The Doctrine of Infallibility for me correlates with inerrancy. Infallibility is the audacity of saying my/our religion can’t err because I/we have the truths and the Truth. Infallibility is about being right categorically, absolutely, and without exception. Infallibility proclaims the inerrancy of the Bible. In 1870, the Roman Catholic Church formally promulgated the doctrine of papal infallibility on matters of faith and doctrine. However, all religions have some doctrinal forms of infallibility and an irrevocableness of their doctrine. All institutionalized religions at some level believe they are infallible, are invincible, and have their own fabrication of truths and Truth that says they can’t err.
