Luke's historical purpose in writing acts was to a) describe the work of christ on earth b) describe the work of christ in the church c) describe the work of christ as a servant d) describe the work of christ as the messiah

B) describe the work of Christ in the church

Explanation:

It is believed by many that Lucas was a doctor who was born in the city of Antioch, which currently belongs to Turkey, although some exegetes and theologians think that Lucas was a Diaspora Jew. Luke is mentioned in Paul's epistles, besides being a man of Greek education and medical profession. He was perhaps also related to Deacon Nicholas (a proselyte of Antioch.) According to tradition, he was a member of the seventy-two, id est to the group of followers of Jesus, but according to exegesis, the dates of the writing of his Works do not match in time. It is also known that, in the writing of his Gospel Luke, he conducted a thorough investigation interviewing people (including the Apostles and perhaps Mary, the mother of Jesus), who witnessed these facts, as can be found in the Prologue of the Gospel and that the Acts of the Apostles is a continuation of it. It is the longest and best written by the refined and balanced use of Greek, as only a cultured and learned person could be expected on such dates. Lucanus (Luke) became a Christian much later and according to tradition he met Mary, the mother of Jesus, on a visit he made with Paul.

the answer is option a.
