The Gospel of Luke

Synopsis

Luke opens not with genealogy or a plunge into ministry but with a formal literary preface (1:1–4), addressed to "most excellent Theophilus," in which the author explains that he has investigated events "from the very first" in order to write "an orderly account." This preface, written in polished Greek reminiscent of Greco-Roman historiography, immediately signals that Luke intends something more self-consciously literary than the other Gospels. What follows is the most extensive birth narrative in the New Testament, telling the stories of both John the Baptist's and Jesus's births in parallel, and including three of the best-known canticles in Christian worship: Mary's Magnificat, Zechariah's Benedictus, and Simeon's Nunc Dimittis.

After a brief account of Jesus's baptism, temptation, and the start of his Galilean ministry, Luke includes a long, distinctive section often called the "travel narrative" (roughly 9:51–19:27), structured loosely around a journey toward Jerusalem and containing much of Luke's most famous unique material, including the parables of the Good Samaritan and the Prodigal Son. The Gospel closes with the crucifixion, resurrection, and the appearance on the road to Emmaus, ending with the disciples in Jerusalem awaiting the promised Spirit — a deliberate hand-off to the book of Acts, which Luke also wrote as a second volume continuing the same story into the early church.

Historical Background

Tradition identifies the author as Luke, described in Colossians 4:14 as "the beloved physician" and understood to be a travel companion of Paul, based partly on several first-person "we" passages in Acts (for example, Acts 16:10–17) where the narrator appears to describe himself as present. Luke is never named as the author within the Gospel or Acts themselves; the attribution comes from early church tradition, again traceable to sources like Irenaeus in the late second century. Most scholars accept that the same author wrote both Luke and Acts, given the shared address to Theophilus, consistent vocabulary and style, and the deliberate way Luke's ending sets up Acts's beginning, though whether that author was in fact the historical Luke, physician and companion of Paul, is treated with more caution by some scholars than by others.

Most mainstream scholarship dates Luke to roughly AD 80 to 90, consistent with the Two-Source Hypothesis's assumption that Luke used Mark as one of his sources. A significant minority, including a number of more conservative scholars, argue for an earlier date, sometimes before AD 70, pointing partly to the fact that Acts ends abruptly with Paul under house arrest in Rome, before his death, and without narrating the fall of Jerusalem — a silence some read as evidence Acts (and therefore Luke) was completed before those events occurred, though others regard the ending as a deliberate literary choice rather than a dating clue. Luke's Gospel and Acts are addressed to a clearly non-Jewish audience concerned with how the Christian movement relates to the wider Roman world, and the Gospel shows particular attentiveness to Gentiles, Samaritans, the poor, and women in ways that go well beyond the other Synoptics.

Scholarly Discussions and Open Questions

Sources: Mark, Q, and "L"

Like Matthew, Luke is understood under the Two-Source Hypothesis to have used Mark and the hypothetical sayings source Q. Luke also contains a large body of material found nowhere else in the New Testament — the birth narratives, the travel narrative's unique parables, and more — conventionally labeled "L." As with Matthew's "M," scholars debate whether "L" reflects a single written source, oral tradition Luke gathered himself, or material he composed, consistent with his own claim to have "investigated" the story "from the very first."

The Census of Quirinius

Luke dates Jesus's birth to a census "when Cyrenius [Quirinius] was governor of Syria" (2:1–2), which the Jewish historian Josephus places around AD 6, roughly a decade after the death of Herod the Great, under whose reign Matthew places Jesus's birth. This apparent tension has been discussed by scholars for well over a century, with proposed solutions ranging from an earlier, otherwise unattested Quirinius census, to translation questions about the Greek text, to the possibility that Luke's chronology is simply in tension with Matthew's. No solution commands universal agreement, and the question remains one of the more debated points of New Testament chronology.

Luke as Historian

Because Luke explicitly frames his work as a historical investigation, scholars have paid close attention to how it compares with ancient historiographical conventions, including the composition of speeches, a common and accepted practice among ancient historians that raises questions for modern readers about how literally to take the speeches attributed to Jesus and others. Assessments vary considerably, from scholars who treat Luke as a careful and reasonably reliable ancient historian to those who treat "orderly account" primarily as a literary and theological framing device rather than a claim to modern standards of historical precision.

Key Themes

Universal salvation. Luke repeatedly emphasizes that the good news extends beyond Israel to Samaritans and Gentiles, tracing Jesus's genealogy back to Adam rather than stopping at Abraham, as Matthew does.

Concern for the poor and marginalized. Luke's Beatitudes pronounce blessing on "the poor" without Matthew's qualifier "in spirit," and pair them with corresponding woes to the rich (6:20–26); parables like the Rich Man and Lazarus and Lazarus's own place in the narrative reflect a sustained concern with poverty and reversal.

Women. Luke gives women a more prominent narrative role than the other Gospels, from Mary and Elizabeth in the birth narrative to Mary Magdalene, Joanna, and Susanna as named supporters of Jesus's ministry (8:1–3).

Prayer and the Spirit. Jesus prays more often in Luke than in any other Gospel, and the Spirit's activity, foreshadowed throughout, sets up its central role once the narrative continues into Acts.

Joy. From the angelic announcements of the birth narrative to the disciples' response at the ascension, Luke frames the story with recurring notes of joy and praise.

Reversal. Mary's Magnificat sets the tone early — "he hath put down the mighty from their seats, and exalted them of low degree" (1:52) — and the theme recurs throughout, in parables like the Pharisee and the tax collector and in Jesus's repeated statement that "the last shall be first, and the first last."
