Is Jesus Head of the Church?

In the natural realm, a head must be connected to a body or both are useless and neither functions. In the spiritual realm of Christianity, things are different. We have a Head in heaven, Jesus, and a body on earth, the whole Christian company throughout the world. It is by the person of the Holy Spirit that the Head in heaven is linked with His body on earth. In Colossians, the author considers the greatness of the person of Jesus Christ as the one who is the Head of the Church. His greatness is known because, as "the image of the invisible God", He represents God and makes God known. The impact for the Church is that we should make God known: as the body is to give expression to, and is controlled by, the Head. In Ephesians and 1st Corinthians, Paul shows that the truth of Christ as Head of the Church also has very practical lessons for Christians in husband/wife relationships. Lastly, the author touches upon a related topic of Christ as the head stone of the corner. Here the teaching likens the Christian company to a building. As a building is constructed it has a fixed reference point, the reference point is Christ as the Chief corner stone.
However, at the same time, when the building is considered as a complete structure He is the head stone of the corner - the stone that is given prominence in the structure as the crowning glory to the building.
