Unlike Y’shua, angels are “mere created” beings that YHWH created before He created the physical universe for a specific purpose. The book of Job describes the angels worshiping God as He was creating the world (Job 38:4-7). One of their duties was to be “ministering spirits sent to serve those who will inherit salvation” (Hebrews 1:14). We also know they existed prior to the Garden of Eden, because Satan, who was formerly the angel Lucifer, was already present in the Garden in his fallen state. However, because another function of angels is to worship God around His throne (Revelation 5:11-14), they may have been in existence millions of years—as we reckon time—before God created the world, worshiping Him and serving Him.
Yes, in Exodus 23:20-22 we see Him referred to as a Messenger, but there is a major difference between Y'shua and the angels. For one thing, Y'shua (whose Name means "YHWH is Salvation) is the ONLY Divine Being who has YHWH's Name within His own. Messengers, on the other hand, have the name EL (short for ELOHIM) in their names (Micha-el, Gabri-el, Rapha-el). Furthermore, in Exodus 23:20-22 we are told that unlike every other "angel" He could forgive sin, "for My Name is in him" and that Name is YHWH, the Name above all Names including that of the angels (Hebrews 1, Philippians 2:6-11).
Y'shua was the Thought before he was the Word and the Word made flesh (John 17, Revelation 19:13) and He was with YHWH from the beginning and thus was YHWH (not "created"). Isaiah 53:1 tells us He was "an arm" of YHWH. And check this out – Scripture tells us He is YHWH – as we cannot separate Him from YHWH. Yes, in his human form He was different from YHWH, but His qnoma (nature) was divine because He was a part of YHWH:
Philippians 2:5 And think you so in yourselves, as Y'shua the Mashiyach also thought; 6. who, as he was in the likeness of Elohim, did not regard it sinful to be the coequal of Elohim; 7. yet disinherited himself and assumed the likeness of a servant, and was in the likeness of men and was found in fashion as a man; 8. and he humbled himself and became obedient to death, even the death of the stake. 9. Wherefore, also, Elohim has highly exalted him and given him a name which is more excellent than all names; 10. that at the name of Y'shua every knee should bow, of (beings) in heaven and on earth and under the earth; 11. and that every tongue should confess that Y'shua the Mashiyach is YHWH, to the glory of Elohim his Father. (AENT)
Colossians 1: 15. who is the likeness of the invisible Elohim and the first-born of all creatures: 16. and by him was created everything that is in heaven and on earth, all that is visible and all that is invisible, whether thrones or dominions or principalities or powers; everything was through him and was created by him: 17. and he was prior to all, and by him everything exists. 18. And he is the head of the body the Assembly; as he is the head and first-born from among the dead, that he might be the first in all things. 19. For it pleased (the Father) that in him all fullness should dwell; 20. and by him, to reconcile all things to himself; and through him he has pacified, with the blood of his stake, both (those) on earth and those in heaven.(1) (AENT)
Footnote: Mashiyach is the creative Word through which everything was made (Psalm 33:6, John 1:1-5, Hebrews 1:1-5). The common Aramaic idiom here and in John is "through his hands" meaning as the Word, Mashiyach crafted all things according to YHWH's blueprints. Mashiyach Yeshua emerges as the Word from YHWH's breath and command and, as such, was with Him in the beginning (John 17:1-11).
And let's not forget: Hebrews 1 tells us He is higher than the angels!
Hebrews 1:1. In many ways and many forms, Elohim anciently conversed with our fathers by the prophets: 2. But in these latter days, He has conversed with us by His Son whom He has constituted heir of all things, and by whom He made the worlds; 3. who is the splendor of His glory and the exact image of His nature, and upholds all by the power of His Word; and by his Qnoma he made a purification of sins and sat down on the right hand of the Majesty on high. 4. And he is altogether superior to the Messengers, as he has also inherited a name which is superior to theirs.
5. For to which of the Messengers did Elohim ever say, You are my Son, this day have I begotten you? And again, I will be to him a Father, and he will be to me a Son? 6. And again, when bringing the first begotten into the world, He said: Let all the Messengers of Elohim worship him. 7. But of the Messengers He thus said: Who made His Messengers a wind and His ministers a flaming fire. 8. But of the Son He said: Your throne, O Elohim, is for ever and ever; a righteous scepter is the scepter of your Kingdom. 9. You have loved righteousness and hated iniquity; therefore Elohim, your Elohim, has anointed you with the oil of rejoicing more than your associates.
10. And again, You have from the beginning laid the foundations of the earth and the heavens are the work of your hands: 11. they will pass away, but you endure; and they all, like a robe, wax old; 12. and like a cloak, you will fold them up. They will be changed; but you will be as you are, and your years will not be finished. 13 And to which of the Messengers did He ever say: Sit you at My right hand until I will place your enemies a footstool under your feet? 14. Are they not all spirits of ministration who are sent to minister on account of them that are to inherit life? (AENT)
Footnote: Acharit-hayamim (latter days, verse 2 above) is mentioned throughout Torah and the Prophets beginning in B’resheet Genesis 49:1. See also James 5:3; 2 Peter 3:3. This era culminates with the Day of YHWH which is foreshadowed by Yom Kippur when all the earth shall be sanctified.
