Person

Luke the Evangelist

A Gentile physician, historian, and traveling companion of the apostle Paul, traditionally the author of the third Gospel and the Acts of the Apostles. Together Luke and Acts comprise roughly one-quarter of the New Testament, making Luke the most prolific contributor by volume and (on the standard view) the only Gentile author in the canon. Paul calls him "the beloved physician" (Colossians 4:14, NASB95) and lists him among his fellow workers (Philemon 24); near the end of Paul's life, when others had departed, Paul writes "Only Luke is with me" (2 Timothy 4:11).

Biographical sketch

Background. Almost certainly a Gentile, Colossians 4:10-14 distinguishes Paul's coworkers "of the circumcision" (Aristarchus, Mark, Justus) from those that follow (Epaphras, Luke, Demas), placing Luke among the Gentile coworkers. Patristic tradition (Eusebius, Eccl. Hist. 3.4.6; the Anti-Marcionite Prologue to Luke) identifies him as a native of Antioch in Syria, which fits the unusual detail Luke gives Antioch in Acts (Acts 11:19-26; 13:1).
Profession. Trained as a physician (iatros, Col 4:14). Some scholars (W. K. Hobart in the 19th century, qualified by H. J. Cadbury later) argue that Luke's vocabulary betrays medical interest, terms for diseases, anatomical precision in the healing narratives, though Cadbury showed the same vocabulary was available to any educated Hellenistic writer. The vocational identification rests on Paul's testimony, not on diagnostic word-counts.
Conversion. Scripture is silent. Tradition does not place him among Jesus's earthly disciples (Luke 1:2 implicitly distinguishes himself from "those who from the beginning were eyewitnesses"). His conversion likely occurred at Antioch under early Hellenist preaching.
Travels with Paul. Luke joins Paul's missionary work at Troas on the second journey, marked by the abrupt shift from third-person to first-person plural in Acts 16:10 (the first of the "we passages"). The we-passages (Acts 16:10-17; 20:5-21:18; 27:1-28:16) trace Luke's personal participation: from Troas to Philippi on the second journey; from Philippi back to Jerusalem on the third journey; from Caesarea to Rome with Paul as prisoner; and through the shipwreck at Malta into Paul's first Roman imprisonment.
Faithful to the end. "Only Luke is with me" (2 Tim 4:11), written from Paul's final imprisonment under Nero, when Demas had deserted and others had been dispatched on missions. Luke was the last companion remaining.
Later tradition. Reports vary, Eusebius and Jerome say he died unmarried at age 84 in Boeotia (Greece); other traditions report martyrdom in Greece. Early evidence is thin.

Authorship contribution

The Gospel of Luke, third Gospel, dated AD 60-65 (conservative; before Acts) or AD 80-85 (most critical scholarship).
The Acts of the Apostles, the second volume of a unified two-volume work, dated AD 62-65 (conservative; the abrupt ending with Paul still under house arrest in Rome strongly suggests composition before Paul's execution) or AD 80-90 (critical).
Internal authorship case. Both volumes are addressed to the same patron Theophilus (Luke 1:3; Acts 1:1) and refer to a "first account" (Acts 1:1), the literary unity is uncontested. The we-passages constrain authorship to a Pauline traveling companion present at Troas, Philippi, Jerusalem, and Rome at specific times, a list that filters down to a small number of candidates. Of those, Luke alone is consistently named in Pauline lists from each relevant period (Col 4:14; Phlm 24; 2 Tim 4:11).
Patristic confirmation. The Muratorian Fragment (~AD 170-200), Irenaeus (Adv. Haer. 3.1.1), Clement of Alexandria, Tertullian, and the Anti-Marcionite Prologue all attribute the third Gospel and Acts to Luke. The unbroken tradition has no rival candidate.
Method. Luke opens the Gospel with the most explicit historiographical preface in the New Testament: "Inasmuch as many have undertaken to compile an account of the things accomplished among us, just as they were handed down to us by those who from the beginning were eyewitnesses and servants of the word, it seemed fitting for me as well, having investigated everything carefully from the beginning, to write it out for you in consecutive order, most excellent Theophilus" (Luke 1:1-3, NASB95). He claims to have done research, consulted eyewitnesses, and worked from prior written accounts, the methodology of a Hellenistic historian.

Theological themes

Salvation history. Luke structures his two volumes as one continuous narrative, Israel's promise → Jesus's life → the church's expansion from Jerusalem to Rome, situating the Christ-event as the climax of God's historical purpose.
Universalism / inclusion. Luke gives unique attention to the marginal, women (Mary's Magnificat, the widow of Nain, Mary and Martha, the women at the tomb), the poor (the Beatitudes in Luke 6 are sharper-edged on wealth than Matthew's), Samaritans (Good Samaritan, the grateful Samaritan leper), tax collectors and sinners (Zacchaeus, the prodigal son), and Gentiles (extended in Acts).
The Holy Spirit. Luke-Acts highlights the Spirit at every transition, Mary's conception, Jesus's baptism, the Spirit-driven mission in the wilderness, Pentecost, the Spirit-orchestrated outreach to Cornelius, the Spirit's restraining and directing of missionary travel.
Prayer. Luke records more of Jesus's prayer life than the other Synoptics and gives extensive parables on prayer (the persistent widow, the Pharisee and tax collector).
Historiographical accuracy. Luke's accuracy on political titles (proconsul, politarchēs of Thessalonica in Acts 17:6, Asiarchs of Ephesus in 19:31), geography, and travel detail has been repeatedly vindicated by archaeology, most famously by William Ramsay, who began as a critic and concluded that Luke was "a historian of the first rank."

Connection to codex concepts (added 2026-04-28 bulk extraction)

NT Authorship and Eyewitness Apologetics, Luke as Pauline companion and physician; the Luke 1.1-4 prologue is showcased as the New Testament's most explicit historiographical self-attestation grounding the Gospel in eyewitness research
Biblical Archaeology, Luke's politarch title for Thessalonian magistrates (Acts 17.6), once dismissed as anachronistic, vindicated by 1st-c. Macedonian inscriptions; emblematic of Ramsay's "historian of the first rank" verdict
Petrine Source Hypothesis, Luke named in the Two-Document Hypothesis (Mark + Q as sources for Matthew and Luke); Lukan dependence on Mark places his Gospel in the same Petrine chain of custody
