Section 1 means that the Roman church received the primacy over the whole church directly from Christ. Section 8 is based on the forged Donation of Constantine, according to which the emperor gave the pope the right to use the imperial insignia. In section 11 it is not clear what name is meant. It may be "universal" as in section 2. The bishop of Rome claimed the exclusive right to call himself pope, apostolic, and universal. Papa or pope was at first the common title of all priests, and is still so in the Greek church. But in the course of time it was limited in the west to the bishop of Rome. "Apostolic" was at first applied to all bishops, but eventually the bishop of Rome claimed the exclusive right to it and forbade all other bishops to use it. Since the bishop of Rome was the head of the whole church he was the only one who could call himself "universal." The right of ordaining, section 14, that is, of raising to the clerical rank, belonged to each bishop, but he could exercise it only in his own diocese. But the bishop of Rome had the whole world for his diocese, and hence he could ordain any one, no matter to what bishopric he belonged. In explanation of section 23 the following passage from pope Symmachus (498-514) is offered (Hinschius, "Decretales," p. 666). "We do not judge that St. Peter received from the Lord with the prerogative of his chair [that is, with his primacy] the right to sin. But he passed on to his successors the perennial dower of his merits with his heritage of innocence. Who can doubt that he who is exalted to the height of apostolic dignity is holy?" 66. Letter of Gregory VII to all the Faithful, Commending his Legates, 1074. Migne, 148, col. 392. It had not been uncommon for the popes to send their legates on missions to various parts of the world, but Gregory VII made a far more frequent use of them than any of his predecessors. He practically ruled the church through them and demanded that they be received and obeyed by all. This letter shows his general attitude on the matter, the authority he gave them, and the reception which he expected them to have. Gregory, bishop, servant of the servants of God, to all the faithful subjects of St. Peter, to whom these presents come, greeting and apostolic benediction.
