And put all things under his feet; a strong, figurative expression, denoting high sovereignty. It does not refer merely to defeated and arrested enemies, but to the whole of creation and the fullness thereof.
They are as thoroughly under Christ and at his disposal as if they were literally under his feet. As a military commander, proceeding even through his own country, has power to requisition everything needful for his army, and deal with all property as may be required for military purposes, so Christ has the whole creation at his disposal, animate and inanimate, hostile and friendly.
And gave him to be Head over all things to the Church. The exaltation of Christ is not merely an honor conferred on himself, but has also a definite practical purpose; it is for the benefit of the Church.
God gave him to the Church as Head over all things. The gift of Christ to the Church is the gift of One who has sovereign authority over all things. The official subordination of Christ to the Father is recognized throughout this remarkable passage.
So in Philippians, though he was "in the form of God, and thought it not robbery to be equal with God, he made himself of no reputation, and took upon him the form of a servant, and was made in the likeness of men."
It is this Jesus, in the form of a servant and in the likeness of men, that is now Head over all things, and as such given by the Father to the Church. With such a Head, what need the Church fear, and what can she want?
