Perhaps, Ernest, I've been misunderstanding your views on objective morality all this time. Do you deny that God has free will, or do you deny omnibenevolence as a real concept?
Free will is incompatible with the combination of omnibenevolence and omniscience, since one who is both omniscient and omnibenevolent knows what is the best thing to do and will always do what he can to achieve it. Hence, God lacks free will. Jesus Christ during the time of his ministry had human characteristics and that included free will. If he had not had free will, then his temptation in the wilderness and later would have been a sham and a mockery.
I hold to an Adoptionist viewpoint on the nature of Jesus Christ. My current best understanding of the ministry of Jesus has him receiving the triple aspects of the Godhead at different stages. Upon being baptized he received the omnipotence of God becoming Jesus Christ. His crucifixion was the capstone of His acquisition of the omnibenevolence of God, tho one can argue whether he received it at Gethsemane or later. It was only at his resurrection that he received the omniscience of God and the full authority to act as God in his own right by his possession of the full triune Godhead.
Also my views on omniscience, omnipotence, and omnibenevolence are that they are not unlimited. God possesses all the knowledge, ability, and love it is possible to have, yet there are things that are beyond even God.
