The Gospel of Mark was likely written around 50-60 CE in Rome by an unknown author who was possibly Peter's secretary. It was intended for Christians from pagan backgrounds unfamiliar with Jewish customs. As the shortest gospel, it focuses on narrating the kerygma - the story of Jesus' death and resurrection to save humanity. The text explores the "Messianic secret" where Jesus instructs people not to reveal his identity until after his resurrection. It emphasizes Jesus' powerful actions over his teachings and highlights his suffering, death, and ultimate triumph as the revealed Son of God.
