text: Just to the Internet. Heterodoxy is about early Church credal issues, not every word that comes from the pen of the Pope. By the way, the Filioque is considered Heterodox, an addition to the Creed by Rome. So much for it not changing or being corrected. DF was about the Church having a monopoly on explaining the revelation of scripture (which modern study has found is not pure revelation at all but a mix of myth, natural law reason, didactics and social commentary (in the OT) and pastoral letter and recalled events (NT). Such analysis is important in understanding scripture and morality. That Pio Nono did not think so does not surprise me. You should know better and if you don't, please seek the truth. Most parishes include programs on scriptural history at some point as do local Catholic colleges. Or just find a book on it that does not promote Triumphalism. And don’t put it down or walk out when something is said that you don’t agree with, starting with Eden.
