The CHURCH that the bible refers to never had added identification attached to it to distinguish one denomination from another. In fact, the bible clearly indicates that doing so is wrong (see 1 Cor 3 - entire chapter).
The CHURCH is not the Catholic Church, the Presbyterian Church, the Episcopalian Church, the Anglican Church, the Baptist Church, etc.
The CHURCH found in the New Testament, had no hierachy; each church was independent of control by other local churches. Each church was to be under the oversight of men who were members of that local church, not controlled by some council from great distances.
As individuals were added to the CHURCH, they were part of the total membership of the family of God, through their acceptance of Christ, and worshipped and participated in good works at the local level; there was no hierarchy or governing body other than the local church. When famine hit other parts of the world, and Apostles called for local churches to send aid to the Christians in other areas, that aid was turned over to the local church for distribution. One church from afar did not set up a missionary society to oversee the distribution of it's disaster relief in the area of the local church that was suffering.
The fact that there exists so many different religious identifications today, is evidence that people are discontent to follow the word of God; they have to add thier own "flavor" to the word that God provided us through Jesus the Christ. God warns his people not to Add To or to Take Away From his word; those that do so will be judged.
Religious denominations are at odds with what God commands from his followers. God did not create many different churches with different doctrines; God created ONE CHURCH, the church that God possesses, the church that Christ rules. The CHURCH of God, the CHURCH of Christ is the church of the new testament; only God and Christ can possess and be the head of that church, which is the Bride of Christ, and Christ is the head of the church, the body being the individual members of that church.
The so called church history is actually the history of the departure from the teaching of Christ, and the creation of hierarchies that God never intended for his people. The history of protestantism, with the split from the Catholic Church by people following the teachings of Martin Luther and others, is not a history of the church that God created; it is a history of churches that MAN created, because man was not content to follow the rule of God and Christ.
If you want to understand what God and Christ intended their worshippers to do, then throw away the creeds and catechisms, the later day revelations, and ignore the false prophets of modern times; go back to the Bible for the only real authority, and use a sound translation of the scripture, instead of a paraphrased interpretation published by biased and fallible men.
