Book of Luke is also the name of a person, Luke.

Luke, a physician, writes with the compassion and warmth of a family doctor as he carefully documents the perfect humanity of the Son of Man, Jesus Christ. Luke emphasizes Jesus' ancestry, birth, and early life before moving carefully and chronologically through His earthly ministry. Growing belief and growing opposition develop side by side. Those who believe are challenged to count the cost of discipleship. Those who oppose will not be satisfied until the Son of Man hangs lifeless on a cross. But the Resurrection insures that His purpose will be fulfilled: "to seek and to save that which was lost" (Luke 19:10).

Kata Loukan, "According to Luke," is the ancient title that was added to this gospel at a very early date. The Greek name Luke appears only three times in the New Testament (Col 4:14; 2Tim 4:11; Phil 24:1)
