The way, the truth, and the life – Jesus Christ, page-1812

"These acts demonstrated His divine power and authority."

That is a bare face lie and the verse was smack bang in your face, that proves this.
God did the miracles through Jesus, via the Holy Spirit that He is.
God GAVE Jesus the power and authority, and had God so chosen to do so, he could have done this through and given any other man the same.
So, it has zero to do with divine, it was done through him and given to him.

Talk about being creative, goodness me, it doesn't stop.
-------------
The overall of Peters message as he confirmed to Jesus was, that Jesus was the SON of the living God = The Rock.
Not that Jesus was God, or God the Son or God man.
-----------
Ordinary man as in 2nd Adam, but made by the word and power of God = end of story as a 2nd Adam in exactly that.
This 2nd Adam grew in favor with God to the point, that God was well please with him and gave him all power etc and ordained this 2nd Adam Man which you have issues with, like, he couldn't be Just a man, no one could do what Jesus did = WELL, Jesus the MAN out smarted you planted seed, as the Man Jesus did what he did.
And to even suggest as you have, that he would not be an acceptable sacrifice if he was just a man, and you do this will ZERO Bible back up.
Not to mention ignoring Acts 2:24, God being beholding to raise this Man Jesus.

It's like you have missed the plot in why he was made lower than angels, including us, as in God is proving his case to the naughty one.
Ones much lower than the naughty one, will do what you failed to do = case closed.

Has was NOT reduced to being lower than angels, that is all he has ever been.

You want and have created another Jesus, just as the Bible says, some would do, so you are on target there.
