What does the Bible say about the headship of Christ?

The New Testament presents the headship of Christ as paramount in understanding His authority and role in relation to the church. According to Ephesians 1:22-23, God has placed all things under Christ's feet and appointed Him to be the head over all things for the church. This establishes Christ as the sovereign ruler who exercises authority not only over spiritual realms, including angels and principalities, but also over the entire universe. As the head of the church, He is intimately connected to His body, the believers, signifying that what happens to the church is closely tied to His own authority and purpose. His headship is not merely a title but a vital and governing relationship that informs Christian doctrine and life.
