This document provides an overview and analysis of the Gospel of Matthew, Mark, and Luke from the New Testament. It discusses the traditional views on authorship for each gospel and analyzes both internal and external evidence. For Matthew, the author concludes it was most likely written by the disciple Matthew between AD 50-70 in Antioch. For Mark, the author finds compelling evidence that it was written by John Mark around AD 65-70 in Rome based on his relationship to Peter. For Luke, the author determines Luke the physician wrote it between the late 60s-70s based on his relationship to Paul and intent to provide an orderly account for Theophilus.
