...the quote I referenced was talking about their being no need for a saviour if Jesus was not Michael
I understand your reasoning. Further, Jesus redemption is basterdized by WT doctrine because they have Jesus being raised as a spirit. Not a fleshly resurection, thus perpetrating a colossal fraud of Jesus finding another body with matching flesh wounds.
The WT has the audacity to claim if Jesus rose in the "flesh" he would be "taking back the ransom" hence the fraudulent apperances.
I perceive 'archangel' to be a title rather than a nature (such as human, spirit etc.). As such the question regarding what happened to Michael the Archangel if he is Jesus is the same as asking what happened to the pre-existent Jesus when he became flesh.
The JW cannot have Jesus on earth with a dual nature. With that Michael has to be out of the picture for the earthly Jesus to exist. Remember JW doctrine Jesus was Just a man. Also, after his death, his body turned into gases so Jesus is gone forever, now Michael has to continue on in heaven.
The angels in Noahs day were able to take on bodies (and have a dual nature) and leave without changing natures. But Jesus is somehow unable to do this?????
what happened to the pre-existent Jesus when he became flesh.
Its my belief Jesus was not in heaven when he was on earth, and it was Jesus blood that saves not Michaels. And Jesus not Michael is above all authority named. Ephesians 1:20
