Who the twelve were, how they were connected to one another through family, trade and town, and which of these links the text states, which tradition supplies and which are still inferences.
Jesus chooses the Twelve
RoleStated in the textJesus selected twelve from his wider group of disciples and named them apostles. The four lists (Matthew, Mark, Luke, Acts) agree on twelve names with one variation in the tenth to twelfth positions (Thaddaeus or Judas of James).
Where the text shows it: Mark 3:13-19 — Jesus appoints twelve and the list follows.Luke 6:12-16 — Chosen after a night of prayer and named apostles.Matthew 10:2-4 — The list as sent out on mission.Acts 1:13 — The list after the ascension, without Judas Iscariot. Sources: Matthew 10:2-4 · Mark 3:13-19 · Luke 6:12-16 · Acts 1:13
Judas Iscariot, son of Simon
FamilyStated in the textJohn twice names the father of Judas Iscariot as Simon. The other Gospels do not give his father.
Where the text shows it: John 6:71 — Judas the son of Simon Iscariot.John 13:26 — Jesus gives the morsel to Judas the son of Simon Iscariot. Sources: John 6:71 · John 13:26
Peter and Andrew are brothers
FamilyStated in the textMatthew calls Andrew the brother of Simon Peter, and John says Andrew found his brother Simon and brought him to Jesus. TIPNR records both as sons of a man called John.
Where the text shows it: Matthew 4:18 — Simon called Peter and Andrew his brother casting a net.John 1:40-42 — Andrew is "Simon Peter's brother" and brings Simon to Jesus.Mark 1:16 — Simon and Andrew, Simon's brother. Sources: Matthew 4:18 · John 1:40-42
Peter, son of John (or Jonah)
FamilyStated in the textJesus addresses Peter as "Simon son of John" in John's Gospel, and as "Simon Bar-Jonah" in Matthew; the two forms are usually understood as variants of one name. Andrew is thus also a son of this man.
Ways people read this (1)
- Some read "Jonah" as a separate name or as a nickname; most take it as a form of Johanan.
Sources: John 1:42 · Matthew 16:17
Peter and Andrew fished alongside James and John
WorkStated in the textLuke calls James and John "partners" of Simon in the fishing trade, and Mark shows the two sets of brothers called at the same shore, one pair mending nets and the other casting them, with Zebedee's hired men present.
Where the text shows it: Luke 5:10 — James and John, sons of Zebedee, were partners with Simon.Luke 5:7 — The partners in the other boat are called to help.Mark 1:16-20 — Two pairs of brothers called in succession. Ways people read this (1)
- Luke says "partners" (koinonoi). The precise legal form of the business is not stated.
Sources: Luke 5:1-11 · Mark 1:16-20
Two pairs of brothers among the Twelve
RoleStated in the textFour of the Twelve are two sets of brothers, named together in the lists and called in adjacent scenes: Simon Peter and Andrew, James and John.
Where the text shows it: Matthew 4:18-22 — Both calls told back to back.Mark 3:16-18 — The four appear consecutively in the list.Mark 13:3 — Peter, James, John and Andrew ask Jesus privately. Sources: Matthew 4:18-22 · Mark 3:16-18
James and John are brothers, sons of Zebedee
FamilyStated in the textMatthew says James son of Zebedee and John his brother were in the boat with their father Zebedee.
Where the text shows it: Matthew 4:21 — James the son of Zebedee and John his brother with Zebedee.Mark 3:17 — James the son of Zebedee and John the brother of James.John 21:2 — The sons of Zebedee among the disciples. Sources: Matthew 4:21 · Mark 3:17
Sons of Thunder
RoleStated in the textJesus gave James and John the surname Boanerges, which Mark glosses as "sons of thunder"; Luke shows them asking to call fire down on a Samaritan village.
Where the text shows it: Mark 3:17 — Jesus surnames them Boanerges.Luke 9:54 — They ask about calling down fire. Sources: Mark 3:17 · Luke 9:54
The inner circle: Peter, James, John
RoleStated in the textOn three occasions Jesus takes only Peter, James and John: the raising of Jairus' daughter, the transfiguration, and Gethsemane.
Where the text shows it: Mark 5:37 — Only Peter, James and John allowed to follow.Mark 9:2 — Taken up the mountain.Mark 14:33 — Taken deeper into Gethsemane. Sources: Mark 5:37 · Mark 9:2 · Mark 14:33
Andrew first followed John the Baptist
Teacher & studentStated in the textJohn's Gospel says two disciples of John the Baptist followed Jesus after he was pointed out; one is Andrew. The other is unnamed.
Where the text shows it: John 1:35-40 — Two of John's disciples follow Jesus; one is Andrew.John 1:41-42 — Andrew then finds Simon. Sources: John 1:35-42
The unnamed companion of Andrew in John 1
FriendsDebatedJohn 1:35-40 leaves one of the two early disciples unnamed. Some readers propose John son of Zebedee, based on the Gospel's habit of not naming its own author and the reticence about the "other disciple".
Where the text shows it: John 1:35-40 — Andrew and an unnamed disciple.John 21:24 — The Gospel's author is identified only as "this disciple". Ways people read this (2)
- Proposal: the writer modestly omits his own name (John son of Zebedee).
- Others note that the text never says so and that the unnamed disciple may only be a literary device or another person.
Sources: John 1:35-40
Philip, Andrew and Peter from Bethsaida
HometownStated in the textJohn says Philip was from Bethsaida, the city of Andrew and Peter. Peter and Andrew later have a house in Capernaum.
Where the text shows it: John 1:44 — Philip from Bethsaida, the city of Andrew and Peter.John 12:21 — Philip of Bethsaida in Galilee.Mark 1:29 — Simon and Andrew's house in Capernaum. Sources: John 1:44 · John 12:21
Philip and Andrew act together
FriendsStated in the textJohn shows Philip and Andrew paired in two scenes: the feeding of the five thousand and the Greeks who ask to see Jesus. Both are from Bethsaida.
Where the text shows it: John 6:5-8 — Jesus asks Philip; Andrew offers the boy's loaves.John 12:21-22 — Philip tells Andrew, and they tell Jesus. Sources: John 6:5-8 · John 12:21-22
Philip brings Nathanael to Jesus
FriendsStated in the textAfter being called, Philip finds Nathanael and invites him to come and see Jesus. John does not use the word "friend" but shows the two in easy acquaintance.
Where the text shows it: John 1:45-46 — Philip finds Nathanael and says "Come and see".John 21:2 — Nathanael of Cana in Galilee is among those later with Peter and Thomas. Ways people read this (1)
- The claim of close friendship is an inference from the scene.
Sources: John 1:43-51
Nathanael is usually identified with Bartholomew
RoleWidely acceptedJohn never lists Bartholomew and the Synoptics never mention Nathanael. The identification rests on Philip being paired with Bartholomew in the lists and Nathanael being Philip's acquaintance.
Where the text shows it: Matthew 10:3 — Philip and Bartholomew paired.John 1:45 — Philip and Nathanael paired.John 21:2 — Nathanael named among the disciples. Ways people read this (2)
- Bartholomew (Bar-Talmai) may be a patronymic with a personal name such as Nathanael.
- The identification is an inference; no text states it.
Sources: Matthew 10:3 · John 1:45
Nathanael from Cana in Galilee
HometownStated in the textJohn says Nathanael was from Cana in Galilee. He first expressed doubt that anything good could come from Nazareth.
Where the text shows it: John 21:2 — Nathanael of Cana in Galilee.John 1:46 — "Can anything good come out of Nazareth?" Sources: John 21:2 · John 1:46
Levi and Matthew the tax collector
RoleWidely acceptedThe tax collector called in Mark and Luke is named Levi; Matthew's Gospel tells the same story with the name Matthew, and Matthew is an apostle while Levi is not in the lists. The two are widely taken as one man with two names.
Ways people read this (1)
- No text says "Levi, also called Matthew".
Sources: Matthew 9:9 · Mark 2:14 · Luke 5:27
Matthew the tax collector at Capernaum
WorkWidely acceptedMatthew's call comes soon after Jesus returned to "his own city", generally understood to be Capernaum, and Mark sets Levi's booth near the seashore.
Where the text shows it: Matthew 9:1 — Jesus comes to his own city.Mark 2:13-14 — Beside the sea Jesus sees Levi at the tax booth. Sources: Matthew 9:1-9 · Mark 2:13-14
Where were James and John from?
HometownHypothesisNo Gospel text states the home town of James and John. Bethsaida has been proposed because their business partners were from there; Capernaum is also possible.
Where the text shows it: Luke 5:10 — Partners of Simon, who was from Bethsaida.Mark 1:19-21 — Called by the Sea of Galilee, then in Capernaum. Ways people read this (3)
- Bethsaida: via partnership with Peter and Andrew.
- Capernaum: they go straight to Capernaum after the call.
- The evidence shows association in trade and region, and nothing more specific.
Sources: Luke 5:10
The apostles as Galileans
HometownWidely acceptedThe apostles are addressed as "men of Galilee", and Peter was identified by his speech. Many of the individual apostles are placed in Galilee by the Gospels.
Where the text shows it: Acts 1:11 — Angels address the apostles as men of Galilee.Acts 2:7 — "Are not all these who are speaking Galileans?"Matthew 26:73 — Peter's accent gives him away. Ways people read this (1)
- Galilee is explicit for Peter, Andrew, Philip, Nathanael and Matthew by location; for Thomas, James of Alphaeus, Thaddaeus and Simon the Zealot no place is stated.
Sources: Acts 1:11 · Acts 2:7
Judas Iscariot: the only Judean?
HometownDebatedIscariot is often read as Hebrew "man of Kerioth", a place in Judah, which would make Judas the only apostle from Judea. The Gospels never explain the word.
Ways people read this (4)
- Ish-Kerioth: "man of Kerioth" in Judah, most widely held.
- Sicarius: from Latin for a dagger-man, implying a link with violent nationalists.
- Other derivations are proposed (Aramaic for "liar" or "deliverer"). Since Iscariot also stands after the father's name, it may be a family name.
- "Only non-Galilean" also assumes the origins of Thomas, Thaddaeus, James of Alphaeus and Simon the Zealot are Galilean, which is not stated.
Sources: John 6:71 · Joshua 15:25
Levi/Matthew is called son of Alphaeus
FamilyWidely acceptedMark calls Levi the tax collector "the son of Alphaeus", and TIPNR records Matthew as a son of Alphaeus. The Matthew and Luke lists do not give Matthew's father.
Where the text shows it: Mark 2:14 — Levi the son of Alphaeus.Mark 3:18 — Matthew in the list; father not given. Ways people read this (1)
- Depends on Levi = Matthew (see that relation).
Sources: Mark 2:14
James, son of Alphaeus
FamilyStated in the textThe lists call one apostle James the son of Alphaeus. Tradition calls him James the Less, from Mark's "James the small".
Sources: Mark 3:18 · Luke 6:15
Matthew and James as brothers (sons of Alphaeus)
FamilyDebatedMark gives the same father, Alphaeus, to Levi and to the apostle James. Some take the two as brothers, as TIPNR does. The text never says so, though it does name other sets of brothers explicitly.
Ways people read this (3)
- Brothers: one father name; Mark lists Matthew and James close together.
- Not brothers: Alphaeus was a common name; if brothers, the Gospels would probably say so as with Peter/Andrew and James/John; Matthew is paired with Thomas, not James, in Matthew's list.
- Jerome did not list Matthew among the Lord's brothers.
Sources: Mark 2:14 · Mark 3:18
Judas "of James" (Thaddaeus)
FamilyWidely acceptedLuke and Acts call an apostle "Judas of James" (Greek: Judas Iakobou), leaving open "son of" or "brother of". Matthew and Mark list Thaddaeus in that position, and the two are commonly taken as the same man.
Ways people read this (1)
- Judas-Thaddaeus harmonises the lists; the Gospels never say so.
Sources: Luke 6:16 · Mark 3:18
Judas as brother of James (Hieronymian reading)
FamilyDebatedJerome read "Judas of James" as "brother of James" and linked Judas to the author of Jude, who calls himself brother of James. Others read "son of James", and some distinguish the apostle from the letter writer.
Where the text shows it: Luke 6:16 — Judas of James.Jude 1 — Jude, brother of James.Jude 1:17 — The writer speaks of "the apostles" as a group he seems to stand apart from. Ways people read this (3)
- Brother: fits Jude 1 and Jerome's identification of James of Alphaeus with the Lord's brother.
- Son: the normal Greek genitive reading; the brother reading takes it as an ellipsis.
- Jude 17 has been taken to show the writer was not one of the Twelve.
Sources: Luke 6:16 · Jude 1 · Jerome, Against Helvidius (c. AD 383)
Simon the Zealot as a brother in the Alphaeus family
FamilyHypothesisThe claim that Simon the Zealot was a brother of James, Matthew and Judas is not supported by any text. It combines the Hieronymian list of four "brothers" (James, Joses, Simon, Jude) with the apostle list by shared names.
Ways people read this (3)
- For: James, Simon and Judas appear in both lists; Jerome made James and Judas apostles.
- Against: no text gives Simon the Zealot a father; "Simon" was extremely common; the name Joses is not in the apostle list.
- Some later traditions identify Simon the Zealot with the Symeon of Jerusalem; the ancient testimony is weak.
Sources: Luke 6:15 · Matthew 13:55
Four apostles as sons of Alphaeus
FamilyHypothesisThe proposal that James, Matthew, Judas and Simon the Zealot were all brothers and all cousins of Jesus combines several separate inferences. Each step is uncertain and only the first has support in the text (a shared father for James and Levi).
Ways people read this (3)
- Attested: James and Levi share a father named Alphaeus; Mary mother of James is at the cross.
- Inferred: Levi = Matthew; Alphaeus = Clopas; Judas is brother of James; Simon is also brother; Mary of Clopas is Mary's sister.
- Each inference has defenders, but the combined case depends on all of them at once.
Sources: Mark 2:14 · Luke 6:15-16
Thomas within the Alphaeus/Clopas family
FamilyHypothesisNo text links Thomas to the Alphaeus or Clopas branch. The idea rests on Thomas being called Didymus ("twin"), combined with lists where Thomas is placed near Matthew or James; it is an inference, not a report.
Ways people read this (3)
- Attested: Thomas is named Didymus; no sibling is named.
- Not attested: his father, his family, or his place of origin.
- The pairing in Matthew's list is of Thomas with Matthew, which could equally support friendship or a shared mission.
Sources: John 11:16 · John 20:24
Thomas "the twin"
FamilyHypothesisJohn twice glosses Thomas as Didymus, "the twin". Later Syriac tradition calls him Judas Thomas and some texts connect him with Jude the brother of Jesus; the Gospels do not name his twin.
Where the text shows it: John 11:16 — Thomas, called the Twin.John 21:2 — Thomas called the Twin. Ways people read this (2)
- Tradition: the name Judas Thomas appears in early Syriac writings.
- Caution: Thomas and Didymus are the Aramaic and Greek words for twin; a nickname, not a proof of kinship to any apostle.
Sources: John 11:16 · John 21:2
Pairings in the apostle lists
RoleDebatedMatthew's list arranges the Twelve in six apparent pairs, and Mark says Jesus sent them out two by two. Some see these as mission pairs; the texts do not say the list order gives partners.
Where the text shows it: Matthew 10:2-4 — Pairs joined by "and": Simon and Andrew, James and John, Philip and Bartholomew, Thomas and Matthew, James and Thaddaeus, Simon and Judas.Mark 6:7 — Sent out two by two. Ways people read this (3)
- For: mission pairs, with the brothers together.
- Against: Luke and Mark use different orders; the pairing is not stated.
- Relevant to family claims: it places Matthew with Thomas, not with James.
Sources: Matthew 10:2-4 · Mark 6:7
Is the Twelve one extended family network?
FriendsHypothesisOne proposal is that most of the Twelve were kin, neighbours or business contacts around the Sea of Galilee. The Gospels attest two brother pairs, a partnership, a shared home town for three and an invitation between two; the wider network is a pattern suggested by those links, not a stated fact.
Ways people read this (3)
- Attested: two sets of brothers, partners, a shared home town, one invitation.
- Inferred: kinship among Alphaeus's sons, Thomas, Simon, Judas.
- The Galilean setting makes local links likely but not proven for each apostle.
Sources: Luke 5:10 · John 1:44
Jesus calls Matthew the tax collector
Teacher & studentStated in the textThe Gospels agree that Jesus called a tax collector sitting at his booth with the simple words "Follow me", and that he then ate with tax collectors and sinners at his house.
Sources: Matthew 9:9 · Luke 5:27-32
Peter, James the Lord's brother, and John as pillars
RoleStated in the textPaul names James, Cephas and John as the "pillars" of the church in Jerusalem. In Galatians 1 he met Peter and saw also James the Lord's brother.
Sources: Galatians 1:18-19 · Galatians 2:9
