Kenneson,
If Michael was Christ before coming to earth then he was Michael when on earth and Michael when he went back to the Father. You can't have Michael living in heaven and Christ simultaneously living on earth because that makes two persons, not one. Whereas angels in the Old Testament appear to materialize, this is not what happened to the Christ as Scriptures say he was born of a woman. Gal. 4:4
What I meant was that the name Michael was I believe the name of Jesus before coming to the earth. Of course they are not two persons. For those who do not believe in the Trinity, like myself, Jesus had a life in the heavens in a spirit body before coming here, as all God's heavenly sons have also. Was God's firstborn heavenly Son's name, Jesus, meaning God Saves, prior to his coming to earth? Maybe some believe that I don't know. I just happen to believe his name was Michael.
