Who Was the Apostle Luke in the New Testament
Who Was the Apostle Luke in the New Testament
Luke was a Gentile physician who became a companion of the apostle Paul and the author of both the Gospel of Luke and the Acts of the Apostles [2]. His name appears three times in the New Testament epistles—Colossians 4:14, 2 Timothy 4:11, and Philemon 24—where Paul identifies him as "the beloved physician" [1, 5]. These brief references, combined with early Christian tradition, provide the primary evidence for reconstructing his identity and role in the early church.
Origins and Background
According to well-established tradition, Luke was born in Antioch, Syria, where he received training in medicine [1, 5]. This Syrian origin is attested by early Christian writers including Jerome, who specifically called Luke "the physician of Antioch" [5]. His Gentile background is confirmed by Paul's letter to the Colossians, where Luke is mentioned separately from those identified as "of the circumcision"—that is, Jewish believers [7]. This makes Luke unique among the New Testament writers, as he appears to be the only Gentile author of canonical Scripture.
The circumstances and date of Luke's conversion remain unknown [2]. Some traditions claim he was one of the seventy disciples sent out by Jesus during his earthly ministry, but this appears unlikely given Luke's own statement in his Gospel that he was not "an eye-witness and minister of the word from the beginning" [2, 6]. More probably, Luke encountered Paul during the apostle's missionary journeys and was converted through that contact [2, 5].
Companion of Paul
The most detailed evidence for Luke's activities comes from the "we" passages in Acts, where the narrative shifts from third-person to first-person plural, indicating the author's presence with Paul. Luke likely joined Paul at Troas, where he may have practiced medicine before his conversion [2]. He accompanied Paul to Philippi but did not share Paul's imprisonment there, nor did he continue with the apostle when Paul departed after his release [2]. The narrative suggests Luke remained in Philippi for several years.
Luke rejoined Paul during the apostle's third visit to Philippi, as indicated in Acts 20:5-6 [2]. From this point, he appears to have been Paul's consistent companion through the journey to Jerusalem, the subsequent imprisonment in Caesarea, the voyage to Rome (including the shipwreck at Malta), and Paul's Roman captivity. Paul's reference to Luke in 2 Timothy 4:11—"Only Luke is with me"—suggests Luke remained faithful even when other companions had departed, making him one of Paul's most steadfast associates [1].
The Gospel and Acts
The Gospel of Luke is attributed to this same physician by "the general consent of ancient Christendom" [3]. Internal evidence supports this attribution: the author demonstrates detailed knowledge of Paul's ministry (as shown in Acts), uses medical terminology with precision, and writes in polished Greek suitable for a well-educated Gentile audience. The Gospel's preface (Luke 1:1-4) indicates the author carefully investigated eyewitness accounts and earlier written sources before composing his orderly narrative [6].
The dating of Luke's Gospel remains debated, though it clearly preceded Acts, which refers to "the former treatise" [3]. If Luke wrote during Paul's imprisonment at Caesarea, the Gospel would date to approximately AD 58-60 [3]. This would place its composition during a period when Luke had direct access to Paul and potentially to other eyewitnesses in the region, including members of the Jerusalem church.
Luke's stated purpose was to provide Theophilus—and by extension, other readers—with certainty concerning the things they had been taught [6]. His Gospel emphasizes Jesus's concern for the marginalized, including Gentiles, women, and the poor, themes that may reflect Luke's own perspective as a Gentile convert and his observations of Paul's ministry to diverse populations.
Historical Questions and Scholarly Debate
The identification of Luke the physician with Luke the evangelist, while traditional, rests primarily on the convergence of early church testimony with the internal evidence of Luke-Acts. No ancient source questions this identification, and the medical language in both works supports the tradition that their author was trained in medicine [5].
Some have attempted to identify Luke with Lucius of Cyrene, mentioned in Acts 13:1 as a prophet and teacher at Antioch, or with Lucius mentioned in Romans 16:21 as Paul's kinsman [4, 8]. However, Luke and Lucius are distinct names—Luke being an abbreviated form of Lucanus, while Lucius is a separate Roman name [1]. Adam Clarke suggested that the Lucius in Romans might be "Luke the evangelist," but this identification lacks strong support and conflicts with Paul's description of Lucius as a kinsman, which would imply Jewish descent [8].
The tradition that Luke was ordained bishop of Cenchreae appears to confuse him with Lucius mentioned in Romans 16:21 [4]. Such later traditions often conflated figures with similar names or attempted to provide apostolic succession for various churches.
Legacy in Early Christianity
Luke's contribution to the New Testament is substantial: his two-volume work comprises roughly one-quarter of the New Testament by word count. His careful historical method, attention to chronological and geographical detail, and concern for accurate reporting established a model for Christian historiography. The Acts of the Apostles provides the only canonical account of the early church's expansion from Jerusalem to Rome, preserving invaluable information about Paul's ministry and the challenges facing the first generation of believers.
Paul's affectionate description of Luke as "the beloved physician" suggests not only professional respect but genuine friendship [5]. In an era when medical knowledge was limited and travel dangerous, Luke's skills would have been invaluable to Paul, who suffered various physical ailments and endured repeated beatings, stonings, and other hardships. Yet Luke's loyalty appears to have transcended professional utility—he remained with Paul when others had abandoned him, demonstrating the depth of commitment that characterized the closest relationships in the early Christian movement.
