Thomas, called Didymus, the Twin, is remembered above all as Doubting Thomas, the apostle who would not believe in the Resurrection until he had placed his fingers in the wounds of the risen Christ, and who then confessed, My Lord and my God. Earlier he had bravely urged the others to go with Jesus to die with him. Tradition carries him east to preach in India, where the ancient Saint Thomas Christians revere him as their founder, and holds that he was martyred with a spear. As archetype he is the seeker of proof and truth, who reminds us that honest doubt can deepen into the firmest faith.

Facts
Origins
Founded
The apocryphal Acts of Thomas credits him with carrying Christianity to India, where the Saint Thomas Christians of Kerala trace their founding to his mission. 2
Origin of the Name
His name Thomas and his Greek epithet Didymus both mean twin, a doubled naming the canonical Gospels never explain by identifying his twin, though later apocryphal tradition, including the Acts of Thomas, elaborates various identities for the missing sibling. 2

Doubt, and What the Scene Is Actually About

Thomas is remembered for a single episode and for an adjective the episode does not use.

In John, and only in John, Thomas is absent when the risen Jesus appears to the other disciples, refuses their testimony, and says he will not believe unless he puts his finger into the nail wounds and his hand into the side. A week later Jesus appears again and invites him to do exactly that. The text does not say whether he did. What it records is his answer, my Lord and my God, which is the highest christological confession any character makes in that Gospel and the point the scene was written to reach.

The phrase doubting Thomas is not in the passage. The Greek has Jesus tell him to stop being unbelieving and become believing, and the term rendered doubt in most English versions is a translator's choice. Reading the episode as a rebuke of scepticism is a later Christian usage; reading it as the climax of John's argument about who Jesus is fits the text better.

Thomas has two other appearances in John, and both cut against the caricature. When Jesus proposes returning to Judaea where the authorities have tried to stone him, it is Thomas who says, let us also go, that we may die with him. And it is Thomas who interrupts the farewell discourse to say that they do not know where Jesus is going, which prompts the answer about the way, the truth and the life. In the synoptic Gospels he is a name in a list and nothing more.

The name is not a name. Toma is Aramaic for twin, and John glosses it with the Greek Didymos, which also means twin. Whose twin, the canonical texts do not say.

The Thomas Literature and the Indian Church

That unexplained epithet is the seed of a large body of later writing, none of which is by him.

The Gospel of Thomas, recovered complete in Coptic at Nag Hammadi in 1945 with Greek fragments long known from Oxyrhynchus, is a collection of one hundred and fourteen sayings with no narrative, no passion and no resurrection. Its opening line attributes it to Didymos Judas Thomas. Dating is contested along a wide range: some scholars place a core in the first century, potentially independent of the canonical Gospels, while others date the collection as we have it to the mid second century and read it as dependent on them. Both positions are held by serious people and the question is not settled.

The Acts of Thomas, a third-century Syriac romance, makes the twin explicit and startling: Thomas is the twin brother of Jesus. It also supplies the narrative of his mission to India, his conversion of a king named Gundaphorus, and his death by spearing near Mylapore. A king of that name is real, Gondophares, an Indo-Parthian ruler of the first century, is attested on coins and in an inscription, which is a genuine and unexpected point of contact, though it establishes only that the author knew a real name.

The Saint Thomas Christians of Kerala are an ancient community, and Christianity in south India is attested well before European contact. Their tradition of apostolic foundation by Thomas in 52 CE is central to their identity and is not archaeologically demonstrable. What can be said is that the community is old, the claim is old, and the evidence does not extend to the first century.

Attributed Works

Why this is disputed. The text itself names Didymus Judas Thomas as the one who wrote down these sayings of the living Jesus, invoking the apostle traditionally linked with Syriac Christianity. Scholars overwhelmingly reject the apostolic ascription as a pseudepigraphic framing device rather than a historical claim, and date the actual compilation anywhere from the mid first to the mid second century depending on how independently its sayings are judged to derive from the same tradition behind the canonical Gospels versus how dependent they are on those Gospels themselves, a question still actively debated among specialists.

Jesus, Figures

Thomas's own description article: "The Acts of Thomas, a third-century Syriac romance, makes the twin explicit and startling: Thomas is the twin brother of Jesus." Named to that specific text, which the article does not dispute. A studied-by edge already connects Thomas and Jesus for the discipleship, a distinct fact from this one.
