The first three Gospels, i.e., Matthew, Mark and Luke-so called because of the similarity of their contents, statements, and order. The Acts of the Apostles is also attributed to Luke, usually acknowledged to be the same Luke who composed the Gospel. Like the Gospel it was also written in Greek and addressed to the same recipient. Sometimes Acts is referred to as the second half of the Gospel according to Luke, though it is not usually referred to as one of the Synoptic Gospels.
