The Gospel according to Mark is the second book in the New Testament.
Saint Mark [Lat. Marcus], Christian apostle, traditional author of the 2d Gospel (see Mark, Gospel according to). His full name was John Mark. His mother, named Mary, had a house in Jerusalem, which the Christians used as a meeting place. Mark accompanied St. Paul and St. Barnabas, who was his cousin or uncle, on their mission to Cyprus, but he left them at Perga and returned to Jerusalem. Paul refused to take Mark on his second trip, thus creating a breach with Barnabas. Tradition identifies Mark with the young man who "fled from them naked" at Gethsemane. Tradition also makes him an associate of St. Peter, who is thought to have furnished many of the evangelist's facts. The Alexandrian church claims Mark as its founder—the liturgy of that church is called the Liturgy of St. Mark. St. Mark is the patron of Venice and of its famous cathedral, where his relics are shown. His symbol as an evangelist is a lion. Feast: Apr. 25.
