The pope was not merely the supreme lawgiver; he was the supreme judge. As a distinguished legal writer has said, the whole of western Europe was subject to the jurisdiction of one tribunal of last resort, the pope's court at Rome. Any one, whether clergyman or layman, in any part of Europe, could appeal to him at any stage in the trial of a large class of cases. Obviously this system had serious drawbacks. Grave injustice might be done by carrying to Rome a case which ought to have been settled in Edinburgh or Cologne, where the facts were best known. The rich, moreover, always had the advantage, as they alone could afford to bring suits before so distant a court. [Sidenote: The control of the pope over the clergy at large.] The control of the pope over the clergy scattered throughout Christendom was secured in several ways. A newly elected archbishop might not venture to perform any of the duties of his office until he had taken an oath of fidelity and obedience to the pope and received from him the _pallium_, the archbishop's badge of office. This was a narrow woolen scarf made by the nuns of the convent of St. Agnes at Rome. Bishops and abbots were also required to have their election duly confirmed by the pope. He claimed, too, the right to settle the very frequent disputed elections of church officials. He might even set aside both of the rival candidates and fill the office himself, as did Innocent III when he forced the monks of Canterbury, after a double election, to choose Stephen Langton. Since the time of Gregory VII the pope had claimed the right to depose and transfer bishops at will. The control of Rome over all parts of the Christian Church was further increased by the legates. These papal emissaries were intrusted with great powers. Their haughty mien often enough offended the prelates and rulers to whom they brought home the authority of the pope,--as, for instance, when the legate Pandulf grandly absolved all the subjects of King John of England, before his very face, from their oath of fealty to him. [Sidenote: The Roman Curia.] The task assumed by the pope of governing the whole western world naturally made it necessary to create a large body of officials at Rome in order to transact all the multiform business and prepare and transmit the innumerable legal documents.[135] The cardinals and the pope's officials constituted what was called the papal Curia, or court.
