The Jesus-Only doctrine is that which is taught by Oneness Pentecostals such as the United Pentecostal Church and other Apostolic denominations. A variant of Sabellianism, this belief states that there is no distinct person of God the Father, nor God the Holy Spirit, but that the Godhead is comprised solely of Jesus, or "Jesus Only." They believe that God the Father is incarnate in Christ.
Adherents of this doctrine are taught that a person cannot be saved unless this person first forsakes his belief in the Trinity and is rebaptized "in the Name of Jesus only," according to an interpretation of several scriptures, most notably Acts 2:38. In contrast, the baptismal formula accepted by most Christians is found in Matthew 28:19.

The Original Teaching of Jesus Christ (http://www.swami-center.org/en/chpt/jesusteaching/index.shtml) Online book purporting to reconstruct the original teachings of Jesus Christ.
Surely nobody believes that "Jesus Christ" the Son of the living God had to be "born again." Add to that the idea that He took the nature of Satan and became just as vile in His spirit as the devil himself.
The only reasonable explanation of this whole doctrine of a born again Jesus is the rejection of the cross of Jesus Christ.
Jesus was not the "fullness of the Godhead" but the "fullness of the Godhead Bodily." It was in His person as the Son of man to reveal all that God is to the human race.
