Satis Cognitum §13

¹³ It was necessary that a government of this kind, since it belongs to the constitution and formation of the Church, as its principal element - that is as the principle of unity and the foundation of lasting stability - should in no wise come to an end with St. Peter, but should pass to his successors from one to another. "There remains, therefore, the ordinance of truth, and St. Peter, persevering in the strength of the rock which he had received, hath not abandoned the government of the Church which had been confided to him" (S. Leo M. sermo iii., cap. 3). For this reason the Pontiffs who succeed Peter in the Roman Episcopate receive the supreme power in the church, jure divino . "We define" (declare the Fathers of the Council of Florence) "that the Holy and Apostolic See and the Roman Pontiff hold the primacy of the Church throughout the whole world: and that the same Roman Pontiff is the successor of St. Peter, the Prince of the Apostles, and the true Vicar of Christ, the head of the whole Church, and the father and teacher of all Christians; and that full power was given to him, in Blessed Peter, by our Lord Jesus Christ to feed, to rule, and to govern the universal Church, as is also contained in the acts of oecumenical councils and in the sacred canons" ( Conc. Florentinum ). Similarly the Fourth Council of Lateran declares: "The Roman Church, as the mother and mistress of all the faithful, by the will of Christ obtains primacy of jurisdiction over all other Churches." These declarations were preceded by the consent of antiquity which ever acknowledged, without the slightest doubt or hesitation, the Bishops of Rome, and revered them, as the legitimate successors of St. Peter. Who is unaware of the many and evident testimonies of the holy Fathers which exist to this effect? Most remarkable is that of St. Irenaeus who, referring to the Roman Church, says: "With this Church, on account of its preeminent authority, it is necessary that every Church should be in concord" ( Contra Haereses , lib. iii., cap. 3, n. 2); and St. Cyprian also says of the Roman Church, that "it is the root and mother of the Catholic Church, the chair of Peter, and the principal Church whence sacerdotal unity has its source" (Ep. xlviii., ad Cornelium , n. 3. and Ep. liac., ad eundem, n. 14). He calls it the chair of Peter because it is occupied by the successor of Peter: he calls it the principal Church, on account of the primacy conferred on Peter himself and his legitimate successors; and the source of unity , because the Roman Church is the efficient cause of unity in the Christian commonwealth. For this reason Jerome addresses Damasus thus: "My words are spoken to the successor of the Fisherman, to the disciple of the Cross....I communicate with none save your Blessedness, that is with the chair of Peter. For this I know is the rock on which the Church is built" (Ep. xv., ad Damasum , n. 2). Union with the Roman See of Peter is to him always the public criterion of a Catholic. "I acknowledge everyone who is united with the See of Peter" (Ep. xvi., ad Damasum, n. 2). And for a like reason St. Augustine publicly attests that, "the primacy of the Apostolic chair always existed in the Roman Church" (Ep. xliii., n. 7); and he denies that anyone who dissents from the Roman faith can be a Catholic. "You are not to be looked upon as holding the true Catholic faith if you do not teach that the faith of Rome is to be held" (Sermo cxx., n. 13). So, too, St. Cyprian: "To be in communion with Cornelius is to be in communion with the Catholic Church" (Ep. lv., n. 1). In the same way Maximus the Abbot teaches that obedience to the Roman Pontiff is the proof of the true faith and of legitimate communion. Therefore if a man does not want to be, or to be called, a heretic, let him not strive to please this or that man...but let him hasten before all things to be in communion with the Roman See. If he be in communion with it, he should be acknowledged by all and everywhere as faithful and orthodox. He speaks in vain who tries to persuade me of the orthodoxy of those who, like himself, refuse obedience to his Holiness the Pope of the most holy Church of Rome: that is to the Apostolic See." The reason and motive of this he explains to be that "the Apostolic See has received and hath government, authority, and power of binding and loosing from the Incarnate Word Himself; and, according to all holy synods, sacred canons and decrees, in all things and through all things, in respect of all the holy churches of God throughout the whole world, since the Word in Heaven who rules the Heavenly powers binds and loosens there" ( Defloratio ex Epistola ad Petrum illustrem ). Wherefore what was acknowledged and observed as Christian faith, not by one nation only nor in one age, but by the East and by the West, and through all ages, this Philip, the priest, the Pontifical legate at the Council of Ephesus, no voice being raised in dissent, recalls: "No one can doubt, yea, it is known unto all ages, that St. Peter, the Prince of the Apostles, the pillar of the faith and the ground of the Catholic Church, received the keys of the Kingdom from Our Lord Jesus Christ. That is: the power of forgiving and retaining sins was given to him who, up to the present time, lives and exercises judgment in the persons of his successors" (Actio iii.). The pronouncement of the Council of Chalcedon on the same matter is present to the minds of all: "Peter has spoken through Leo" (Actio ii.), to which the voice of the Third Council of Constantinople responds as an echo: "The chief Prince of the Apostles was fighting on our side: for we have had as our ally his follower and the successor to his see: and the paper and the ink were seen, and Peter spoke through Agatho" (Actio xviii.). In the formula of Catholic faith drawn up and proposed by Hormisdas, which was subscribed at the beginning of the sixth century in the great Eighth Council by the Emperor Justinian, by Epiphanius, John and Menna, the Patriarchs, this same is declared with great weight and solemnity. "For the pronouncement of Our Lord Jesus Christ saying: ' Thou art Peter, and upon this rock I will build my Church ,' &c., cannot be passed over. What is said is proved by the result, because Catholic faith has always been preserved without stain in the Apostolic See" (Post Epistolam, xxvi., ad omnes Episc. Hispan., n. 4). We have no wish to quote every available declaration; but it is well to recall the formula of faith which Michael Paleologus professed in the Second Council of Lyons: "The same holy Roman Church possesses the sovereign and plenary primacy and authority over the whole Catholic Church, which, truly and humbly, it acknowledges to have received together with the plenitude of power from the Lord Himself, in the person of St. Peter, the Prince or Head of the Apostles, of whom the Roman Pontiff is the successor. And as it is bound to defend the truth of faith beyond all others, so also if any question should arise concerning the faith it must be determined by its judgment" ( Actin iv.).
