I read St. Anthony Mary Claret’s autobiography a while back and he lamented that even in his time (mid 1800s) the faithful were becoming increasingly ignorant, misinformed and led astray, primarily by the media–in his day newspapers, books, and pamphlets. As he said then, “The right to speak out and teach the nations, which the Church received from God Himself in the person of the Apostles, has been usurped by a mob of obscure journalists and ignorant charlatans.”
How much more is that the case today with radio, tons of TV channels, the internet, movies, etc., etc., etc.? These things become the teachers rather than the Church.
It’s a difficult battle. The best we can do is try and share the faith with who we can and pray the Jesus light the way amidst the darkness.
