He claims to be the "Lord of the Second Advent", in order to complete the task in which Jesus failed. Moon states that there is no reason for Jesus to return, since Moon himself will usher in salvation.
Moon is a satanically deluded nutcase who blasphemes every time that he opens his mouth. He denies the perfection and diety of Jesus Christ, and elevates himself above the true Prince of Peace. As such, he is an antichrist, against which the New Testament gives numerous warnings.
His contemporaries said precisely the same thing about Jesus.
