That Jesus is the legitimate head of the church all Bible students will admit (Ephesians 1:22-23; Colossians 1:18) and yet most churches are organized under some earthly ecclesiastical head.
Such was not the case originally. At first while each local congregation had its own internal organization of elders and deacons, no denominational organization existed. But over the centuries numerous denominations have developed exercising varying degrees of authority over local churches.
This was not true in original Christianity. Rather each local church was autonomous with Christ as its head and the apostles’ doctrine the only rule of faith and practice.
While we often benefit from the insights gleaned from the world of religious books, the Bible itself is the only real standard of religious thought and practice. All else is to be measured by it.
All theological opinions of men, all human traditions passed down to us from our forefathers, and all cultural trends of modern society are irrelevant.
No one is bound by any man-made confession of faith, manual of church order, or book of church discipline. The Bible alone must govern our faith and practice.
Christ himself is the Christian’s creed or more fully stated – “Thou art the Christ, the Son of the living God.” (Matthew 16:16) This is the original creed of Christianity. It is this that the first Christians believed, confessed and lived by.
All man-made creeds, theological opinions, commands of men, and human traditions are irrelevant at best and often worse. No man is required to subscribe to any theological system devised by men.
What is required is faith that Jesus is the Christ, the Son of the living God and obedience to Him as Lord and King. It is the belief of this fact and the obedience it implies that is the very foundation of Christianity. (Matthew 16:18)
