Jesus is God's Son,not an angel.Hebrews makes that very clear.
Hebrews 1:5-13
For to which of the angels did He ever say: “You are My Son, today I have begotten You”? And again: “I will be to Him a Father, and He shall be to Me a Son”? But when He again brings the firstborn into the world, He says: “Let all the angels of God worship Him.” And of the angels He says: “Who makes His angels spirits and His ministers a flame of fire.” But to the Son He says: “Your throne, O God, is forever and ever; a scepter of righteousness is the scepter of Your kingdom. You have loved righteousness and hated lawlessness; therefore God, Your God, has anointed You with the oil of gladness more than Your companions.” And: “You, Lord, in the beginning laid the foundation of the earth, and the heavens are the work of Your hands. They will perish, but You remain; and they will all grow old like a garment; like a cloak You will fold them up, and they will be changed. But You are the same, and Your years will not fail.” But to which of the angels has He ever said: “Sit at My right hand, till I make Your enemies Your footstool”?
Another proof that Jesus is not Michael the archangel actually comes from one of the five passages in which Michael’s name is found in Scripture—Jude 9. According to Jude: “Michael the archangel, in contending with the devil, when he disputed about the body of Moses, dared not bring against him a reviling accusation, but said, ‘The Lord rebuke you!’ ” Whereas Michael would not dare pronounce a railing judgment against the devil (cf. 2 Peter 2:11), Jesus once declared about Satan: “He was a murderer from the beginning, and does not stand in the truth, because there is no truth in him. When he speaks a lie, he speaks from his own resources, for he is a liar and the father of it” (John 8:44). Jesus did not approach the subject of rebuking Satan with the same hesitation as godly angels like Michael. Jesus, as Lord of heaven and Earth (Matthew 28:18), boldly called the devil a murderer and liar, and even went so far as to declare that “there is no truth in him.” The Son of God obviously is not Michael the archangel.
Interestingly, John H. Paton, the most frequently used contributing writer in 1879 of Charles Taze Russel (the founder of The Watchtower Bible and Tract Society), admitted such when he stated in The Watchtower magazine near the end of its inaugural year: “Hence it is said, ‘let all the angels of God worship him’: (that must include Michael, the chief angel, hence Michael is not the Son of God)…” (1879, p. 4, emp. added).
