Who is “The (Arch)angel of the Lord”?

Such a multiplicity of archangels undermines God’s pre-eminence.   For it inserts created archangelic creatures, or rather man-made items, between Him and all else.

‘The Angel of the Lord’ is the pre-incarnate Second Person of the Trinity.   This is the Son-exalting doctrine of the infallible Word of God.   Genesis 16:7-13; 18:2f,33 to 19:1,27; 22:11-15; 31:11-13; 32:24-30; Exodus 3:2-14; 13:21; 19:3 to 20:19; 23:20-23; Joshua 5:2-15f; Judges 2:1-5; 6:12-23; 13:3-22; Isaiah 63:8-14; and Daniel 3:25; 7:13f; 12:1f.   Also  Zachariah 1:3-16; 2:3-10; 3:1-7; 4:1-7; 5:5-11; 6:4f; 12:8f; Malachi 3:1-5 & 4:2 cf.
