Christ is the church's head
Paul states this plainly when writing about Jesus' supremacy. Christ is not simply an honoured founder or an inspiring example from the past. He is the living head of his people. In the Bible's picture, the church is his body, joined to him and dependent on him for its life and growth (Colossians 1:18; Ephesians 1:22-23).
That applies to the whole church, across places and generations, as well as to a local gathering of believers. A congregation may meet in a cathedral, a rented hall, or a home. Its true head is still Jesus.
And he is the head of the body, the church: who is the beginning, the firstborn from the dead; that in all things he might have the preeminence.
What being the head means
A head directs the body. So Christ has the final authority to define his people, shape their faith, and call them to obey him. The risen Jesus told his disciples that all authority had been given to him, then sent them out to make disciples and teach what he commanded (Matthew 28:18-20).
This means a church does not belong to its most persuasive speaker, oldest tradition, or most influential members. Those things can be valuable, but they must be tested by Christ's teaching in Scripture. When believers differ over practices, they can seek wisdom together while keeping Jesus at the centre.
And Jesus came and spake unto them, saying, All power is given unto me in heaven and in earth.
Leaders serve under Jesus
The New Testament does recognise pastors, teachers, elders, and other leaders. Christ gives such people to equip believers for ministry and to help the body mature (Ephesians 4:11-13). Their role matters. Healthy churches should not dismiss wise, faithful leadership.
Still, Christian leadership is never meant to replace Christ or control people for personal status. Peter urged elders to care for God's flock willingly and to lead by example rather than acting as masters over those entrusted to them (1 Peter 5:2-3). Jesus also warned his disciples against chasing religious titles and rank, because they were brothers under one Master (Matthew 23:8-10).
Living as Christ's body
If Jesus is the head, every believer has a place in his body. Paul used the image of many body parts to show that Christians need one another, even when their gifts and roles differ (1 Corinthians 12:12-14). No person is unneeded, and no leader is the whole body.
So a good question for any church is not merely, "Who is in charge here?" It is, "Are we listening to and following Christ?" Look for teaching that honours him, leadership that serves humbly, and a community growing in love and truth. Keep reading the Gospels for yourself, where Jesus' character and commands are most clearly seen.
And hath put all things under his feet, and gave him to be the head over all things to the church, Which is his body, the fulness of him that filleth all in all.
