Mark is known as Peter's interpreter, both in speech and in writing. As a fisherman from Galilee, Peter may not have spoken Greek fluently, so Mark interpreted for him. In his book, Mark wrote down the observations and memories of Peter, one of the original Apostles.

In summary, Mark's Gospel is a narrative proclamation that Jesus is the Messiah and Son of God, whose death and resurrection paid the penalty for our sins and achieved victory over Satan, sin, and death. With this joyful announcement comes the call to all believers for faith and cross-bearing discipleship.

Mark's gospel was probably written around 70 CE, placing its writing at about the time of the destruction of the Temple in Jerusalem. According to early tradition the gospel was written by Mark, a disciple of Peter.

Mark's Gospel is even more oriented to christology. Jesus is the Son of God (Mk 1:11; 9:7; 15:39; cf. Mk 1:1; 14:61). He is the Messiah, the anointed king of Davidic descent (Mk 12:35; 15:32), the Greek for which, Christos, has, by the time Mark wrote, become in effect a proper name (Mk 1:1; 9:41).
