I was talking specifically about the phrase "the angel of the LORD," found in Genesis 16, Genesis 22, Exodus 3, Numbers 22, etc.
Like I said, Christians have traditionally understood that phrase as referring to the pre-incarnate Second Person of the Trinity. Even the Jewish philosopher Philo agreed that it referred to someone greater than just an angel.
Well, they are wrong, well, not exactly wrong, cause God/Jesus/YHWH is the good angels, cause they (God/YHWH/Jesus) (or the triune God) is "all" of them (the good angels) but "all" of them, (the good angels) are not "all" of what God is...
And the scriptures says "angel" and it doesn't really matter if it says "the" angel, or not, it still says "angel" and Jesus/God/YHWH is not an angel, and they're saying that it (the angel of the Lord) is greater than an angel, does not change the fact that it still says "angel" and angels are created beings, whether it is "the" or "a" doesn't matter cause God/Jesus/YHWH is not any angel (yet they are), they are not "just an" angel, being uncreated beings with no beginning or ending...
The Jewish Philosopher was wrong basically, he obviously didn't see Jesus as YHWH, yet he thought Jesus was greater than the angels but not YHWH, and so, he added the fact basically saying "well, although it says "angel" It must not be, or mean, an angel only, cause he thought it to be Christ, and Christ was uncreated, yet not YHWH, ect, ect...
He did not have the revelation that YHWH is Jesus and is not exactly the Father, but the Son... Yet the Father and the Holy Spirit were one with YHWH or God the Son, or Jesus, before he was Jesus and they were with him (Jesus) as YHWH...
They (your philosophers and theologians) were grasping at straws in my opinion, by not being able to come to the revelation that Jesus is/was YHWH, and not any angel, but God, who is not any angel, not being a created being, even "the" angel (and notice it says, "of the Lord" or an angel of Jesus/God/YHWH)...
The fact that it says "the", only means that it was a very high angel, like an archangel, yet not God, and "the angel" is not Jesus, cause Jesus is God, and uncreated and has no beginning or end, like angels (any angel) do, so...
No! The angels are created beings.
The idea that angels are "extensions of God" is not only heretical, it gets you into terrible trouble explaining what fallen angels are.
Fallen angels forsook of left their proper dwelling places in the Body of God, and became no longer a part of him (God) and separated from him (God)... No longer extensions of God, no longer in God's will, like the good angels always and continually are...
The good angels have no will of their own at all, ever, they always, always do what God commands, so that if they do a thing, it is just like, and just as if it was or is God doing it...
God Bless!
