Protestantism began as a protest against the edicts (decrees) of the Roman Church and called for freedom of conscience for all believers. The problem is that the protestants turned around and formed their own institutional church imposing their own rules and regulations.
Today all protestant denominations have their own institutional organization which sets the rules and regulations for member churches. They write and rewrite these rules as the leadership sees fit. It never seems to occur to them that in the church of the Bible, Christ is the only head and the law of Christ the only rule of faith and practice. There was no institutional authority over the individual congregations. All were subject only to Christ.
The churches of Christ are all autonomous (independent). We have no denominational or institutional structure. While there are thousands of individual churches of Christ throughout the world, we are all in conscience and organization free – subject only to Christ as the head and the law of Christ as our only rule of faith and practice.
