The Gospel of Mark introduces Jesus as the Messiah and Son of God. However, Mark explores the complexity of Jesus' identity through themes like the "messianic secret" where Jesus commands silence about his identity, and the repeated failure of people to recognize who Jesus is. Scholars believe Mark was written around 65-75 CE based on references to the destruction of the Jerusalem temple in 70 CE. The earliest and briefest of the gospels, Mark provides important context for understanding Jesus while posing theological questions through its narration.
