We know the objection with which we shall be met. Peter may speak, it will be urged, and not wish to exert the plenitude of his doctrinal power. Yes; but when he restrains thus within voluntary limits the exercise of his authority, he gives us to understand it clearly. He is careful, in order not to overtax our weakness, to apprise us that, notwithstanding the obligation with which he binds consciences, it is not in his mind, as yet, to deliver a definitive sentence upon the doctrine. Frankly, does the Syllabus offer to us an indication, however faint, of any such reserve? What more definitive than a judgment formulated in these terms: “This is error, that is truth”? Is any revision possible of such a judgment? Is it possible to be revoked or abrogated? Does it not settle us necessarily in an absolute conclusion which excludes all possibility of diminution or of change? In a word, can the assertion be ever permissible--“Error in these days, truth in others”? It may be added that, by the admission of all, friends and enemies--an admission confirmed by the declaration of the cardinal secretary of state, the Syllabus is an appendix to, and as it were a continuation of, the bull _Quanta cura_, to which no one can reasonably refuse the character of a definitive and irreformable decree; and it will be understood how unreasonable it would be to despise the evidence of facts, in order to cling to an objection without consistency, and which falls of itself for want of a solid foundation.
