I am doing a research paper about some of Church history. Do any of you know any place where I can find some quotes of popes who erred in the past in their beliefs? I don't mean recent popes, but popes who lived hundreds of years ago or so. I need this because some in-laws cannot understand what papal infallibility really means. Thank you.
There is not a single example in the entire history of the Church of a Pope teaching grave error against the Faith in his ordinary magisterium.
I meant in his private opinion. Such as John XXII believing that there is no private judgment after death. Or the pope of St. Ambrose's day who believed that one could be baptized in the Name of Jesus only and not the Father, Son, and Holy Ghost.
There are some rare examples of Popes erring as private individuals.
Such examples though have nothing to do with our present crisis, as the men claiming to be popes have taught heresy and error in their ordinary magisterium, and have promulgated evil universal laws.
