"Jesus Christ, Michael the Archangel does it really matter?
Because at the end of the day he's still our Lord and Saviour. He died on a stake for our sins. He is the image of the Almighty God. So what I want to know is does it matter if he was an angel or not? Tell me what you think?"
Paul, inspired by the Holy Spirit, seemed to think it was important. This is from
2 Corinthians 11:4 "For if someone comes to you and preaches a Jesus other than the Jesus we preached, or if you receive a different spirit from the one you received, or a different gospel from the one you accepted, you put up with it easily enough."
If Paul warns about a different Jesus, then in the end some would have a different Jesus, a Jesus that did not die for their sins.
As for Jesus being God... unless God, speaking in Isaiah 43:10, is dreadfully wrong, there is not a mighty god (Jesus) and an almighty God (the Father). The verse says: "You are my witnesses," declares the LORD, "and my servant whom I have chosen, so that you may know and believe me and understand that I am he. Before me no god was formed, nor will there be one after me."
And if Jesus is a created being John 1:3 is in trouble, it says: "Through him all things were made; without him nothing was made that has been made."
If that verse is true, then everything that had a point of creation was created by Jesus, and since it's illogical for Jesus to have created himself, he has to be an eternal being. Which is good because he's called the Word of God and the Wisdom of God, and since there was never a time when God didn't have His Word, or his Wisdom, that fits nicely.
Jesus is God in human flesh.
