Dear TibiasDad
For centuries, no Jew ever understood that passage as meaning that the God of Abraham, Isaac and Jacob was going to be the Anointed [The Messiah]. Jesus presented Himself as a the Anointed. The apostles presented Him as The Anointed.
The Anointed is he who is anointed by God. Not God.
Paul explains the verse you are quoting, and makes clear that God is the one putting the enemies a footstool of Jesus feet, and subjects everyone to Christ. EXCEPT BY GOD HIMSELF. Paul then makes it clear that Christ will subject Himself to God.
Then comes the end, when he hands over the kingdom to God the Father, after he has destroyed every sovereignty and authority and power. For he is destined to reign until he has put all his enemies under his feet.
The last enemy to be destroyed is death. For he has put all things under his feet. But when it says “all things are put under,” it is obvious that this excludes the one who subjected everything to him. When all things are subjected to him, then the Son himself will also be subjected to the one who made all things subject to him, so that God may be all in all.
(1 Cor 15:24-28).
