Experts in Greek literary styles acknowledge Luke's style and structure as superb.14No one knows Luke's educational background, but clearly he had training in Greek composition as well as medicine and a talent for writing. Luke used many words that the other Gospel writers did not, and many of them show a wide literary background. He also used several medical and theological terms that are unique. Luke's use of Semiticisms shows that he knew the Hebrew Old Testament well. However, his preference for the Septuagint suggests that it was the version his readers used most. Probably Luke was a Gentile who had much exposure to Semitic idioms from Paul and other Jews. He was a skillful enough writer to use chiasms as a major structural device.15Chiasms were both Jewish and Greek literary devices that gave unity to a composition or section of text. Acts also contains them. Luke also repeated similar stories with variations (cf. 1:80; 2:40; 2:52). This literary device aids learning while giving additional new insights. He also tended to use a particular term frequently in one or more passages and then rarely or never after that. This makes the term stand out and calls attention to it where it occurs.16
