and only the second is annotated with betrayal, which casts a shadow forward toward the passion. The first Judas is left unelaborated, and Scripture does not fill in his later life. His obscurity is not evidence of failure, and his selection is not a promise of earthly success. What the text gives is a name among twelve men chosen after a night of prayer, standing on a level place with Jesus while the crowds came to hear and be healed.
He came down with them, and stood on a level place, with a crowd of his disciples, and a great number of the people from all Judea and Jerusalem, and the sea coast of Tyre and Sidon, who came to hear him and to be healed of their diseases;
Two men named judas, set apart by the text
Luke 6:16 names a disciple as "Judas the son of James". The name Judas was common in first-century Judea, so a bare name would not tell a reader which man was meant. Luke identifies him the ordinary way, by his father. This is the only place in the Gospels where this disciple is named, and nothing else is recorded about him. He is not the Judas who kept the money bag, and he is not the Judas of Iscariot. The text gives us a name and a father and then moves on, and that is all the passage says about him.
The same verse then names the second man: "and Judas Iscariot, who also became a traitor." Luke places the two side by side and marks the difference in a single clause. The word traitor describes what Iscariot became; it is not attached to the first Judas. Notice the wording: he became a traitor, which speaks of a course taken rather than a role assigned at the start. The verse does not explain how or why, and it does not apply the word to anyone else in the list.
The setting matters for how we read the names. Luke 6:17–18 shows Jesus coming down with these men to a level place, where a crowd from Judea, Jerusalem, Tyre and Sidon gathered to hear him and be healed. The twelve are named as those who came down with him, yet most of them, this Judas included, are never heard from again in the story. Scripture does not tell us how he lived or died, and his silence in the record is not evidence of failure. Being named by Jesus was not a promise of prominence, and it was not a guarantee of ease.
The verse also keeps us from reading the list as a ranking. Two men share a common name, and the text distinguishes them by father and by what one of them became. That is a small, careful detail, and it is worth noticing: the Gospel writers take pains to say exactly who is who. The first Judas is given a place among the twelve and left there, named and known to Jesus, with nothing more said.
Judas the Son of James: named among the twelve
Luke 6:16 ends the list of the twelve with two men who share a name: "Judas the son of James; and Judas Iscariot, who also became a traitor." The first Judas is identified only by his father, James. No trade, town, nickname, or later scene is attached to him here. That bareness is worth noticing. Luke, who elsewhere delights in small details, gives this disciple nothing to remember him by except that Jesus chose him and named him. The verse's plain claim is that he belonged among the twelve, and that his identity is bound up with his father's name rather than with anything he did.
The list sits at the end of a sequence. Jesus withdrew to a mountain to pray, then called his disciples and chose twelve from among them, and Luke names them in pairs before moving straight into the next scene. Immediately after the list, Jesus comes down with them and stands on a level place, where a crowd from Judea, Jerusalem, and the coast of Tyre and Sidon gathers to hear him and be healed. The twelve are introduced, then they descend with Jesus into public ministry. Judas the son of James is part of that company from the start, not a later addition to the story.
The verse holds both Judases together, and the contrast does the work. One is known only as James's son; the other carries the note that he became a traitor. Luke places that shadow at the close of the list, pointing ahead toward the passion without explaining it. Yet the first Judas receives no such comment, good or bad. Scripture does not tell us what became of him, and we should not fill the silence with guesses about failure or success. What stays central is that Jesus chose him, named him, and sent him down the hill with the others.

Where readers differ about judas the Son of James
The first question careful readers ask is whether this Judas is the same man as Thaddaeus. Matthew and Mark list the Twelve and include Thaddaeus, while Luke lists Judas the son of James in that same slot near the end. Some conclude these are two names for one disciple, perhaps a formal name and a family or nick name, and they point to the shared position in the lists. Others are less sure, noting that Luke elsewhere gives both names for Simon, and that no Gospel explains the connection. The text itself supplies only a name and a father's name. Everything beyond that is inference, not exposition.
A second question concerns John 14:22, where a Judas, not Iscariot, asks Jesus how he will reveal himself to the disciples and not to the world. Some readers identify that questioner with Judas the son of James, since John has already distinguished him from the betrayer. Others hold back, because John gives no father's name and never links this Judas to the apostolic lists. The disagreement is honest and unresolved. What the passage in Luke fixes is narrower and firm: Jesus chose twelve, this Judas was among them, and Luke carefully marks him off from Judas Iscariot, the traitor.
A third area of difference is how much weight to give later traditions about this Judas's preaching and death. Some read them with interest; most evangelicals treat them as unverified and decline to build teaching on them. The silence of Scripture about his later life is not evidence that he failed, and his selection is not a promise of earthly safety or success. What stays central across these views is the same: the Lord gathered twelve to himself, this obscure man was one of them, and his story is held by the one who called him.
Named by Jesus among the twelve
Luke 6:16 lists this Judas almost in passing, distinguishing him from Judas Iscariot by naming his father, James. The verse gives no miracle, no speech, no failure. Yet the setting matters: Luke has just recorded that Jesus chose these men from his disciples and named them apostles (6:13–16). This Judas did not volunteer for a prominent role or earn a place by reputation. He was named by Christ. That is the ground of his identity in the story, and it is the ground of every disciple's identity. The gospel begins with Jesus calling ordinary people, not with impressive people assembling around a worthy teacher.
The same verse holds two names side by side: Judas son of James, and Judas Iscariot, who became a traitor. Luke does not soften the pairing. Jesus knowingly called both, and he did not build a community of the flawless. The band contained faithfulness and betrayal from the start, which keeps the cross in view before the story reaches it. Being chosen by Christ never meant the twelve were safe from failure or exempt from the world's darkness. It meant they were with him, taught by him, and sent by him, and that is where the gospel meets us too.
Nothing in Scripture tells us what this Judas did afterward. His obscurity is not evidence of failure, and his selection is not a promise of earthly success or safety. What the text does say is enough: Jesus named him, taught him, and sent him with the others. A disciple's identity rests on Christ's call, not on the record of deeds, remembered or forgotten. That is grace, and it is the same grace that reaches us. The one who called this obscure Judas still gathers unknown people into his service and holds them in his purposes.
Judas the Son of James and the faithful who go unnamed
Read the list of the twelve slowly and count how little the Gospels tell us about most of them. Luke gives us Judas the son of James in a single line, and then the record moves on. We are not told where he preached, what he suffered, or how he died. Scripture simply does not say, and it is worth resisting the urge to fill the silence. What the text does say is that Jesus named him among the twelve. That is the whole of his commendation here, and it is enough to make us ask whether we measure our own discipleship by visible results or by the fact that Christ has called us.
Notice, too, that being numbered among the twelve was never a promise of ease. The same list ends with Judas Iscariot, who became a traitor, and the rest of these men met hardship and, by tradition, violent deaths. Nothing in this verse guarantees safety, success, or a reputation that outlives us. So the pairing of the two Judases should press us toward honest self-examination rather than complacency. Am I following Jesus for what he gives, or for himself? And do I resent obscurity, when grace rather than reputation is what holds a disciple secure?
Then let this line move you to prayer for the unnoticed faithful in your own church: the one who sets out chairs, teaches a small class, visits the sick, and is never named from the front. Their service is recorded before God even when the record here below is thin. Ask him to keep you faithful in ordinary, uncelebrated obedience, and to guard your heart from measuring worth by applause. Judas the son of James was called, and so are you. Pray for those who serve beside you without notice, and give thanks that grace, not fame, keeps them.
Biblical fidelity check
Luke 6:16 names two men called Judas, and the careful reader must keep them apart. The first is identified only by his father, James, a plain way of distinguishing him from the other Judas in the same sentence. Luke then adds that Judas Iscariot became a traitor, so the betrayal is tied to one man, not both. Any fuller biography of Judas son of James is inference, not exposition, because the verse supplies a name and a father's name and nothing more.
Evangelical readers differ over whether this Judas is Thaddaeus in the lists of Matthew and Mark, and some link him to the Judas who questions Jesus in John 14. Others hold that the lists simply vary in naming and that certainty is not available. Later traditions about his ministry and death are usually treated as unverified. What stays central is that Jesus chose twelve, that this Judas was among them, and that he is not the betrayer.
Studies that take up Luke 6:16 from another angle
To see how the twelve are listed elsewhere and where the names differ, compare Luke 14: Humility, Invitation, and Discipleship and Luke 1: Births Foretold and Songs of Praise. For the wider setting of the choosing and the sermon that follows, read Luke 11: Prayer, Light, and Woes, and for the same disciple named in another Gospel, see Luke 12: Fear, Treasure, and Readiness.
Frequently asked questions
Is Judas son of James the same person as Thaddaeus?
Scripture never states that they are the same man, so the identification is a long-standing inference rather than something the text says. Luke and Acts list a Judas son of James among the twelve, while Matthew and Mark list a Thaddaeus in the same position in their lists. Because the lists otherwise line up closely, many readers have concluded these are two names for one disciple, but Luke 6:16 itself gives no such equation. What stays central is that the twelve were chosen and named by Jesus, whichever name a given Gospel uses.
Why does the Bible mention two different men named Judas among the twelve?
Judas was a common Jewish name in the first century, so two of the twelve sharing it is unsurprising. Luke 6:16 lists them back to back and adds distinguishing details so readers do not confuse them: one is identified by his father James, the other by the town name Iscariot and by the note that he became a traitor. The Gospel writer is not commenting on the name itself but making sure the faithful disciple and the betrayer are not merged into one person. The same care appears in John, where the disciple is called Judas, not Iscariot.
What do we actually know about Judas son of James from Scripture?
From Luke 6:16 we know only that he was one of the twelve and that his father was named James. Luke gives him no speeches, no miracles and no scenes after the list, and the verse does not record his later life or death. That silence should be respected rather than filled in with tradition or speculation. His obscurity is not evidence of failure, and his selection is not a promise of earthly success; it is a record that Jesus chose him and knew him by name.
