4. If any one consider and examine these things, there is no need for lengthened discussion and arguments. There is easy proof for faith in a short summary of the truth. The Lord speaks to Peter,10 [On the falsifying of the text by Romish editors, see Elucidation II.] saying, “I say unto thee, that thou art Peter; and upon this rock I will build my Church, and the gates of hell shall not prevail against it. And I will give unto thee the keys of the kingdom of heaven; and whatsoever thou shalt bind on earth shall be bound also in heaven, and whatsoever thou shalt loose on earth shall be loosed in heaven.”11 Matt. xvi. 18, 19. And again to the same He says, after His resurrection, “Feed my sheep.”12 John xxi. 15. [Here is interpolated]: “Upon him, being one, He builds His Church, and commits His sheep to be fed.” And although to all the apostles, after His resurrection, He gives an equal power, and says, “As the Father hath sent me, even so send I you: Receive ye the Holy Ghost: Whose soever sins ye remit, they shall be remitted unto him; and whose soever sins ye retain, they shall be retained;”13 John xx. 21. yet, that He might set forth unity, He arranged by His authority the origin of that unity, as beginning from one. Assuredly the rest of the apostles were also the same as was Peter, endowed with a like partnership both of honour and power; but the beginning proceeds from unity.14 [Here is interpolated]: “And the primacy is given to Peter, that there might be shown one Church of Christ and one See; and they are all shepherds, and the Rock is one, which is fed by all the apostles with unanimous consent.” This passage, as well as the one a few lines before, is beyond all question spurious. Which one Church, also, the Holy Spirit in the Song of Songs designated in the person of our Lord, and says, “My dove, my spotless one, is but one. She is the only one of her mother, elect of her that bare her.”15 Cant. vi. 9. Does he who does not hold this unity of the Church think that he holds the faith? Does he who strives against and resists the Church16 [Here is interpolated]: “Who deserts the chair of Peter, upon whom the Church is founded.” This passage also is undoubtedly spurious. trust that he is in the Church, when moreover the blessed Apostle Paul teaches the same thing, and sets forth the sacrament of unity, saying, “There is one body and one spirit, one hope of your calling, one Lord, one faith, one baptism, one God?”17 Eph. iv. 4.
IV. Quae si quis consideret et examinet, tractatu longo atque argumentis opus non est. Probatio est ad fidem facilis compendio veritatis. Loquitur Dominus ad Petrum: Ego tibi dico, inquit, quia tu es Petrus, et 0499A super hanc petram aedificabo Ecclesiam meam, et portae inferorum non vincent eam. Et tibi dabo claves regni coelorum: et quae ligaveris super terram, erunt ligata et in coelis; et quaecumque solveris super terram, erunt soluta et in coelis (Matth. XVI, 18, 19). Et iterum eidem post resurrectionem suam dicit: Pasce oves meas (Joan. XXI, 15). Super illum unum aedificat Ecclesiam suam, et illi pascendas mandat oves suas . Et quamvis Apostolis omnibus post resurrectionem suam parem potestatem tribuat et dicat, Sicut misit me Pater, et ego mitto vos: accipite Spiritum sanctum; si cujus remiseritis peccata, remittentur illi, si cujus tenueritis, tenebuntur (Joan. XX, 21-23), tamen, ut unitatem manifestaret, unam cathedram constituit , unitatis ejusdem originem ab uno incipientem 0500A sua auctoritate disposuit. Hoc erant utique et caeteri Apostoli quod fuit Petrus , pari consortio praediti et honoris et potestatis, sed exordium ab unitate proficiscitur , et primatus Petro datur , ut una Christi Ecclesia et cathedra una monstretur . Et pastores sunt omnes, et grex unus ostenditur, qui ab Apostolis omnibus unanimi consensione pascatur, ut Ecclesia Christi una monstretur. Quam unam Ecclesiam etiam in Cantico canticorum Spiritus sanctus ex persona Domini designat et dicit: Una est columba mea, perfecta mea, una est matri suae, electa genitrici suae (Cant. VI, 9). Hanc Ecclesiae unitiatem qui non tenet, tenere se fidem credit? Qui Ecclesiae renititur et resistit, qui cathedram Petri, super quem fundata est Ecclesia, deserit , in Ecclesia se 0501A esse confidit? quando et beatus apostolus Paulus hoc idem doceat et sacramentum unitatis ostendat dicens: Unum corpus et unus spiritus, una spes vocationis vestrae, unus Dominus, una fides, unum Baptisma, unus Deus (Ephes. IV, 4-6).
