If the hypostatic union worked in the way you seem to think it does, Christ
could not have been crucified at all, because he basically would have been Superman. Recall the woman who was healed by touching the hem of his garment from Mark:
24 He went off with him, and a large crowd followed him and pressed upon him. There was a woman afflicted with hemorrhages for twelve years. 26 She had suffered greatly at the hands of many doctors and had spent all that she had. Yet she was not helped but only grew worse. 27 She had heard about Jesus and came up behind him in the crowd and touched his cloak. 28 She said, “If I but touch his clothes, I shall be cured.” 29 Immediately her flow of blood dried up. She felt in her body that she was healed of her affliction. 30* Jesus, aware at once that power had gone out from him, turned around in the crowd and asked, “Who has touched my clothes?” 31 But his disciples said to him, “You see how the crowd is pressing upon you, and yet you ask, ‘Who touched me?’” 32 And he looked around to see who had done it. 33 The woman, realizing what had happened to her, approached in fear and trembling***. She fell down before Jesus and told him the whole truth. 34 He said to her, “Daughter, your faith has saved you. Go in peace and be cured of your affliction.”
I think this makes it pretty clear that, in submission to the flesh, he cast off omniscience to a certain extent, willingly. If you deny this and say he was only acting to teach the disciples a lesson, I think you are in danger of embracing a form of
Docetism. Though, this does not surprise me - many people on this forum place so much emphasis on the more Puritanical elements of Christianity that they don’t even realize how dangerously close they tread to various Gnostic heresies.
The most important message I can give you is thins:
some elements of the Incarnation are a Mystery that cannot be fully explained using reason alone. I think the conscientiousness of Jesus is one of them. If is says in the Bible, Jesus tripped, assume he tripped. If it says, he asked who touched him, assume he meant it. Because, otherwise, I think that the way you are framing Jesus runs a very strong risk of denying his full humanity.
