Leadership in the Catholic and Protestant Church

Leadership is an important aspect of all unified groups of people. In the case of the Church, leadership prevents schism and heresies from destroying the Church. The magisterium guided by the Holy Spirit prevents incorrect teaching from being spread. This means that heresies are corrected, and questions are answered. In the Protestant Church, there is no hierarchical structure similar the the Catholic Church. The clergy in the Protestant Church is ordained by the denomination, this means that there is not a unifying, ultimate person solving the problem. A person can go and split off from his or her denomination over a simple teaching and still be called Protestant.  This is partly the reason why there are 30,000 different Protestant churches, but only one Catholic Church.
