The supreme head of Christ's army--of Christ's Church upon earth, is our Sovereign Lord the Pope. Some will not accept his rule, and refuse to admit his authority. But this is not only to be expected. It was actually foretold. As they cried out, of old, to one even greater than the Pope, "We will not have this man to reign over us" (Luke xix. 14), so now men of similar spirit repeat the self-same cry, with regard to Christ's vicar. Nevertheless, wheresoever his authority is loyally accepted, and where submission, respect and obedience are shown to him, there results the order and harmony and unity promised by Christ: while, on the contrary, where he is not suffered to reign there is disorder, rivalry and sects. To be able to look forward and to foresee such opposite results would perhaps need a prophetic eye, an accurate estimate of human nature, and a very nice balancing of cause and effect. It could be the prognostication only of a wise, judicious, and observant mind. But we are now looking, not forwards, but backwards, and in looking backwards the case is reduced to the greatest simplicity, so that even a child can understand; and "he that runs may read". The simplest intelligence, if only it will set aside prejudice and pride, and just attend and watch, will be led, without difficulty, to the following conclusions: firstly, without an altogether special divine support, no authority can claim and exercise _infallibility_ in its teaching; and secondly, without such infallibility in its teaching no continuous unity can be maintained among vast multitudes of people, least of all concerning dogmas most abstruse, mysteries most sublime and incomprehensible, and laws and regulations both galling and humiliating to human arrogance and pride. It is precisely because the Catholic Church alone possesses such a supreme and infallible authority that she alone is able to present to the world that which follows directly from it, namely a complete unity and cohesion within her own borders. Yes! Strange to say: the Catholic Church to-day stands alone! There is no rival to dispute with her, her unique and peerless position. Of all the so-called Christian Churches, throughout the world, so various and so numerous, and, in many cases, so modern and so fantastic, there is not a single one that can approach her, even distantly, whether it be in (_a_) the breadth of her influence, or in (_b_) the diversity and dissimilarity of her adherents, or in (_c_) the number of her children, or in (_d_) the extent of her conquests, or (_e_) in the absolute unity of her composition.
