There are some religions that believe Michael incarnated as Jesus and returned to spirit being status.

Its origin appears to come from 7th Day Adventists

The blog “John 1:1 – The Glue” describes Jesus’ current state of being that hasn’t changed since birth(Heb 13:8,  Luke 24:36-39, John 20:27, 1 Tim 2:5; flesh and bone no blood, the mediator between God and man)  and the blog “church of Christ” mentions Heb 1:5 (God does not let an angel sit beside Him).

Here is a comparison of what Michael said vs what Jesus said:

Jude 9New International Version (NIV)

But even the archangel Michael, when he was disputing with the devil about the body of Moses, did not himself dare to condemn him for slander but said, “The Lord rebuke you!”[a]

Matthew 4:10New International Version (NIV)

10 Jesus said to him, “Away from me, Satan! For it is written: ‘Worship the Lord your God, and serve him only.’[a]

Jesus is also called “Lord” throughout the entire bible (Phil 2:11 and Mark 16:19 being two and Acts 20:28 ASV implying Jesus is Lord) and He directly rebuked Satan.

1 Thessalonians 4:16New International Version (NIV)

16 For the Lord himself will come down from heaven, with a loud command, with the voice of the archangel and with the trumpet call of God, and the dead in Christ will rise first.

The Lord is Jesus.  So how can Michael be Jesus if he says “the Lord rebuke you?”

Revelation 12:7-9New International Version (NIV)

Then war broke out in heaven. Michael and his angels fought against the dragon, and the dragon and his angels fought back. But he was not strong enough, and they lost their place in heaven. The great dragon was hurled down—that ancient serpent called the devil, or Satan, who leads the whole world astray. He was hurled to the earth, and his angels with him.

The above confirms Michael is the archangel.  This event in time had to occur BEFORE man was created.   Satan and his angels (this include the beast and false prophets) have been on earth since the beginning and the first ones deceived were Adam and Eve.

In Daniel 10, Michael is an earthly prince. GNT translates “princes” to “angels”

Daniel 10:13New International Version (NIV)

13 But the prince of the Persian kingdom resisted me twenty-one days. Then Michael, one of the chief princes, came to help me, because I was detained there with the king of Persia.

Daniel 12New International Version (NIV)

The End Times

12 “At that time Michael, the great prince who protects your people, will arise. There will be a time of distress such as has not happened from the beginning of nations until then. But at that time your people—everyone whose name is found written in the book—will be delivered. Multitudes who sleep in the dust of the earth will awake: some to everlasting life, others to shame and everlasting contempt.

They will attempt to use this to equate Jesus to Michael.  Here is the issue: Jesus was resurrected 3 days after He died.  This verse would indicate that Michael would possibly arise at the 2nd resurrection and may even possibly be the final angel from the east in Rev 7:2-3.

Jesus has been seated at the right hand of the Father for 1982 years approx.  He comes down in 1 Thess 4:16-17.

Jesus is called Lord in Phil 2:8-11 and Acts 20:28 ASV says “church of the Lord which he has purchased with his own blood.” 1 Cor 10:9 says “do not tempt Christ” in some translations and “do not tempt the Lord” in others.

They also try to equate Rev 19:11-16 with Jesus being Michael.

Revelation 19:11-16King James Version (KJV)

11 And I saw heaven opened, and behold a white horse; and he that sat upon him was called Faithful and True, and in righteousness he doth judge and make war. 12 His eyes were as a flame of fire, and on his head were many crowns; and he had a name written, that no man knew, but he himself. 13 And he was clothed with a vesture dipped in blood: and his name is called The Word of God. 14 And the armies which were in heaven followed him upon white horses, clothed in fine linen, white and clean. 15 And out of his mouth goeth a sharp sword, that with it he should smite the nations: and he shall rule them with a rod of iron: and he treadeth the winepress of the fierceness and wrath of Almighty God. 16 And he hath on his vesture and on his thigh a name written, King Of Kings, And Lord Of Lords.

Verse 16 alone would dispute Michael being Jesus since the title is “Lord of Lords.”  This event could be equated to the final battle between good and evil.

Angels will be judged:

1 Corinthians 6:2-4King James Version (KJV)

Do ye not know that the saints shall judge the world? and if the world shall be judged by you, are ye unworthy to judge the smallest matters? Know ye not that we shall judge angels? how much more things that pertain to this life? If then ye have judgments of things pertaining to this life, set them to judge who are least esteemed in the church.

How could an angel judge another angel?

Some might try to use Luke 2:21 KJV to show Jesus is an angel; however, NIV states more clearly that Jesus was called that name by an angel before birth.

Luke 2:21New International Version (NIV)

21 On the eighth day, when it was time to circumcise the child, he was named Jesus, the name the angel had given him before he was conceived. there are some verses that dispute Michael being Jesus.
