'Head' in the Bible

with regard to the fulfillment of the times [that is, the end of history, the climax of the ages]—to bring all things together in Christ, [both] things in the heavens and things on the earth.

And He put all things [in every realm] in subjection under Christ’s feet, and appointed Him as [supreme and authoritative] head over all things in the church,

But speaking the truth in love [in all things—both our speech and our lives expressing His truth], let us grow up in all things into Him [following His example] who is the Head—Christ.

For the husband is head of the wife, as Christ is head of the church, Himself being the Savior of the body.
