Infallibility
Infallibility is the quality of being incapable either of being deceived, or of leading others astray. Romanists, while acknowledging that God alone is naturally infallible, maintain that he has been pleased to transmit this quality, to some undefined extent, to the Church and to the popes, so that they are infallible in their decisions on all points of doctrine.
1. INFALLIBILITY OF THE CHURCH. — The following is a condensed view of the infallibility of the Church of Rome, as collected from her own authors. Dens affirms. "That the Church, in matters of faith and manners, can by no means err, is an article of belief. Moreover, infallibility in the Church may be considered in a twofold point of view: the one active and authoritative, which is called infallibility in teaching and defining; the other passive or submissive (obedientialis), which is called infallibility in learning and believing. Infallibility, considered in the first sense, refers to the Church with respect to the head or chief pontiff, and the prelates of the Church; although this infallibility would not regard the laity or inferior pastors; for, as a man is said to see, although his vision does not apply to all his members, but to his eyes only, so the Church, in like manner, is said to be infallible, although this infallibility refers only to the prelates. But if the Church is not considered with regard to its head, but as it embraces all the faithful, or laics, under the obedience of the pope, it is not proper to say it is infallible in teaching and defining, because its gift in this respect is not to teach, but to learn and believe; wherefore the Church, in this view, is said to be 'passably infallible,' or infallible in learning, believing, practicing, etc. Therefore it is impossible that the whole Church, obedient to the pope, should believe any thing as revealed, or practice any thing as good which is not such; hence it can be said that the sense of the universal Church is always true, and its practice or usage always good" (Dens, Theol., tom. 2,
De Ecclesia, No.80, De Infallibilitate Ecclesia). The same author affirms also that "the Church is an infallible judge of controversies of faith; that this authority is vested in the bishops only, especially in the pope, and that lay persons, priests, doctors, or others, have no part in making infallible decisions in the Church." He says the government of the Church is a monarchy with regard to its head, but, at the same time, tempered with an aristocracy. A unanimous consent is not necessary to make a decision infallible; a majority is sufficient for this purpose. He also. says that a tacit consent is sufficient to make a decision infallible; for to be silent is to consent. Hence he concludes that "'when the pope defines anything, and the majority of bishops do not object, it is impossible that this definition should embrace error" (Dens, Theol. tom. 2, No. 82, Qualis esse debeat Consensus Episcoporum). "From the above we collect four principal systems which concern the seat of infallibility, and these contain a considerable number of subdivisions; the chief of which are expressed in the following analysis.
