The Gospel of Luke is the third of the New Testament's four canonical Gospels. It tells of the origins, birth, ministry, death, resurrection, and ascension of Jesus. Together with the Acts of the Apostles, it makes up a two-volume work which scholars call Luke–Acts, accounting for 27.5% of the New Testament.
The text is anonymous, not naming its author. Perhaps most scholars think that he was a companion of Paul, but others cite differences between him and the Pauline epistles. In the popular Two-source hypothesis, Luke used the Gospel of Mark and a hypothetical collection called Q, with unique material often called L, though alternative hypotheses that posit the direct use of Matthew by Luke or vice versa without Q are increasing in popularity within scholarship. Luke follows Mark closely compared to other ancient historians’ usage of sources, though the parallels and variations of the Synoptic gospels are typical of ancient historical biographies. Luke tends to follow his sources closely when checked. The most common dating for its composition is around AD 80–90. The earliest witnesses for the Gospel of Luke are the Alexandrian and the revised western text-type.
