Jesus amazed people: A new teaching—and with authority! He even gives orders to impure spirits and they obey him. Mark 1:27
The Gospel of Mark is probably the shortest of the four canonical gospels written about the life of Jesus. This gospel makes no mention of the birth of Jesus and his childhood, but begins its narrative with the beginning of Jesus' public life, his baptism, and the temptation suffered in the desert.
But what this gospel does in its brevity is affirm that Jesus came into the world with a new message, a message of hope against the oppression of his time, a spiritual message condensed into a new spiritual and ethical doctrine, the doctrine of the Kingdom of God, the empire or dominion of the divine perfections. The gospel does not openly affirm the divinity of Jesus, but it suggests it when Jesus on numerous occasions presented himself as God who becomes "son of man", that is, as the personification of the perfections of God, such as when Jesus discussed the meaning of the Sabbath with the Pharisees: "So the Son of Man is Lord even of the Sabbath" Mark 2:28.
The Gospel of Mark recounts that Jesus' words and actions amazed the common and simple people living in and around the region of Galilee. Jesus taught with unusual wisdom and also performed remarkable miracles. The Gospel of Mark recounts that Jesus was teaching in a synagogue in Capernaum, and described the situation with these words: "The people were amazed at his teaching, because he taught them as one who had authority, not as the teachers of the law" Mark 1:22.
The message taught by Jesus was a message destined to change the world, and a miracle performed in the synagogue where he taught caused his fame to spread. Jesus cast out an unclean spirit from a suffering person, and so people said among themselves: "A new teaching—and with authority! He even gives orders to impure spirits and they obey him" Mark 1:27.
Jesus never openly taught that he was the Messiah promised by God to David, but with his teaching, his authority, and his miracles, he invited the children of Israel, the first recipients of his spiritual message, to a new covenant with God, to a new kind of life, the life according to the spirit, to achieve the true goal of man, the gift of eternal life.
