Before going further, let us be clear:
Michael is not Jesus Christ.
Throughout the centuries, various theologians and scholars have attempted associating Jesus with angels and angels with Jesus, rather than trying to comprehend the mysteries of the Holy Trinity beginning at its simplest. Jesus is God. If you “see” Him, you see the Father. In other words, although He is the Son, He is also the Father. Therefore, if you are so inclined, you may call Jesus “Abba” or Father. You may also call Jesus mother, brother, sister, and friend, however, none of these descriptors (or others) change the simple fact that He is God. Michael is an angel, a powerful angel, in fact, the most powerful angel in existence. This is only so because God makes it so. Remember, Jesus is God, thus Michael’s powerful existence derives from Jesus as part of the Holy Trinity, the Son of God, or God Himself.
There are Scriptural references describing Michael as an angel/archangel of tremendous importance and favor to God. Surely, these textual references depict him as other than God and a servant by choice. His total submission to God’s will renders him part of that will itself. Are there examples of humans or mortals having attained a similar measure of God-like submission? Yes, indeed. Christ’s own mother is the foremost example of a “yes” to God that mirrors His will as perfectly as possible.
Martyrs, prophets, and saints follow suit, along with a host of other unknown or less famous mortals of phenomenal God-like attributes. And yet Michael, like us, is comprised of free will. He desires us to become angels as well, because such things are possible. Angels may also become like us by choice (or made in God’s image) and without losing their angelic attributes or status. It is the total embrace of the spiritual that enables humans to soar, just as it is the angelic acceptance of our greater, God-like attributes that enable them to become more fully like their Creator. To become like God (which the Father desires for all) is to embrace the best and overcome the worst of whatever being we are made to represent.
