1. The Church of God can be but one; because God is truth: and, truth can be but one. The world may, and (as a matter of fact) does abound in false Churches, just as it abounds in false deities; but, this is rendered possible only because they are false. Two or more true Churches involve a contradiction in terms. Such a condition of things is as intrinsically absurd, and as unthinkable, as two or more true Gods—as well talk of two or more multiplication tables! No! There can be but "One Lord, one Faith, one Baptism". If several Churches all teach the true doctrine of Christ, unmixed with error, they must all agree, and, consequently, be virtually one and the self same. There is no help for it; and sound reason will not tolerate any other conclusion. The "Branch Theory" stands self-condemned, if truth be of any importance: because it is inconsistent with truth. For, if one Church contradicts the other on any single point of doctrine, then one or the other must be false, that is, it must be either asserting what Christ denied; or else denying what Christ asserted. They cannot, under any circumstances, be described as true Churches. This is not sophistry or subtilty. It is common-sense. Christ promised unity in promising truth; since truth is one. Is Christ divided? asks St. Paul. No! Then neither is His Church.

2. How was His truth to be maintained and securely developed, century after century, pure and untainted, and free from all admixture of error? Humanly speaking, the thing was impossible. Then what superhuman guarantee did He offer? What was to be our security? Nothing less than the abiding presence of the Holy Ghost Himself.

Surely, then, we need not be anxious after that! Listen, and remember it is to God you are listening. "The Spirit of Truth shall abide with you for ever" (John xiv. 17). Non-Catholics do not seem in the least to realise what those words mean, or that it is God Himself who promises. But, to continue; what is the purpose of this extraordinary and enduring presence? Why is it given? What is it for? Well, for the express purpose of hindering divisions and sects. In order to lead, not to mislead us. How do we know? Because God said so: "He shall guide you into all truth" (John xvi. 13). And this truth, thus permanently secured, was to draw all together into one body. In fact, we have it on Divine authority, that the Church of Christ was to be as truly a single organic whole, in which every part is subject to one head, as is a living human body. The similitude is not of man's choosing, but is inspired by the Holy Spirit Himself. "As the (natural) body is one, and hath many members, and all the members of that one body, being many, are one body, so also is Christ.... Now, ye are the (mystical) Body[[7]] of Christ" (1 Cor. xii.).

What can be clearer, what more explicit? Now, if the Spirit of Truth, that is to say, the Holy Ghost, is really with the Church (as God promised He always would be), and if He is always present for the express purpose of "guiding her into all truth" (as God promised would be the case), surely this guidance must be a great reality, and not the mere sham that it is everywhere found to be, outside the Catholic Church.

3. Consciously or unconsciously, Anglicans and other non-Catholics have for centuries denied the truth of Our Lord's words and have contradicted His clearest statements. In fact, the Church of England, in her Book of Homilies, declares that "clergy and laity, learned and unlearned, all ages, sects, and degrees of men, women, and children, of whole Christendom, were altogether drowned in damnable idolatry by the space of 800 years and more"! (Hom. on Peril of Idol., part iii.). This is a specimen of the way in which God's promises are set aside, and the Bible misinterpreted by outsiders while professing to make it the foundation of their creed. Nor was this the teaching of a few irresponsible persons. It was enforced by the whole Anglican Church. "All parsons, vicars, curates, and all others having spiritual cure," were "straitly enjoined" to read these Homilies Sunday after Sunday throughout the year in every church and chapel of the kingdom. And the 25th Article declares the second book of Homilies to contain "a godly and wholesome doctrine and necessary for these times"! Probably this "godly and wholesome doctrine" is no longer obliged to be read and taught by Anglicans; probably they no longer consider it either "godly" or "wholesome," but quite the reverse. This we are quite ready to admit. But, in the name of common prudence, who, in his senses, would trust the salvation of his immortal soul to a Church that teaches a thing is white in one century and black in the next, and never knows its own mind?

Here then let us put two very pertinent questions, for our non-Catholic friends to ponder over, and to answer, if they can. First: How is it possible for the Church to go astray, if God the Holy Ghost is really guiding? Second: How is it possible for the Church to wander away into error, if this same Spirit be leading her into all truth? Will some one kindly explain that, without at the same time denying the veracity of God?

4. However, granting the absolute truth of Christ's promises, we may now proceed to inquire in what way this divine and (because divine) infallible guidance into all truth is brought about? Is it by the Holy Spirit whispering to each individual priest or to each individual Bishop? Emphatically not. Why not? Because, if that theory were well founded, then every priest and Bishop would believe and teach precisely the same set of doctrines, without any need of an infallible Pope to guide him. For, clearly, the Spirit of Truth could not whisper "yea" to one, and "nay" to another, nor could He declare a thing to be "black" to one person and "white" to his neighbour. In fine, we have but two alternatives to choose from. We must confess either that the promises themselves, so solemnly made, are lies (which were blasphemy to affirm), or else, that God directs His Church, and safeguards its truth, through its head, or chief Pastor; just as we regulate and control the members of the physical body through the brain. We must either renounce all belief in Christ and His promises, or else admit that His words are actually carried out, and that the prayer has been heard which He made for Peter, and for those who should, in turn, exercise Peter's office and functions, and should speak in his name. Harken to the narrative, as given by St. Luke: "The Lord said: Simon, Simon, behold, Satan hath desired to have you [observe, the plural number] that he may sift you as wheat; but I have prayed [not for all, but] for thee, that thy faith fail not: and thou, being once converted, confirm thy brethren" (Luke xxii. 32) [observe the singular number, "thee," "thy" and "thou">[.

Peter still lives, in the person of Pope Pius X., and in virtue of that prayer, and through the omnipotent power of God, Peter still "confirms his brethren," and will continue to confirm them in the true and pure doctrine of Christ, until the final crack of doom. As the venerable Bishop W.B. Ullathorne wrote to Lady Chatterton, soon after the Vatican Council, i.e., 19th November, 1875: "There is but one Church of Christ, with one truth, taught by one authority, received by all, believed by all within its pale; or there is no security for faith. If we examine Our Lord's words and acts, such a Church there is. If we follow the inclinations of our fallen nature, ever averse to the control of authority, we there find the reason why so many who love this world, receive not the authority that He planted, to endure like His primal creation, to the end."

"It is pleasant to human pride and independence to be a little god, having but oneself for an authority, and a light, and a law to oneself. But does this or does it not contradict the fact that we are dependent beings, and that the Lord, He is God? This spirit of independence, with self-sufficiency for its basis, and rebellion for its act, is just what Sacred Scripture ascribes to Satan" (p. 230).

True. And it is just the reverse of the disposition that Christ demands from all who wish to enter into His One Fold: for He declares with startling clearness that "unless we become as little children" (i.e., docile, submissive, trustful, etc.) "we shall not enter into the Kingdom of heaven," which is His Church.
