Phil,
Those are great points you brought out. Jesus was exalted as you pointed out so that his name is above all others at this time. We know he is the head of the Church and our future king.
But, none of the "exalting" of Jesus mentioned in Hebrews points to the fact that he had to be a lower nature as an Angel prior to this. As the only begotten Son of God, he is and always was the divine Son. The one and only eternal son of God.
My understanding of Hebrews 1 is that Jesus as the eternal son is being contrasted to the other sons of God who are Angels. And in this contrast the writer is showing Jesus superiority.
But, I can be wrong, like you said. People interpret the bible scriptures in different ways. However, I don't feel I am wrong when I state that not one scripture of our official bible cannon gives support to Jesus being Michael teaching. And the view that Jesus was created or had a beginning is an Arian view and a heresy according to the early church. Jesus is not an Archangel, he is the eternal Son of God. Way superior to any of the Angels or Archangels.
This is the accepted view of most of Christendom, mostly all (if not all) Bible Scholars and the early church supports Jesus as being eternal and not created. But I can appreciate the fact that you are entitled to your own opinion and interpretation of scripture. And I can respect that. I am not trying to change your personal views. I am merely trying to respond to the topic brought up in this thread about Jesus being Michael.
Personally I have examined all 6 scriptural texts used to support this view and I feel you have to read into them something that is not there. And I believe this is what Russell did and the groups he fathered, JW's and Bible Student groups to this day, are repeating Russell's error. But this is only my opinion and may not be shared by others.
Peace, Lilly
