But what need is there for searching for proofs? A single reflection banishes every difficulty. We have in the church two means for ascertaining whether a pontifical act is, or is not, a sovereign definition, an infallible decision. We have to enquire of the pontiff who is the author of it, or the people who subordinate themselves to his teaching. Neither one nor the other can deceive us in the answer they give. The divine promise continues equally assured in both: in the former, when he teaches; in the latter, when they listen and obey. It is what the theologians call active and passive infallibility. Admit that Pius IX. had left us in ignorance; that he published the Syllabus, but did not tell us what amount of assent he required of us. Well, none of us are in any doubt as to that. How many times has not this people said, how many times has it not repeated with an enthusiasm inspired by love, that this Syllabus, despised, insulted by the enemies of the church, they accept as the rule of their beliefs, as the very word of Peter, as the word of life come down from heaven to save us. Is it not thus that have spoken, one after the other, bishops, theologians, the learned and the ignorant, the mighty and the humble? Who amongst us has not heard this language? A celebrated doctor, Tanner, has said that in order to distinguish amongst the teachings of the church those which belong to its infallible authority, we must listen to the judgment of wise men, and above all consult the universal sentiment of Christians. If we adhere to this decision, it reveals to us our duties in regard to the sovereign act by which Pius IX. has withdrawn the world from the shadow in which it was losing its way, and has prepared for it a future of better destinies.
We have the more reason for acting thus as hell, by its furious hatred, gives us, for its part, a similar warning, and proclaims, after its fashion, the imperishable grandeur of the Syllabus. Neither has it, nor have those who serve it, ever been under any illusion in this respect. They have often revealed their mind both by act and word. What implacable indignation! what torrents of insults! what clamor without truce or mercy! And when importunate conciliators interfered to tell them they were mistaken, that the Syllabus was nothing or next to nothing, and need not provoke so much anger, how well they knew how to reply to them and to bury them under the weight of their contempt! At the end of 1864, at the moment when the struggle occasioned by the promulgation of the Encyclical and Syllabus was the most furious, an agency of Parisian publicity, the agency Bullier, could insert the following notice: “The Encyclical is not a dogmatic bull, but only a doctrinal letter. It is observable that the Syllabus does not bear the signature of the Pope. This Syllabus has besides been published in a manner to allow us to believe that the Holy Father did not intend to assign to it a great importance. One may conclude, therefore, that the propositions which do not attack either the dogma or morals of Catholics, and do not at all impeach faith, are not condemned, but merely blamed.” To these words, poor in sense, but crafty and treacherous in expression, the journal _Le Siècle_ replied as follows:
