So much interesting stuff in this convo, particularly @mfjlewis's "personal testimony" and @SamRochadotcom's rejection of the post-Vatican II "narrative of decline." https://soundcloud.com/where-peter-is/sam-rocha-stories-and-remembrance
There was no failure of catechesis after the Council. Catholics have never been especially well catechised. Joan of Arc's understanding of catechesis was learning the Our Father & Hail Mary. In an age of unprecedented literacy, Catholics have an unprecedented level of knowledge.
The 40's & 50's weren't a golden age of Catholicism. This is literally just the racist, sexist "baby boomer" narrative of decline, applied to Catholicism. It's no wonder the traditionalist movement is 99% MAGA now. It's ideology, not history, and certainly not theology.
