The Gospel of Luke does not identify its author. From Luke 1:1-4 and Acts 1:1-3, it is clear that the same author wrote both Luke and Acts, addressing both to “the most excellent Theophilus,” who was possibly a Roman dignitary. The tradition from the earliest days of the church has been that Luke, a physician and a close companion of the Apostle Paul, wrote both Luke and Acts (Colossians 4:14; 2 Timothy 4:11). This would make Luke the only Gentile to pen any books of Scripture.
The Gospel of Luke was likely written between A.D. 58 and 65.
Purpose of Writing: As with the other two synoptic gospels—Matthew and Mark—this book’s purpose is to reveal the Lord Jesus the Christ and all He “began to do and to teach until the day he was taken up to heaven” (Acts 1:1-2). The Gospel of Luke is unique in that is a meticulous history—an “orderly account” (Luke 1:3) consistent with Luke’s medical mind—often giving details the other accounts omit. Luke’s history of the life of Christ emphasizes His ministry to—and compassion for—Gentiles, Samaritans, women, children, tax collectors, sinners, and others regarded as outcasts in Israel.
Luke is called the most beautiful book ever written, the Gospel of Luke begins by telling us about Jesus' parents; the birth of His cousin, John the Baptist; Mary and Joseph's journey to Bethlehem, where Jesus is born in a manger; and the genealogy of Christ through Mary. Jesus' public ministry reveals His perfect compassion and forgiveness through the stories of the prodigal son, the rich man and Lazarus, and the Good Samaritan.
Many believe in this unprejudiced love that surpasses all human limits, many others—especially the religious leaders—challenge and oppose the claims of Jesus. Christ's followers are encouraged to count the cost of discipleship, while His enemies seek His death on the cross. Finally, Jesus is betrayed, tried, sentenced and crucified. His Resurrection assures the continuation of His ministry of seeking and saving the lost.
Connections: Since Luke was a Gentile, his references to the Old Testament are relatively few compared to those in Matthew's gospel, and most of the OT references are in the words spoken by Jesus rather than in Luke’s narration. Jesus used the Old Testament to defend against Satan’s attacks, answering him with “It is written” (Luke 4:1-13); to identify Himself as the promised Messiah (Luke 4:17-21); to remind the Pharisees of their inability to keep the Law and their need of a Savior (Luke 10:25-28, 18:18-27); and to confound their learning when they tried to trap and trick Him (Luke 20).
