Only that Angel named Michael is the only Biblical Archangel.
And,
Revelation 12:7, . . . Michael and his angels . . . .
What is the argument that the Archangel Michael can not be the Angel of the LORD?
Hebrews 1:5
For unto which of the angels said he at any time, Thou art my Son, this day have I begotten thee? And again, I will be to him a Father, and he shall be to me a Son?
Hebrews 1:13
But to which of the angels said he at any time, Sit on my right hand, until I make thine enemies thy footstool?
Were Jesus an angel, Michael would be that answer according to your reasoning.
It is no surprise that there is only one archangel. The description is that of one angel over the rest. Were there two or three archangels, we would need to redefine the word.
