Humans are not angels. Nor are they called angels anywhere in the Bible.
I take the Bible at its Word, and the angel of the Lord is the angel of the Lord, not Jesus. We CAN over-think these things, you know.
Remember that Christ while being fully human was ALSO fully DIVINE.
Yes, he might have appeared as an angel.
Then to whom is Jesus communicating via John in the first chapters of Revelation, when He dictates letters to the "angel" of each of the seven churches?
The difficulty here is that there are beings to whom the name "angels" has been given, and then there is the use of the term "angel" in its original sense of being the messenger, just as there are lions who are a specific type of being, and then there are those like the Lion of the Tribe of Judah who is not a lion, but who performs the function symbolized by a lion.
We cannot hope to fathom the mind of God, nor do we need to.
One pastor I heard taught that when Jacob wrestled with God, it was actually Jesus, so we can debate all we want but generally people believe what makes them comfortable. Those things that require faith are generally uncomfortable. I was surprised at the way the word “God” is used in the OT from my concordance and I love my concordance. Gen 32 I guess I’ll look up Messenger but if someone from the State Department says something, isn’t it perceived as coming from the President (if there is one).
Second, you are simply wrong about humans not being called angels in the Bible -- the Greek word ἄγγελος is simply the word for messenger, and is applied to John the Baptist in Mark's and Matthew's Gospels, in Luke's Gospel to the men John the Baptist sent to inquire of Jesus whether he were the Christ, in the Universal Epistle of James to the Israelite spies whom Rahab aided, and, despite protestants objecting to this out of historical ignorance, to the bishops of the Churches of Asia Minor to whom St. John the Theologian addressed his Apocalypse.
The custom of referring to the bishop of a church as the "angel" of the church is very ancient, but is preserved to this day in the title of "The Angel of Haran" applied to the Orthodox bishop of the Diocese of Bosra-Haran in Syria.
