I don’t know what it means to concelebrate a Mass in public with a confirmed dissident priest, nor why raising alarm at such a spectacle merits being keelhauled by fishers, but I believe the following words of papal counsel are more timely than ever.* I am as challenged by the pope here as I hope all sensible Catholics allow themselves to be.
7. … Never perhaps was there more talking about the brotherhood of men than there is today; in fact, men do not hesitate to proclaim that striving after brotherhood is one of the greatest gifts of modern civilization, ignoring the teaching of the Gospel, and setting aside the work of Christ and of His Church. But in reality never was there less brotherly activity amongst men than at the present moment. …
19. … Over and above those luminous proofs of the divine power and indefectibility enjoyed by the Church, We find a source of no small consolation in the remarkable fruits of the active foresight of our Predecessor, Pope Pius X, who shed upon the Apostolic Chair the lustre of a most holy life. For We see as a result of his efforts a revival of religious spirit in the clergy throughout the whole world; the piety of the Christian people revived; activity and discipline stimulated in Catholic associations; the foundation and increase of episcopal sees; provision made for the education of ecclesiastical students in harmony with the canonical requirements and in so far as necessary with the needs of the times; the saving of the teaching of sacred science from the dangers of rash innovations; musical art brought to minister worthily to the dignity of sacred functions; the Faith spread far and wide by new missions of heralds of the Gospel.
20. Well, indeed, has Our Predecessor merited of the Church, and grateful posterity will preserve the memory of his deeds. As, however, by God’s permission, the field of “the good man of the house” is ever exposed to the evil practices of “the enemy,” it will never come to pass that no work will be necessary to prevent the growth of “the cockle” from damaging the good harvest; and applying to ourselves God’s words to the prophet: “Lo, I have set thee this day over the nations and over kingdoms, to root up and to pull down . . . to build and to plant” (Jerem. i. 10), it will be Our constant and strenuous endeavour, as far as it is in Our power, to prevent evil of every kind and to promote whatever is good, until it shall please the Prince of Pastors to demand an account of Our discharge of Our office. …
22. The success of every society of men, for whatever purpose it is formed, is bound up with the harmony of the members in the interests of the common cause. Hence We must devote Our earnest endeavours to appease dissension and strife, of whatever character, amongst Catholics, and to prevent new dissensions arising, so that there may be unity of ideas and of action amongst all. The enemies of God and of the Church are perfectly well aware that any internal quarrel amongst Catholics is a real victory for them. Hence it is their usual practice when they see Catholics strongly united, to endeavour by cleverly sowing the seeds of discord, to break up that union. And would that the result had not frequently justified their hopes, to the great detriment of the interests of religion! Hence, therefore, whenever legitimate authority has once given a clear command, let no one transgress that command, because it does not happen to commend itself to him; but let each one subject his own opinion to the authority of him who is his superior, and obey him as a matter of conscience. Again, let no private individual, whether in books or in the press, or in public speeches, take upon himself the position of an authoritative teacher in the Church. All know to whom the teaching authority of the Church has been given by God: he, then, possesses a perfect right to speak as he wishes and when he thinks it opportune. The duty of others is to hearken to him reverently when he speaks and to carry out what he says.
23. As regards matters in which without harm to faith or discipline – in the absence of any authoritative intervention of the Apostolic See – there is room for divergent opinions, it is clearly the right of everyone to express and defend his own opinion. But in such discussions no expressions should be used which might constitute serious breaches of charity; let each one freely defend his own opinion, but let it be done with due moderation, so that no one should consider himself entitled to affix on those who merely do not agree with his ideas the stigma of disloyalty to faith or to discipline.
24. It is, moreover, Our will that Catholics should abstain from certain appellations which have recently been brought into use to distinguish one group of Catholics from another. They are to be avoided not only as “profane novelties of words,” out of harmony with both truth and justice, but also because they give rise to great trouble and confusion among Catholics. Such is the nature of Catholicism that it does not admit of more or less, but must be held as a whole or as a whole rejected: “This is the Catholic faith, which unless a man believe faithfully and firmly; he cannot be saved” (Athanas. Creed). There is no need of adding any qualifying terms to the profession of Catholicism: it is quite enough for each one to proclaim “Christian is my name and Catholic my surname,” only let him endeavour to be in reality what he calls himself.
25. Besides, the Church demands from those who have devoted themselves to furthering her interests, something very different from the dwelling upon profitless questions; she demands that they should devote the whole of their energy to preserve the faith intact and unsullied by any breath of error, and follow most closely him whom Christ has appointed to be the guardian and interpreter of the truth. There are to be found today, and in no small numbers, men, of whom the Apostle says that: “having itching ears, they will not endure sound doctrine: but according to their own desires they will heap up to themselves teachers, and will indeed turn away their hearing from the truth, but will be turned unto fables” (II Tim. iv. 34). Infatuated and carried away by a lofty idea of the human intellect, by which God’s good gift has certainly made incredible progress in the study of nature, confident in their own judgment, and contemptuous of the authority of the Church, they have reached such a degree of rashness as not to hesitate to measure by the standard of their own mind even the hidden things of God and all that God has revealed to men. Hence arose the monstrous errors of “Modernism,” which Our Predecessor rightly declared to be “the synthesis of all heresies,” and solemnly condemned. We hereby renew that condemnation in all its fulness, Venerable Brethren, and as the plague is not yet entirely stamped out, but lurks here and there in hidden places, We exhort all to be carefully on their guard against any contagion of the evil, to which we may apply the words Job used in other circumstances: “It is a fire that devoureth even to destruction, and rooteth up all things that spring” (Job xxxi. 12). Nor do We merely desire that Catholics should shrink from the errors of Modernism, but also from the tendencies or what is called the spirit of Modernism. Those who are infected by that spirit develop a keen dislike for all that savours of antiquity and become eager searchers after novelties in everything: in the way in which they carry out religious functions, in the ruling of Catholic institutions, and even in private exercises of piety. Therefore it is Our will that the law of our forefathers should still be held sacred: “Let there be no innovation; keep to what has been handed down.” In matters of faith that must be inviolably adhered to as the law; it may however also serve as a guide even in matters subject to change, but even in such cases the rule would hold: “Old things, but in a new way.” …
28. … The spirit of insubordination and independence, so characteristic of our times, has, as We deplored above, not entirely spared the ministers of the Sanctuary. It is not rare for pastors of the Church to find sorrow and contradiction where they had a right to look for comfort and help. Let those who have so unfortunately failed in their duty, recall to their minds again and again, that the authority of those whom “the Holy Spirit hath placed as Bishops to rule the Church of God” (Acts xx. 28) is a divine authority. Let them remember that if, as we have seen, those who resist any legitimate authority, resist God, much more impiously do they act who refuse to obey the Bishop, whom God has consecrated with a special character by the exercise of His power.
