The church of Christ is just that. It is not a name but a description. We are literally Christ’s church. In Matthew 16:18, Jesus said that he will build His church. Christ only built one church. The word church is a deceiving term, it literally means the “called-out” or the “assembly”, so therefore we are the assembly of Christ. The ones who have entered into the body of Christ, make up the church. The church is not a building but the people who make up the assembly. We are a local autonomous assembly that is overseen by the Elders of the congregation. We are a part of the entire body of Christ but each congregation is autonomous and is not governed by any headquarters but Christ as being the head of the church (Ephesians 1:22).
The Bible is our sole authority. We speak where the Bible speaks and are silent where the Bible is silent. Anything we do as an expedient we do not do in opposition to the Lord’s will. In Ephesians 4:11-16, we see the basic plan for the church. As a whole and individually we are to grow in to all aspects of Christ; into a mature Christian. We as individuals not only help ourselves but encourage each other to grow into Christ-likeness so that the body will be built up in love.
Our goal is not just to convert people to Christ and be done but to bring people closer to God by becoming Christ like. So this means that the Christian life does not stop at entering into the body at baptism (Acts 2:42; Galatians 3:27; 1 Peter 3:20-21). Romans 6:3-7, shows us that in baptism we walk a new life so that our body of sin may be done away with. The body of Christ walks in the light as He is in the light (1 John 1:7). The Christian lifestyle brings both hope and security that if one remains faithful until death he/she will receive the crown of righteousness (Hebrews 6:19, 20; Revelation 2:20; James 1:12).
To sum it up: 28 We proclaim Him, admonishing every man and teaching every man with all wisdom, so that we may present every man complete in Christ. 29 For this purpose also I labor, striving according to His power, which mightily works within me. (Col. 1:28-29)
