Why do Christians reject Jesus is God in the flesh? They have good reasons, MANY good reasons. For instance, consider Christianity's end game. NOTE: Who is not to be put under the feet of the Anointed? Not 'the Father.' God, in his unitarian nature. If Jesus were God, even part of a trinitarian God, this distinction would not be necessary.
'The Father' alone is God. The Bible says this over and over and over again. The Bible never says God, the Son. What part of this do you not grasp?
23 But this is how it will happen: the Anointed’s awakening is the firstfruits. It will be followed by the resurrection of all those who belong to Him at His coming, 24 and then the end will come. After He has conquered His enemies and shut down every rule and authority vying for power, He will hand over the Kingdom to God, the Father of all that is. 25 And He must reign as King until He has put all His enemies under His feet. 26 The last hostile power to be destroyed is death itself. 27 All this will happen to fulfill the Scripture that says, “You placed everything on earth beneath His feet.” (Although it says “everything,” it is clear that this does not also pertain to God, who created everything and made it all subject to Him.) 28 Then, when all creation has taken its rightful place beneath God’s sovereign reign, the Son will follow, subject to the Father who exalted Him over all created things; then God will be God over all.
