The Gospel According to Mark probably dates from 66–70 AD. It does not appear first because it was thought to be a epitome or summary of Matthew, but it is likely the earliest written gospel.
It was probably not written by John Mark the Evangelist, the companion of Peter. It is generally regard it as the work of an unknown author working with various sources that have generally been lost.
It tells us of Jesus' ministry from his baptism by John the Baptist to his death and burial and the discovery of the empty tomb. In it Jesus is a man of action, an exorcist, a healer, and a miracle worker. Jesus keeps his Messianic identity secret, speaking in parables so that even the disciples fail to understand. The gospel in its earliest version end with the discovery of the empty tomb, a promise to meet again in Galilee, and an instruction to spread the good news of the resurrection. There is no genealogy of Jesus or birth narrative, no any post-resurrection appearances. Mark 6:3 is the only place in the New Testament Jesus is referred to as "the son of Mary" and the only gospel where Jesus himself is called a carpenter.
Mark and Luke bear a striking resemblance. Their contents can easily be set side by side in parallel columns.
