Luke the Evangelist (Λουκᾶς Loukas) was an Early Christian writer who the Church Fathers such as Jerome and Eusebius said was the author of the Gospel of Luke and the Acts of the Apostles.
The Roman Catholic Church venerates him as Saint Luke, patron saint of physicians, surgeons, students, butchers, and artists; his feast day is October 18.
Luke was a physician and lived in the Greek city of Antioch in Asia Minor.
His earliest notice is in Paul’s Epistle to Philemon, verse 24. He is also mentioned in Colossians 4:14 and 2 Timothy 4:11, two works commonly ascribed to Paul. The next earliest account of Luke is in the Anti-Marcionite Prologue to the Gospel of Luke, a document once thought to date to the 2nd century, but which has more recently been dated to the later 4th century. Helmut Koester, however, claims that the following part – the only part preserved in the original Greek – may have been composed in the late 2nd century:
“ | Luke, a native of Antioch, by profession a physician. He had become a disciple of the apostle Paul and later followed Paul until his [Paul’s] martyrdom. Having served the Lord continuously, unmarried and without children, filled with the Holy Spirit he died at the age of 84 years. | ” |
Epiphanius states that Luke was one of the Seventy (Panarion 51.11), and John Chrysostom indicates at one point that the “brother” Paul mentions in 2 Corinthians 8:18 is either Luke or Barnabas. J. Wenham asserts that Luke was “one of the Seventy, the Emmaus disciple, Lucius of Cyrene and Paul’s kinsman.” Not all scholars are as confident of all of these attributes as Wenham is, not least because Luke’s own statement at the beginning of the Gospel of Luke (Luke 1:1–4) freely admits that he was not an eyewitness to the events of the Gospel.
If accepted that Luke was in fact the author of the Gospel bearing his name and also the Acts of the Apostles, certain details of his personal life can be reasonably assumed. While he does exclude himself from those who were eyewitnesses to Jesus’ ministry, he repeatedly uses the word “we” in describing the Pauline missions in Acts of the Apostles, indicating that he was personally there at those times.
There is similar evidence that Luke resided in Troas, the province which included the ruins of ancient Troy, in that he writes in Acts in the third person about Paul and his travels until they get to Troas, where he switches to the first person plural. The “we” section of Acts continues until the group leaves Philippi, when his writing goes back to the third person. This change happens again when the group returns to Philippi. There are three “we sections” in Acts, all following this rule. Luke never stated, however, that he lived in Troas, and this is the only evidence that he did.
The composition of the writings, as well as the range of vocabulary used, indicate that the author was an educated man. The quote in the Letter of Paul to the Colossians differentiating between Luke and other colleagues “of the circumcision” Colossians 4:10 and 11, compared with 14, has caused many to speculate that this indicates Luke was a Gentile. If this were true, it would make Luke the only writer of the New Testament who can clearly be identified as not being Jewish. However, that is not the only possibility. The phrase could just as easily be used to differentiate between those Christians who strictly observed the rituals of Judaism and those who did not.
Luke died at age 84 in Boeotia, according to a “fairly early and widespread tradition”. According to Nikiphoros-Kallistos Xanthopoulos (Eccles. History XIVth c. AD., Migne P.G. 145, 876) and others, Luke’s Tomb was located in Thebes (Greece), from whence his relics were transferred to Constantinople in the year 357.
