"Two powers govern the world," wrote Pope Gelasius, to the Greek Emperor Anastasius, more than fourteen hundred years ago, "the spiritual authority of the Roman Pontiff, and the temporal power of kings". These two powers have for their end, one the spiritual happiness of man, here and hereafter, the other the temporal prosperity of society in the present world. So that, we may say, speaking generally, the Roman Pontiff has, in spiritual and ecclesiastical matters, the same authority that secular sovereigns and their Parliaments have in worldly and political matters. They command and issue laws not only as regards what is necessary for the welfare of their subjects, but also as regards whatever is lawful and expedient. It is not contended that they never make a mistake. It is not asserted that their ruling is necessarily, and in every particular, always wise and discreet, but even inexpedient orders, if not unjust, may be valid and binding, even though they might have been better non-issued. The principle to guide us is of practical simplicity. As regards both the Church and the State—each in its own order—the rule is that obedience is to be yielded. And, in doubtful cases the presumption is in favour of authority. If anything were ordered, which is clearly seen to be contrary to, or incompatible with the Law of God, whether natural or revealed, then, of course, it would possess no binding force, for the Apostle warns us that—"We must obey God, rather than man"—but, so long as we remain in a state of uncertainty, we are bound to give a properly constituted authority the benefit of the doubt—and submit.

4. With these preliminary explanations and considerations to guide us in our interpretation, we will now give the solemn teaching on the subject, as laid down in the third chapter of the Pastor Æternus, drawn up and duly promulgated by the Ecumenical Council of the Vatican; and therefore of supreme authority.

"We teach and declare that the Roman Church, according to the disposition of the Lord, obtains the princedom of ordinary power over all the other Churches; and that this, the Roman Pontiff's power of jurisdiction, which is truly episcopal, is immediate; towards which (power) all the pastors and faithful, of whatever right and dignity, whether each separately or all collectively, are bound by the duty of hierarchical subordination and true obedience, not only in the things which pertain to faith and morals, but also in those which pertain to the discipline and government (regimen) of the Church diffused through the whole world; so that, unity being preserved with the Roman Pontiff, as well of communion as of the profession of the same faith, the Church of Christ may be one flock under one pastor. This is the doctrine of Catholic truth, from which no one can deviate without loss of faith and salvation."

"We also teach and declare that the Roman Pontiff is the supreme judge of the faithful, and that in all causes belonging to ecclesiastical examination recourse can be had to his judgment: and that the judgment of the Apostolic See, than whose authority there is none greater, is not to be called in question, nor is it lawful for any one to judge its judgment. Therefore, those wander from the right path of truth who affirm that it is lawful to appeal from the judgments of the Roman Pontiffs to an Ecumenical Council, as to an authority superior to the Roman Pontiff."

"If any one, therefore, shall say that the Roman Pontiff has only the office of inspection or direction, but not full and supreme power of jurisdiction over the Universal Church, not only in the things which pertain to faith and morals, but also in those which pertain to the discipline and government of the Church diffused throughout the whole world, or that he has only the principal place (potiores partes), and not the whole plenitude of the supreme power, or that this, his power, is not ordinary and immediate, whether over all and each of the Churches, or over all and each of the pastors and faithful, let him be anathema!"

5. Since the Church is a perfect society, spread throughout the entire world, with one supreme ruler at its head, it follows that it must be endowed with all the means requisite for the carrying out of its mission. Christ was sent, by His Eternal Father, from Heaven with full powers. "All power is given me in heaven and in earth"; and these powers He handed on to His Church. "As the Father hath sent Me, so I also send you" (John xx. 21). Hence the Popes are, to use Scriptural phraseology, "ambassadors for Christ; God, as it were, exhorting by them" (2 Cor. v. 20); and no Catholic dare contest their power or jurisdiction.

Indeed, it would have been hopelessly impossible to carry on the government of the Church and to maintain unity amongst its ever-increasing numbers, if there were no supreme authority ready to assert itself; to correct errors; to resist abuses; and to restrain those who might introduce dissensions and differences. Of this fact, the present deplorable chaotic state of the Anglican and other non-Catholic Churches offers us abundant and forcible illustrations. From the very first the One True Church has not only taught, but ruled; not only spoken, but acted. And when any of her subjects have proved obstreperous and disobedient, and stubborn in their resistance to her orders, she has invariably turned them out of her fold, so that they should not infect and contaminate the good and the loyal. It was in this sense that St. Paul, the inspired Apostle, in the very first century of the Christian era, instructed Titus to construe and administer the law committed to his charge. After warning Titus that there are "many vain talkers and deceivers," St. Paul commands him "to rebuke them sharply, that they may be sound in faith". He adds further: "These things speak, and exhort, and rebuke, with all authority". But this was not all. He was not only to decide who were the "vain talkers and deceivers". Nor was he simply "to exhort and rebuke them sharply, and with all authority," that they might become "sound in the faith," but if they persisted after the first and second admonition, he was also to reject them, and thrust them out of the Church, as heretics. "Reject a heretic, after the first and second admonition" (Tit. iii. 10). Now Titus was neither an Apostle nor a Pope, but a simple Bishop. If then such were the powers invested in him, how much more fully still must this authority be inherent in the Vicar of Christ himself, who is the supreme head upon earth of the entire Church of God.

It is this prompt amputation of the diseased members, before the hideous canker has time to spread, that has kept the Church of God pure to this day, while heretical bodies have fallen into greater and greater spiritual decay. It is because she fearlessly and resolutely insists upon all her children accepting the truth, the whole truth, and nothing but the truth, that she presents to the world, century after century, with miraculous clearness and perspicuity, the Divine hall-mark of unity.

6. Outside the true Church of God there is no recognised voice strong enough to enforce any uniformity of belief. Though the Pope's authority was acknowledged throughout England for over one thousand years, yet at the time of the so-called Reformation, that Voice of God, speaking through Peter, was admitted no longer. Hence, as Cardinal Manning most truly observes: "The old forms of religious thought are now passing away in England. The rejection of the Divine Voice has let in the flood of opinion; and opinion has generated scepticism; and scepticism has brought on contentions without end. What seemed so solid once, is disintegrated. It is dissolving by the internal action of the principle from which it sprung. The critical unbelief of dogma has now reached to the foundation of Christianity, and to the veracity of Scripture. Such is the world the Catholic Church Sees before it at this day. The Anglicanism of the Reformation is upon the rocks, like some tall ship stranded upon the shore, and going to pieces, by its own weight and the steady action of the sea. We have no need of playing the wreckers. It would be inhumanity to do so. God knows that the desires and prayers of Catholics are ever ascending that all that remains of Christianity in England may be preserved, unfolded and perfected into the whole circle of revealed truths, and the unmutilated revelation of the Faith.

"It is inevitable that if we speak plainly we must give pain and offence to those who will not admit the possibility that they are out of the Faith and the Church of Jesus Christ. But, if we do not speak plainly, woe unto us, for we shall betray our trust and our Master. There is a day coming, when they who have softened down the truth, or have been silent, will have to give account. I had rather be thought harsh than be conscious of hiding the light which has been mercifully shown to me" (Temp. Mission, etc., p. 215).
