There is but one Archangel named.
There is no Scripture that names the pre/post human Jesus as Michael so any association between the two must be by inference.
The Book of Daniel calls Michael a “foremost prince” who would stand up for Israel. (Dan. 10)
In Jude, Michael is said to have had a dispute with the Devil over the disposition of Moses’ body.
Paul said Jesus would come with “an arch angel's voice”
(1 Thess. 4:16)
Rev. 12 describes Michael battling Satan and tossing him out of heaven while Rev. 19 describes Jesus as the Word battling God's enemies.
Not proof but not an unreasonable association either considering the amount of information available.
Now, May I inquire the reason for your curiosity.
On Michael the Archangel
OK, the reason for my curiosity about what you believe about Jesus being Michael is two-fold. First, upon reviewing your argument, I agree it falls far short of proof, and I am a bit surprised that you hold a theological belief you admit you cannot prove from Scripture.
So my follow-up question would be this: Given that you have accepted the Watchtowers Michael theory on such admittedly weak grounds, is this because you believe they have unique authority to speak as the voice of God on earth today?
Because if you do see them that way, Id like to get your input on the following quote:
This is a campaign extraordinaire, one that will be memorialized for all time. Wave upon wave of insects, most prominently locusts, devastate the land. What does this mean? Revelation 9:1-12 also speaks of a plague of locusts, sent forth by Jehovah under “a king, the angel of the abyss,” who is none other than Christ Jesus. His names Abaddon (Hebrew) and Apollyon (Greek) mean “Destruction” and “Destroyer.” These locusts picture the anointed remnant of Christians who, now in the Lord’s day, go forth to devastate Christendom’s pastures by completely exposing false religion and proclaiming Jehovah’s vengeance upon it. — Watchtower 5/1/1992
So is Jesus Michael, or Abaddon/Appolyon, or both, in your view?
