This is but an illustration of what may be observed equally in the spiritual order, although there it is attended by more disastrous consequences. Thus we find hundreds of Churches proclaiming themselves to be foundations of God, which Time, the old Justice who tries all such offenders, soon proves, most unmistakably, to be nothing but the contrivances of man. They may bear a certain external resemblance to the true Church, planted by the Divine Husbandman, but like the man-made acorns, they deceive all our expectations, and are wholly unable to redeem their promises, or to live up to their pretensions.
For, while one and all declare with their lips that they possess the truth as revealed by Christ, their glaring divisions, irreconcilable differences, and internal dissensions emphatically prove that the truth is not in them: and that they have been built, not on the rock, but on the shifting sand, and are the erections, not of God, but of feeble, fickle men.
On the other hand, the Catholic Church, amid a thousand sects, resembles the genuine acorn among the thousand imitations. Not only does she alone possess the whole truth; but she alone can stand up and actually prove this claim to the entire world, by pointing defiantly at her marvellous and miraculous unity—a unity so conspicuous, and so striking, and so absolutely unique, that even the hostile and bigoted Protestant press can sometimes scarcely refrain from bearing an unwilling testimony to it.
