The first three gospels are called the "synoptics", from a Greek phrase meaning "seen together", because they put the events of Jesus' life in the same order and have many of the same stories and sayings, often in the same or very similar words.The usual way of explaining this is that Mark was written first, and that the authors of Matthew and Luke, acting independently, used Mark plus a collection of sayings called the Q document and additional material unique to each called the M source (Matthew) and the L source (Luke).He preached first in Galilee and later in Jerusalem, where he cleansed the temple.He states that he offers no sign as proof (Mark) or only the sign of Jonah (Matthew and Luke).The Gospel of Judas is another controversial and ancient text that purports to tell the story of the gospel from the perspective of Judas, the disciple who is usually said to have betrayed Jesus.It paints an unusual picture of the relationship between Jesus and Judas, in that it appears to interpret Judas's act not as betrayal, but rather as an act of obedience to the instructions of Jesus.
For the Good News of salvation through Jesus, The gospel.
Jesus preaches in Jerusalem, launching his ministry with the cleansing of the temple.
He performs several miracles as signs, most of them not found in the synoptics.
Luke, while following Mark's plot more faithfully than does Matthew, has expanded on the source, corrected Mark's grammar and syntax, and eliminating some passages entirely, notably most of chapters 6 and 7, which he apparently felt reflected poorly on the disciples and painted Jesus too much like a magician.
The synoptic gospels represent Jesus as an exorcist and healer who preached in parables about the coming Kingdom of God.
