The church does not exist in its own right, nor it is to be regarded as other civil institutions or unions. It is not a club consisting of voluntary members. Neither is it self-determining. The church exists, both in its origins and prerogatives in and through Christ. Jesus Christ is the supreme head of the church. He tells Peter “On this rock I will build my church” (Matt 16:18
). It is his own personal possession. The church thus exists and is run according to the will and rule of Christ. Not one single member of the church of Christ exists outside of this authority. Every aspect of church life, including membership and worship, takes place under the authority of Christ.
