Would you explain what you mean by 1?
“Jesus WAS in the form of God BEFORE He became a man, NOT after.“
What is the form of God?
Why is Jesus no longer in the form of God after he became a man?
What is the real ontological change?
Because the Bible says Jesus
came down from heaven.
Because the Bible says Jesus
became flesh.
Because the Bible says Jesus
became poor.
Because the Bible says Jesus
emptied himself.
Because the Bible says Jesus
shared, past tense, glory with the Father.
And many, many more descriptions of
change.
And on and on.... now what people do who say Jesus retained ALL of his divine attributes and merely ADDED (not subtracted—that's important), a NON-PERSONAL human nature ASSOCIATED with his divine person that thereby "counted" as an incarnation, what they do is say that all the above don't really mean what they say in any sense that correlates to our normal understanding of the terms—Jesus did not "leave" anything, he did not "become" anything, he did not "empty" anything, he did not have a past tense "sharing" of anything, because if Jesus has the entire Divine Nature along with the incarnation, Jesus is not poor, Jesus is in no sense empty, Jesus is currently fully sharing all glory, Jesus is currently entirely in heaven, Jesus did not "give up" anything whatsoever, Jesus just had a human nature "tacked on" and "associated" with him.
If I believe
the Word became flesh and dwelt among us, I can't then deny the Word is the real Person of Christ and had no actual change to his Person. What that change is, is granted to be the most mysterious thing in all of existence—but the Divine Nature of Christ must have been in some way altered (without being eliminated, he is still God), for him to have a legitimate human experience.
Peace.
