had been prepared, that of a monk named Gratian, compiled in the twelfth century, was the most widely used. [Sidenote: The Pope and his Powers] We are now in a position to summarize the claims and prerogatives of the bishop of Rome or pope. (1) He was the supreme lawgiver. He could issue decrees of his own, which might not be set aside by any other person. No council might enact canons without his approval. From any law, other than divine, he might dispense persons. (2) He was the supreme judge in Christendom. He claimed that appeals might be taken from decisions in foreign courts to his own Curia, as court of last resort. He himself frequently acted as arbitrator, as, for example, in the famous dispute between Spain and Portugal concerning the boundaries of their newly discovered possessions. (3) He was the supreme administrator. He claimed the right to supervise the general business of the whole Church. No archbishop might perform the functions of his office until he received his insignia--the pallium--from the pope. No bishop might be canonically installed until his election had been confirmed by the pope. The pope claimed the right to transfer a bishop from one diocese to another and to settle all disputed elections. He exercised immediate control over the regular clergy--the monks and nuns. He sent ambassadors, styled legates, to represent him at the various royal courts and to see that his instructions were obeyed. (4) He insisted upon certain temporal rights, as distinct from his directly religious prerogatives. He crowned the Holy Roman Emperor. He might depose an emperor or king and release a ruler's subjects from their oath of allegiance. He might declare null and void, and forbid the people to obey, a law of any state, if he thought it was injurious to the interests of the Church. He was temporal ruler of the city of Rome and the surrounding papal states, and over those territories he exercised a power similar to that of any duke or king. (5) He claimed financial powers. In order to defray the enormous expenses of his government, he charged fees for certain services at Rome, assessed the dioceses throughout the Catholic world, and levied a small tax--Peter's Pence--upon all Christian householders.
