I am a Catholic who is heavily involved in adult faith education, and and I can very safely say everyone in the Church thinks this is a terrible idea except for the tech people that make these models. These things are all independent projects.

Because of the nuance involved in explaining theological concepts there's a long, long history of reviewing and approving books that explain doctrine. LLM outputs can be reviewed by a competent authority and approved for publication but releasing an AI to explain the theology to the general public in any sort of official way is impossible.
