    • n infallibility The quality of being infallible, or incapable of error or mistake; entire exemption from liability to error. In theology the doctrine of the infallibility of the church is the doctrine that the church as a whole cannot err in its spiritual faith and its religious teaching, and that consequently the religious teaching of the church is infallibly true. In Roman Catholic theology the doctrine of the infallibility of the Pope is the doctrine that when the Pope speaks ex cathedra (that is, when he speaks officially and on matters of faith and morals) he is divinely guarded from all error. The theory of the Pope's official infallibility was long maintained by ultramontane theologians as the basis of pontifical supremacy; but it was first promulgated as a binding dogma by the Vatican Council in 1870, in the restricted form above given. See Old Catholics, under catholic.
    • n infallibility Incapability of failure; absolute certainty of success or effect: as, the infallibility of a remedy.
