The gospel of Luke is the only book of the New Testament that was written by a Gentile. Luke was a physician who never met Jesus, and was not an eyewitness of the events of the gospel account. He was a dear friend of the apostle Paul and probably traveled with him on his last two missionary journeys. Luke was writing as a historian who had compiled the accounts of others after careful research. He addressed this book and its sequel, the book of Acts, to Theophilus, who was probably an early Greek believer. Luke's intent was to confirm to Theophilus that the events he recorded were absolutely true. While Matthew presented Jesus as the Jewish Messiah and King, and Mark painted the picture of Jesus as a Servant, Luke emphasized the humanity of Jesus, and presented Him as the perfect Man. And who would be better qualified to bear witness to the humanity of Jesus than a physician? Luke wrote in a very high form of Greek, with a very sophisticated vocabulary. He used numerous medical terms, as one might expect. The Greeks were obsessed with humanity and the quest for perfect humanity, and Luke wanted to show them Jesus, the perfect Man.
