And by this logic, Jesus was also simply parroting what he read about future prophecy.
Jesus saith unto him, Thou hast said: nevertheless I say unto you, Hereafter shall ye see the Son of man sitting on the right hand of power, and coming in the clouds of heaven.
- Matthew 26:64
When all the people were baptized, it came to pass that Jesus also was baptized; and while He prayed, the heaven was opened. And the Holy Spirit descended in bodily form like a dove upon Him, and a voice came from heaven which said, “You are My beloved Son; in You I am well pleased.” - Luke 3:21-22
Then Jesus, being filled with the Holy Spirit, returned from the Jordan and was led by the Spirit into the wilderness, being tempted for forty days by the devil. And in those days He ate nothing, and afterward, when they had ended, He was hungry. And the devil said to Him, “If You are the Son of God, command this stone to become bread.” But Jesus answered him, saying, “It is written, ‘Man shall not live by bread alone, but by every word of God.’ ” - Luke 4:1-4
Maybe Jesus was just winging it when he proclaimed he was the fulfillment of scripture?
Really... did he know these things were true or not?
So He came to Nazareth, where He had been brought up. And as His custom was, He went into the synagogue on the Sabbath day, and stood up to read. And He was handed the book of the prophet Isaiah. And when He had opened the book, He found the place where it was written:
But Jesus did have authority. Because He was the Son of God, and one with God.
He was the Word made Flesh. (John 1)
For if you believed Moses, you would believe me; for he wrote of me. But if you do not believe his writings, how will you believe my words? -
John 5:46-47
I wouldn't call what Jesus was doing "Parroting". Rather, I'd call it "quoting" and "teaching". Does a pastor "parrot" when he quotes scripture? No, he's just teaching the Word.
Mathew 26:64 has nothing to do with explicit details of creation.
Luke 3:21-22, the Holy spirit descended unto Him. This is all fine, but again, nothing to do with explicit details of creation.
Luke 4:1-4, so Jesus is stating that every man shall live by the word of God. Ok, great, still nothing to do with Jesus knowing explicit details of creation.
John 1, ok, Jesus has divine authority. I agree. Still nothing to do with Him knowing explicit details of creation.
It's quite simple. Jesus can speak of truth, while still having limitations in His awareness of past, present or future concepts and events.
There is a difference in the question of
If God created the universe and
How God created the universe. Jesus clearly indicates full awareness that in the beginning, God created. But there is no language in scripture that suggests that Jesus knew any exceptional details about how this unfolded. And while divine aspects of Jesus may be eternal, when Jesus came in human form to spread the gospel, with few exceptions, he relieved himself of things such as omniscience and omnipotence. He took on the form of man, limited in space and time as well.
Mathew 24:36 "But about that day or hour no one knows, not even the angels in heaven, nor the Son, but only the Father"
Some things Jesus simply didn't know. That doesn't make Jesus any less divine. While Jesus was divine, he was also fully man and experienced human limitations. Jesus was not infinitely powerful, he experienced pain just like us. Jesus needed to eat food because he would get hungry (Mark 11:12), and he would become tired (John 4:6). Jesus experienced human limitations. And limitations in omniscience is no exception. And scripture affirms this with these above verses, among others, and the simple absence of verses giving detailed accounts on OT events makes sense in light of this.
What you're doing is you're taking one or two vague verses, and extrapolating those verses to really extreme lengths. "God created the Universe, therefore Jesus knows molecular biology and astrophysics."
Nothing in scripture supports such a conclusion. And of course beyond that, it's still just more circular reasoning anyway to say "The bible says X and X is true because the Bible says so".
It's all the same. Extra-biblical conclusions made without scriptural support, and even worse, it's all encompassed in circular reasoning where the Bible proves the Bible proves the Bible without any external corroboration.
