Here's an answer you might need if a Jehovah's Witness comes to your door.
This question is about Jesus and Michael the archangel, which is an issue for Jehovah's Witnesses who think, as I recall, that Jesus is an incarnation of Michael the Archangel. He's a created being, he is not God incarnate, the Creator of all things, the same one who was there in the beginning when God created the heavens and the earth, he is a created being.
The question says if Jesus is the chief of the Angels as indicated in Joshua 5, why can't he be Michael the archangel who is a head angel? The answer is, to be chief of the angels doesn't mean that you're also an angel. If Jesus is the chief of the angels, Michael the archangel is under Jesus.
We know who Jesus is from other scriptures. “In the beginning was the Word, and the Word was with God, and the Word was God. All things came into being through him; Apart from him nothing came into being that has come into being.” In other words, he is the uncreated creator from John 1:1-3.
John 1:14 says, “The Word became flesh and dwelt among us. We beheld his glory, the glory the only begotten Son of the Father, full of grace and truth.”
Jesus is God. He can also be the chief of the angels, but that doesn't mean that he's an angel. That means even Michael the archangel would be under the chief of the angels.
