V. Our [58]Lord has most solemnly declared, and S. Paul repeated, that no one shall be saved without maintaining the true and uncorrupt faith. Of this Peter's faith is the standard and exemplar. Accordingly by the law of Christ unity with the faith of Peter is necessary to salvation. This law our Lord set forth in the words, "Confirm thy brethren." And to this the Fathers in their expressions above quoted allude. VI. The true faith and the true Church are so indivisibly united, that they cannot even be conceived apart from each other, faith being to the Church as light to the sun. But the true faith neither is, nor can be, other than that which Peter, "the first disciple of God," "the teacher of the world," "the mouthpiece of the disciples," and "the confirmer of his brethren," holds and proposes to others. No communion, therefore, called after Christ, which yet differs from that faith, can claim either the name or dignity of the true Church. VII. If any knowledge have a special value, it is surely that by which we have a safe and ready test of the true faith and the true Church. It is of the utmost necessity to know and embrace both, and the means of reaching them are proportionably valuable. Now that test abides in Peter, by keeping which before us we can neither miss the true faith nor the true Church. For no other true faith can there be than that which he delivers, who received the charge of confirming his brethren, nor other true Church than what Christ built, and is building still. Hence the expression of S. Ambrose,[59] "where Peter is, there is the Church;" and of Stephen[60] of Larissa, to Pope Boniface II. (A.D. 530.) "that all the churches of the world rest in the confession of Peter." VIII. With all these agrees that famous and most early testimony of S. Cyprian,[61] that men "fall away from the Church into heresy and schism so long as there is no regard _to the source of truth, no looking to the head_, nor keeping to the doctrine of our heavenly Master. If any one consider and weigh this, he will not need length of comment or argument. It is easy to offer proofs to a faithful mind, because in that case the truth may be quickly stated." And then he quotes our Lord's words to Peter, Matt. xvi. 16, and John xxi. 17, adding, "upon him being one He builds His Church." Therefore that Church can neither be torn from the one on whom she is built, nor profess any other faith, save what that one, who is Peter, proposes. FOOTNOTES: [1] Passaglia, p. 68. [2] Eph. i. 10.
