1 Corinthians 13:2

Every one that teaches anything beyond what is commanded, though he be [deemed] worthy of credit, though he be in the habit of fasting, though he live in continence, though he work miracles, though he have the gift of prophecy, let him be in thy sight as a wolf in sheep’s clothing, labouring for the destruction of the sheep. If any one denies the cross, and is ashamed of the passion, let him be to thee as the adversary himself. “Though he gives all his goods to feed the poor, though he remove mountains, though he give his body to be burned,” let him be regarded by thee as abominable. If any one makes light of the law or the prophets, which Christ fulfilled at His coming, let him be to thee as antichrist. If any one says that the Lord is a mere man, he is a Jew, a murderer of Christ.

2. But that this is the first and greatest commandment, and that the next [has respect to love] towards our neighbour, the Lord has taught, when He says that the entire law and the prophets hang upon these two commandments. Moreover, He did not Himself bring down [from heaven] any other commandment greater than this one, but renewed this very same one to His disciples, when He enjoined them to love God with all their heart, and others as themselves. But if He had descended from another Father, He never would have made use of the first and greatest commandment of the law; but He would undoubtedly have endeavoured by all means to bring down a greater one than this from the perfect Father, so as not to make use of that which had been given by the God of the law. …

For, in fine, the agreement and harmony of the faith of both contribute to one end, salvation. We have in the apostle an unerring witness: “For I desire to see you, that I may impart unto you some spiritual gift, in order that ye may be strengthened; that is, that I may be comforted in you, by the mutual faith of you and me.” And further on again he adds, “The righteousness of God is revealed from faith to faith.” The apostle, then, manifestly announces a twofold faith, or rather one which admits of growth and perfection; for the common faith lies beneath as a foundation. To those, therefore, who desire to be healed, and are moved by faith, He added, “Thy faith hath saved thee.” But that which is excellently built upon is consummated in the believer, and is again perfected by the faith which results from instruction and the word, in order to the performance of the commandments. …

14. Even if such men were slain in confession of the Name, that stain is not even washed away by blood: the inexpiable and grave fault of discord is not even purged by suffering. He cannot be a martyr who is not in the Church; he cannot attain unto the kingdom who forsakes that which shall reign there. Christ gave us peace; He bade us be in agreement, and of one mind. He charged the bonds of love and charity to be kept uncorrupted and inviolate; he cannot show himself a martyr who has not maintained brotherly love. Paul the apostle teaches this, and testifies, saying, “And though I have faith, so that I can remove mountains, and have not charity, I am nothing. And though I give all my goods to feed the poor, and though I give my body to be burned, and have not charity, it profiteth me nothing. …

In Malachi: “Hath not one God created us? Is there not one Father of us all? Why have ye certainly deserted every one his brother?” Of this same thing according to John: “Peace I leave with you, my peace I give unto you.” Also in the same place: “This is my commandment, That ye love one another, even as I have loved you. Greater love than this has no man, than that one should lay down his life for his friends.” Also in the same place: “Blessed are the peacemakers, for they shall be called the sons of God.” Also in the same place: “Verily I say unto you, That if two of you shall agree on earth concerning everything, whatever you shall ask it shall be given you from my Father which is in heaven. …

Now the father of the epileptic, perhaps the angel to whom he had been allotted, if we are to say that every human soul is put in subjection to some angel, prays the Physician of souls for his son that He may heal him who could not be healed from his disorder by the inferior word which was in the disciples. But the dumb and deaf spirit, who was cast out by the Word, must be figuratively understood as the irrational impulses, even towards that which seems to be good, so that, what things any man once did by irrational impulse which seemed to onlookers to be good, he may do no longer irrationally but according to the reason of the teaching of Jesus. …

But when the Saviour said, “ O faithfulness and perverse generation, ” He signifies that wickedness, which is contrary to nature, stealthily enters in from perversity, and makes us perverted. But of the whole race of men on earth, I think, being oppressed by reason of their wickedness and His tarrying with them, the Saviour said, “How long shall I be with you?” We have already, then, spoken in part of the words, “If ye have faith as a grain of mustard seed, ye shall say unto this mountain,” etc.; but nevertheless also we shall speak in this place the things that appear to us fitted to increase perspicuity. The mountains here spoken of, in my opinion, are the hostile powers that have their being in a flood of great wickedness, such as are settled down, so to speak, in some souls of men. …

32. There is no gift of God more excellent than this. It alone distinguishes the sons of the eternal kingdom and the sons of eternal perdition. Other gifts, too, are given by the Holy Spirit; but without love they profit nothing. Unless, therefore, the Holy Spirit is so far imparted to each, as to make him one who loves God and his neighbor, he is not removed from the left hand to the right. Nor is the Spirit specially called the Gift, unless on account of love. …

Chapter 8. 10. Nor indeed were the prayers of the Gentile Cornelius unheard, nor did his alms lack acceptance; nay, he was found worthy that an angel should be sent to him, and that he should behold the messenger, through whom he might assuredly have learned everything that was necessary, without requiring that any man should come to him. But since all the good that he had in his prayers and alms could not benefit him unless he were incorporated in the Church by the bond of Christian brotherhood and peace, he was ordered to send to Peter, and through him learned Christ; and, being also baptized by his orders, he was joined by the tie of communion to the fellowship of Christians, to which before he was bound only by the likeness of good works. And indeed it would have been most fatal to despise what he did not yet possess, vaunting himself in what he had. …

Chapter 9. 12. Let them see how many things, and what important things, are of no avail, if a certain single thing be wanting, and let them see what that one thing is. And herein let them hear not my words, but those of the apostle: "Though I speak with the tongues of men and of angels, and have not charity, I am become as sounding brass, or a tinkling cymbal. And though I have the gift of prophecy, and understand all mysteries, and all knowledge; and though I have all faith, so that I could remove mountains, and have not charity, I am nothing." What does it profit them, therefore, if they have both the voice of angels in the sacred mysteries, and the gift of prophecy, as had Caiaphas and Saul, that so they may be found prophesying, of whom Holy Scripture testifies that they were worthy of condemnation? If they not only know, but even possess the sacraments, as Simon Magus did; if they h …

Chapter 16. 21. But when it is said that "the Holy Spirit is given by the imposition of hands in the Catholic Church only, I suppose that our ancestors meant that we should understand thereby what the apostle says, "Because the love of God is shed abroad in our hearts by the Holy Ghost which is given unto us." For this is that very love which is wanting in all who are cut off from the communion of the Catholic Church; and for lack of this, "though they speak with the tongues of men and of angels, though they understand all mysteries and all knowledge, and though they have the gift of prophecy, and all faith, so that they could remove mountains, and though they bestow all their goods to feed the poor, and though they give their bodies to be burned, it profiteth them nothing." But those are wanting in God’s love who do not care for the unity of the Church; and consequently we are right in …

102. But the safe course for us is, not to advance with any rashness of judgment in setting forth a view which has neither been started in any regionary Council of the Catholic Church nor established in a plenary one; but to assert, with all the confidence of a voice that cannot be gainsaid, what has been confirmed by the consent of the universal Church, under the direction of our Lord God and Saviour Jesus Christ. Nevertheless, if any one were to press me, supposing I were duly seated in a Council in which a question were raised on points like these, to declare what my own opinion was, without reference to the previously expressed views of others, whose judgment I would rather follow, if I were under the influence of the same feelings as led me to assert what I have said before, I should have no hesitation in saying that all men possess baptism who have received it in any place, from an …
