Ok, but what you are failing to say here is what the anointing is. When scripture says, 'the Spirit of the LORD was upon...' it means that God has anointed a person with his Holy Spirit. The outward use of oil is simply the symbolism. The reality is the inner illumination of God's Word to man's spirit and soul.
If you do not believe that the Messiah is more than a human king, then you, too, condemn yourself to a sinful imposter!
Jesus (a) is yet to play the role of the Messiah predicted as in the one who will rule the world from the offspring of David (a). This is why he's coming back.
The Mahdi (a) for example in Islam, is alive and on earth, but he hasn't fulfilled the promises regarding him by the Prophet (a).
A more fruitful discussion, would be, are the Gospels from God or not? If they are from God, then he is a Prophet and his words about himself are true. If not, then he isn't.
