The church of Christ belongs to Christ. "Of Christ" denotes possession or ownership. It is not a proper name, for no name is given in the New Testament. The church which belongs to the Christ is the one He promised to build (see Matthew 16:18ff) and did build (Acts chapters one and two).

The church is from the Greek, ekklesia, and when translated is "the called out." Paul states that the one body (Ephesians 4) has as its head, Jesus Christ, and that the body is the church (Colossians 1:18 and Ephesians 1:22, 23).

There is only one body even as there is only one head, thus one church having one head as final and complete authority. Jesus built His church as the vehicle for saving the lost.

The church is the saved, for those saved are added to the church (Acts 2:47). And thus it should be for Jesus bought (purchased) the church with His own precious blood by the which blood "he washed us from our sins."
