Jesus scandalized some Jews of his own time by claiming
to have the authority to forgive sins.
Mark 2:7
Why does this man speak that way? He is blaspheming.
Who but God alone can forgive sins?
Jesus clearly stated that he had the authority to forgive sins.
Mark 2:10-12
    "But that you may know that the Son of Man has
    authority to forgive sins on earth"-- he said to the
    paralytic, "I say to you, rise, pick up your mat, and
    go home." He rose, picked up his mat at once, and
    went away in the sight of everyone.
