You are mistaken in your conclusion here. I never said, deduced or even inferred that the Father 'took on' any human form. That's going way to far..You both think that the Father took on human form, and that he did so at "his baptism"?
Joh 1:14 And the Word became flesh and dwelt among us, and we have seen his glory, glory as of the only Son from the Father, full of grace and truth.
Php 2:5 Have this mind among yourselves, which is yours in Christ Jesus,
Php 2:6 who, though he was in the form of God, did not count equality with God a thing to be grasped,
Php 2:7 but emptied himself, by taking the form of a servant, being born in the likeness of men.
Php 2:8 And being found in human form, he humbled himself by becoming obedient to the point of death, even death on a cross.
How does answer "c" take those passages into account?
Need to pay more attention.
Let me spell it out once more. Yeshua the man, the 2nd Adam, not born to sin as in corrupted man, still required his Father's spirit to be present within his own spirit to perform his mission successfully. It would have been impossible for Yeshua to complete his mission successfully to the Cross otherwise. Yeshua, the Son, needed his fathers' word and his enhanced. empowering spirit embedded within him to succeed. They were AS (still separate spirits) one spirit and worked and walked to the Cross together.
Now does that sound like any transformation of the Father, who is the only God. Not at all! It was the Son who was transformed from within as the man chosen by God. There is the a true description or version and definition of Yeshua's anointing - the Messiah of God.
