The preface makes clear that the writer was not an eyewitness of the things he recorded. Both the Gospel of Luke and Acts reveal that the author was a man of culture who had researched the information he needed for his writing but who was not one of the original followers of Jesus. An objection to Lukan authorship is that the theology, especially of Acts, has different emphases from that of Paul. But there is no reason why Luke should simply repeat what Paul said. Nor is it likely that Luke was one of Paul's converts. The writer does not contradict Paul, even though he does not quote him.
Nothing is known of Luke other than what we can glean from his two books and from the scant references to him in Paul's letters (Col. 4:14; 2 Tim. 4:11; Philemon 1:24). There is a tradition that he came from Antioch, and Colossians 4:14 indicates that he was a physician. Lukan authorship has sometimes been defended by noting medical language in Luke and Acts, but it has been shown that medical men in New Testament times used the ordinary language of laypeople and did not have a technical language of their own. There is nothing inconsistent with the tradition, however, and the author certainly shows an interest in the sick.
At the same time, Luke did not neglect the personal and human side of Jesus' life. Luke concerned himself with many people who would have been neglected by most writers of his day: children, women and poor people. Although many regarded these people as insignificant, Luke demonstrated Jesus' special concern for them.
Luke was clearly a cultured individual who was able to write in a variety of styles. His opening paragraph resembles older, sophisticated Greek, but at other times his language evokes memories of the simpler language of the Septuagint (the Greek translation of the Old Testament). Clearly he saw this as a suitable style for the religious writing in which he was engaged.
Luke's descriptions of Jesus' journey toward Jerusalem and the sacrifice on the cross (Luke 9:51-19:44) are prominent in the literary structure of the Gospel. The sovereignty of God in Jesus' ministry and death is highlighted as Jesus moved toward the city where he would die for sinners (Luke 9:22; 17:25; 18:31-33; cf. Acts 4:28).
Luke also stressed the importance of prayer. He recorded that Jesus prayed before crucial occasions of his ministry. Nine prayers of Jesus are included in the Gospel (seven of which are found only in Luke), along with parables on prayer recorded only in Luke.
Luke was also interested in emotional reactions to Jesus. For instance, only his Gospel includes the magnificent songs of joy that accompanied the birth of the Messiah (Luke 1:46-55, 68-79; 2:14, 29-32).
