Most scholars hold to the two-source hypothesis, which claims that the Gospel of Mark was written first. According to the hypothesis, the authors of the Gospel of Matthew and the Gospel of Luke then used the Gospel of Mark and the hypothetical Q document, in addition to some other sources, to write their individual gospel accounts.[57][58][59][60][61] These three gospels are called the Synoptic gospels because they include many of the same stories, often in the same sequence, and sometimes exactly the same wording.
