Luke 3:35-38 Commentary: Jesus' Lineage from Serug to the Son of God

Genealogies in the first-century world did more than record family trees. For Jews, they established tribal identity, priestly legitimacy, and messianic claims. For Romans and Greeks, they could demonstrate noble ancestry or divine descent. Luke places Jesus' genealogy immediately after his baptism and the heavenly declaration “You are my beloved Son” (3:22), anchoring that identity in history.

Unlike Matthew, who moves forward from Abraham, Luke works backward from Jesus to Adam and then to God. This reverse direction emphasizes the universal scope of Jesus' mission. The names from Serug to Shelah come from the period after the scattering at Babel (Gen 10, 11). Peleg's name means “division,” linked to the dividing of the earth (Gen 10:25). Reu, Serug, and Nahor (in v.34) were ancestors of Abraham who lived in the region of Ur and Haran. By including them, Luke ties Jesus to the nations that spread from Babel, not only to Israel.

The genealogy also bridges the flood. Noah and his sons Shem, Ham, and Japheth repopulated the earth. Shem is singled out here, continuing the line that would lead to Abraham. Then the antediluvian patriarchs, Lamech, Methuselah, Enoch, Jared, Mahalaleel, Cainan, Enosh, Seth, trace back to Adam. This sweep from creation to Christ tells one continuous story. Luke wants his readers, many of them non-Jews, to see that Jesus belongs to every people, every era, and ultimately to God himself.

The most notable textual issue in these verses is the name Cainan in verse 36. While the Hebrew text of Genesis 10:24 and 11:12 lists Arphaxad as the father of Shelah, the Greek Septuagint inserts a Cainan between them. Luke follows the Septuagint reading. Gill notes that early Greek manuscripts of Luke (including Beza's) omitted this Cainan, suggesting a scribal addition. Adam Clarke mentions the possibility that Cainan was a surname of Shelah. The consulted sources thus flag a real textual variant, but do not question the theological coherence of the genealogy. Most modern editions of the Greek New Testament include Cainan, though some note its uncertain attestation. No other significant variants are reported for these verses.

Early church fathers such as Irenaeus and Tertullian used Luke's genealogy to defend Jesus' genuine humanity against Gnostic teachers who claimed his body was only an illusion. The connection to Adam reinforced the doctrine of recapitulation: Christ as the second Adam restores what the first Adam lost. In medieval liturgy, the genealogy was read at Christmas, reminding congregations that the Word indeed became flesh. During the Reformation, both Catholic and Protestant commentators treated the genealogy as historically reliable, though they noted the Cainan variation. Modern scholars often approach the genealogy as a theological composition, while conservative interpreters maintain its historical character. Across all eras, the phrase “son of God” at the end has been treasured as a bridge between the human Jesus and his divine identity.

Three-point outline

1. God works through ordinary generations. The names between Serug and Shelah are obscure, they appear nowhere else in the New Testament. Yet each one was a link in the chain that brought the Savior into the world. God does not need famous people; he uses fathers and mothers, grandparents, and ancestors whose names only he remembers.
2. Jesus is not a stranger to our humanity. The genealogy goes back to Adam, showing that Jesus shared the same flesh and blood as every person who has ever lived. He did not come as a distant deity but as a genuine human being, born into a specific family line that includes farmers, exiles, and sinners.
3. Jesus is also uniquely the Son of God. The final phrase “the son of Adam, the son of God” (v.38, my paraphrase) sets Jesus apart. Adam was God's son by creation; Jesus is God's Son by eternal relationship. This genealogy does not reduce Jesus to a product of history but affirms that he entered history from outside it.

Five-point outline

1. The genealogy confirms Jesus as the promised seed of Abraham and the descendant of David (the earlier part of Luke 3).
2. The names from Serug to Shelah show that God preserved a remnant through the scattering of nations after Babel.
3. The inclusion of Cainan (with its textual questions) reminds us that the Gospels are not modern historical documents, they are ancient testimonies with their own textual history, yet they reliably point us to Christ.
4. The patriarchs after the flood (Shem, Noah) and before the flood (Enoch, Methuselah) demonstrate that God's plan of redemption predates Abraham, it began at the fall.
5. Adam's title “son of God” (Wesley: “Adam received immediately from God, except sin and misery”) prepares us for Jesus, the true Son of God who comes to undo the damage of Adam's sin.

Illustration hooks

• A family photo album. Most people have relatives they have never met, great-grandparents from a century ago whose names are lost. But in God's story, every name matters. This genealogy is like God's own photo album, showing that Jesus has a real family history.
• A legal inheritance. In some cultures, proving descent from a particular ancestor is necessary to claim an inheritance. Jesus' genealogy proves that he is the rightful heir to the promises made to Abraham and to David, and also the heir of Adam's dominion (restored through his work).
• Bridge between two worlds. A bridge connects one side to another. This genealogy bridges the Old Testament and the New, connecting the creation of Adam to the ministry of Christ. It reassures us that the God who acted in Genesis is the same God who acts in the Gospels.

Questions your congregation is asking

• Why does Luke include so many names nobody can pronounce? Genealogies feel tedious, but they prove Jesus is a real person in real history. It answers the charge that Christianity is a myth.
• Does it matter that there is a Cainan in Luke but not in Genesis? Some people may worry about contradictions. The textual evidence suggests either a variant or an alternate name (Clarke). This is a copyist difference, not a contradiction in the original message.
• What does “son of God” mean for Adam? If Adam is God's son, then all humans are God's offspring in a sense. But Jesus is God's Son in a unique way, he is the one who restores what Adam lost.

This section of Luke's genealogy moves from the post-flood patriarchs all the way back to Adam and God. As you study together, ask yourselves: Why did Luke include these names? What does this tell us about Jesus, and about ourselves?

Discussion questions

1. Read Luke 3:35, 38 slowly. What names stand out to you? Are any familiar from the Old Testament?
2. Why do you think Luke traces Jesus' line backward to Adam, instead of stopping at Abraham like Matthew does? What does this suggest about Luke's audience?
3. The name Peleg means “division,” connected to the scattering of nations in Genesis 10:25. How does that ancient event still matter in the story of Jesus?
4. This genealogy includes both well-known figures (Noah, Adam) and obscure ones (Serug, Reu). What does this say about how God works through history?
5. Verse 38 calls Adam “the son of God.” In what sense is Adam God's son, and how is Jesus' Sonship different? (See also Luke 1:35; 3:22).
6. Some manuscripts include an extra Cainan in verse 36 that does not appear in the Hebrew Old Testament. Does this raise questions for you about the Bible's reliability? How might you respond?
7. How does knowing that Jesus shares a common ancestor with every person on earth affect the way you think about your neighbors, your community, or people of other nations?
