Luke, the Evangelist
Who Was Luke?
Luke is mentioned by name only three times in the New Testament, all in Paul's letters. Paul calls him "Luke the beloved physician" (Colossians 4:14), includes him among his fellow workers (Philemon 1:24), and during his final imprisonment notes that "Luke alone is with me" (2 Timothy 4:11). This last reference reveals Luke's loyalty — when others had departed, Luke remained.
From Colossians 4:10-14, we learn that Luke was a Gentile. Paul distinguishes between his Jewish co-workers (Aristarchus, Mark, and Jesus called Justus, who are "of the circumcision") and another group that includes Epaphras, Luke, and Demas. Luke was thus one of the few non-Jewish authors of Scripture — possibly the only one. His Gentile background uniquely positioned him to write a Gospel that emphasizes God's grace extending to all peoples.
Early church tradition associated Luke with Antioch in Syria, and he clearly shows a special interest in that city's role in the spread of Christianity (Acts 11:19-27; 13:1; 14:26; 15:22-35). His profession as a physician is reflected in his occasionally more precise descriptions of medical conditions in both his Gospel and Acts.
The "We" Passages in Acts
Luke never names himself in either his Gospel or Acts, but his presence with Paul is revealed through the famous "we" passages in Acts, where the narrative shifts from third person to first person plural. These sections indicate the periods when Luke personally accompanied Paul:
The first "we" section begins at Troas during Paul's second missionary journey (Acts 16:10-17), covering the crossing to Macedonia and arrival at Philippi. Luke apparently remained at Philippi for several years, because the next "we" passage does not resume until Paul returns to Philippi during his third journey (Acts 20:5-15). Luke then accompanied Paul on the voyage to Jerusalem (Acts 21:1-18) and, after Paul's arrest and imprisonment, on the dramatic sea voyage to Rome (Acts 27:1-28:16).
These passages provide some of the most vivid narrative in the New Testament, particularly the account of the shipwreck on the way to Rome, which reads like a firsthand eyewitness report because it is one.
Luke's Gospel: A Careful Investigation
Luke's Gospel opens with a formal literary preface addressed to "most excellent Theophilus," explaining his purpose: "It seemed good to me also, having followed all things closely for some time past, to write an orderly account for you, most excellent Theophilus, that you may have certainty concerning the things you have been taught" (Luke 1:1-4).
This introduction reveals Luke as a researcher and historian. He acknowledges earlier written accounts of Jesus' life, notes that he relied on eyewitness testimony, and states his goal of providing an orderly, reliable narrative. His Gospel is the longest book in the New Testament and contains more unique material than any other Gospel.
Among the material found only in Luke are the detailed birth narratives of John the Baptist and Jesus (Luke 1-2), including Mary's Magnificat (Luke 1:46-55) and Zechariah's Benedictus (Luke 1:67-79). The parables of the Good Samaritan (Luke 10:25-37), the Prodigal Son (Luke 15:11-32), the Rich Man and Lazarus (Luke 16:19-31), and the Pharisee and the Tax Collector (Luke 18:9-14) appear only in Luke's Gospel. The account of the walk to Emmaus (Luke 24:13-35) and Jesus' words to the thief on the cross (Luke 23:42-43) are also unique to Luke.
Distinctive Themes
Luke's writings emphasize several themes that reflect his theological perspective and pastoral concern.
Universal salvation. More than any other Gospel writer, Luke stresses that the gospel is for all people — Jews and Gentiles, men and women, rich and poor. Simeon's prophecy calls the infant Jesus "a light for revelation to the Gentiles" (Luke 2:32). Jesus' genealogy in Luke traces back not just to Abraham (as in Matthew) but to Adam, emphasizing His connection to all humanity (Luke 3:38).
Concern for the marginalized. Luke highlights Jesus' compassion for the poor, the sick, women, Samaritans, tax collectors, and sinners. Women play a more prominent role in Luke than in any other Gospel: Mary, Elizabeth, Anna, the widow of Nain, the sinful woman who anointed Jesus, Mary and Martha, and the women at the tomb.
Prayer. Luke records more of Jesus' prayers than any other Gospel writer. Jesus prays at His baptism (Luke 3:21), before choosing the twelve (Luke 6:12), at the Transfiguration (Luke 9:28-29), and in Gethsemane with intensified detail (Luke 22:41-44).
The Holy Spirit. Both the Gospel and Acts give prominent attention to the work of the Holy Spirit. The Spirit's role in Jesus' conception, baptism, and ministry (Luke 1:35; 3:22; 4:1, 14, 18) prepares for the dramatic outpouring at Pentecost (Acts 2:1-4) and the Spirit's ongoing guidance throughout Acts.
Luke as Historian
Luke's accuracy as a historian has been repeatedly confirmed by archaeological and historical research. His use of correct titles for Roman officials — proconsul for Sergius Paulus in Cyprus (Acts 13:7), politarchs for the magistrates of Thessalonica (Acts 17:6), and Asiarchs for officials in Ephesus (Acts 19:31) — demonstrates careful attention to detail. His dating of events by reference to Roman rulers (Luke 2:1-2; 3:1-2) anchors the gospel narrative in verifiable history.
The Gallio inscription from Delphi confirms Luke's reference to Gallio as proconsul of Achaia (Acts 18:12), providing one of the most important chronological anchors for New Testament chronology. Luke's detailed description of the voyage to Rome (Acts 27) has been called one of the most accurate accounts of ancient seamanship in surviving literature.
Biblical Context
Luke is named in Colossians 4:14, 2 Timothy 4:11, and Philemon 1:24. His authorship of the Third Gospel and Acts is indicated by the prefaces addressed to Theophilus (Luke 1:1-4; Acts 1:1). The 'we' passages in Acts (16:10-17; 20:5-15; 21:1-18; 27:1-28:16) reveal his travels with Paul. His Gospel contains unique material including the infancy narratives (Luke 1-2), major parables (Luke 10, 15, 16, 18), and post-resurrection appearances (Luke 24).
Theological Significance
Luke's contribution to the New Testament is theologically significant for its emphasis on the universality of salvation, the role of the Holy Spirit, and the continuity between Israel's story and the church's mission. His two-volume work traces a single narrative arc from the announcement of John the Baptist's birth to Paul's preaching in Rome, demonstrating that the gospel's expansion from Jerusalem to the ends of the earth was God's plan from the beginning. Luke's careful historical method also establishes the principle that Christian faith is grounded in real events, not myth.
Historical Background
Early church tradition unanimously identified Luke as the author of the Third Gospel and Acts. The Muratorian Fragment (late 2nd century), the Anti-Marcionite Prologue, Irenaeus, Clement of Alexandria, and Tertullian all affirm Lukan authorship. Jerome described Luke as a physician from Antioch. Some traditions say Luke was a painter, and numerous icons are attributed to him, though this tradition is late and legendary. Luke's Greek style is the most polished in the New Testament, and his literary skill is evident in the way he adapts his style to different contexts — writing Septuagintal Greek in the infancy narratives and more colloquial Greek in the travel sections of Acts.
