Jesus and Michael the Archangel - the same person?
Scriptural evidence indicates that the name Michael applied to God's Son before he left heaven to become Jesus Christ and also after his return.
But first it is helpful to understand more about THE Archangel:
The prefix "arch," means "chief" or "principal,"

and implies that there is only ONE Archangel, the chief angel; in the Scriptures. Further implying that there is only one Archangel is that the word "Archangel" is never found in the plural.
So because this evidence demonstrates that there is only ONE Archangel (compare Jude 9, "Michael THE Archangel"), when the voice of the resurrected Lord Jesus Christ is also described as being that of the "Archangel" at 1 Thessalonians 4:16, this suggests that he is, in fact, himself the Archangel.
Scholars' Quotes Concerning Jesus as Michael the Archangel
From early Christian writings until now there have been many who understood Michael to be the archangel who became Jesus on earth.
Early Christian scholar Origen writes:
"There are certain creatures, rational and divine, which are called powers [spirit creatures, probably angels]; and of these Christ was the highest and best and is called not only the wisdom of God but also His power." - ANF 10:321-322.
-----------------------------------
Back in the early 1800's, Bible scholar Joseph Benson stated that the description of Michael as found in the Bible "manifestly points out the Messiah."
-----------------------------------
Nineteenth-century Lutheran E. W. Hengstenberg agreed that "Michael is no other than Christ."
-----------------------------------
Similarly, theologian J. P. Lange, when commenting on Revelation 12:7, wrote: "We take it that Michael . . . is, from the outset, Christ in warlike array against Satan."

Clarke’s Commentary (Adam Clarke)
Jude :9
“Let it be observed that the word archangel is never found in the plural number in the sacred writings. There can be properly only one archangel, one chief or head of all the angelic host. Nor is the word devil, as applied to the great enemy of mankind, ever found in the plural; there can be but one monarch of all fallen spirits. Michael is this archangel, and head of all the angelic orders; the devil, great dragon, or Satan, is head of all the diabolic orders. When these two hosts are opposed to each other they are said to act under these two chiefs, as leaders; hence in Revelation 12:7, it is said: MICHAEL and his angels fought against the DRAGON and his angels. The word Michael lakym, seems to be compounded of ym mi, who, k ke, like, and la El, God; he who is like God; hence by this personage, in the Apocalypse, many understand the Lord Jesus.”

The 1599 Geneva Study Bible: Revelation
“12:7 And there was war in heaven: 14 Michael and his angels fought against the dragon; and the dragon fought and his angels,
“(14) Christ is the Prince of angels and head of the Church, who bears that iron rod….”

John Gill, A Body of Doctrinal Divinity, Book 7 Chapter 5:
“1b2. Another prophecy in Daniel 12:1-3 respects the second and personal coming of Christ; for he is meant by Michael, who is "as God", as his name signifies, equal to him; the ‘great prince,’ the prince of the kings of the earth, and the head of all principalities and powers.”
John Gill's Exposition of the Entire Bible
Daniel 12:1
“Ver. 1.
And at that time shall Michael stand up,.... The Archangel, who has all the angels of heaven under him, and at his command, the Son of God, our Lord Jesus Christ;”
And even trinitarian Bible scholar W. E. Vine (“recognized as one of the world’s foremost [Bible] Greek scholars”) tells us that this “voice of the archangel” (1 Thess. 4:16) is apparently “the voice of the Lord Jesus Christ”! - p. 64, An Expository Dictionary of New Testament Words.
--------------------------------------
The International Standard Bible Encyclopaedia:
“The earlier Protestant scholars usually identified Michael with the preincarnate Christ, finding support for their view, not only in the juxtaposition of the “child” and the archangel in Rev. 12, but also in the attributes ascribed to him in Daniel” – vol. 3, p. 2048, Eerdmans Publishing, 1984 printing.

Protestant Reformer John Calvin said regarding "Michael" in its occurrence at Daniel 12:1:
"I embrace the opinion of those who refer this to the person of Christ, because it suits the subject best to represent him as standing forward for the defense of his elect people." - J. Calvin, Commentaries On The Book Of The Prophet Daniel, trans. T. Myers (Grand Rapids: Baker Book House, 1979), vol. 2 p. 369.

John Wesley:
Chapter XII
A promise of deliverance, and of a joyful resurrection, ver. 1 - 4. A conference concerning the time of these events, ver. 5 - 7. An answer to Daniel's enquiry, ver. 8 - 13. For the children - The meaning seems to be, as after the death of Antiochus the Jews had some deliverance, so there will be yet a greater deliverance to the people of God, when Michael your prince, the Messiah shall appear for your salvation. A time of trouble - A the siege of Jerusalem, before the final judgment. The phrase at that time, probably includes all the time of Christ, from his first, to his last coming.
Wesley on Daniel 10:21: "Michael - Christ alone is the protector of his church, when all the princes of the earth desert or oppose it."
