Священство
Apostolic succession is the belief that the pope and Catholic bishops are the spiritual successors of the original twelve apostles, through the historically unbroken chain of consecration (see: Holy orders). The pope is the spiritual head and leader of the Catholic Church who makes use of the Roman Curia to assist him in governing. He is elected by the College of Cardinals who may choose from any male member of the church but who must be ordained a bishop before taking office. Since the 15th century, a current cardinal has always been elected.
