We are fully convinced that the disciples of the first century were not members of different denominations, but were united in one body, practicing one faith, under one authority–the one Lord (Ephesians 4:4-6). To belong only to Christ is something altogether different from belonging to just any one of the over 400 religious bodies in our country (see Matthew 15:6-13).
We urge all to join in being diligent to preserve the unity of the Spirit (Ephesians 4:3-6). The only way we can answer Christ’s prayer for unity (John 17:20-21) is to let the Bible be our only guide. We do not claim to be infallible in this, and therefore welcome anyone who can teach us the way of God more perfectly (Acts 18:25-26). But we do believe that God’s word is truth, therefore infallible, and consequently it does matter what one believes. We strive to speak where the Bible speaks and remain silent where the Bible is silent. If we would all do this, all human traditions, sectarian names, creeds, and organizations would be set aside and Christ would be glorified.
The church that Jesus built is the manifestation of God’s wisdom, not man’s (Ephesians 3:10-11), and He is its only head (Ephesians 1:22-23; 3:15). Therefore, His church is not dependent for its external existence on the succession of an order of preachers or popes, neither is it dependent on synods, councils, mosques, conventions, and/or denominational headquarters. Jesus said that the life principle of His kingdom is in His word, the seed of the kingdom (Luke 8:11; 1 Peter 1:22-23). In any place and at any time that men let their hearts be led by the word of God, the church of Jesus Christ will flourish.
And when they had appointed elders for them in every church, with prayer and fasting they committed them to the Lord in whom they had believed. Acts 14:23
And let them also be tested first; then let them serve as deacons if they prove themselves blameless. 1 Timothy 3:10
