When I was in Catholic high school, to provide but one example, I took a mandatory religion class in which Jonathan Livingston Seagull by Richard Bach was one of the required texts. This was fairly typical of the catechetical infidelity that dominated the era in many parishes and schools in the United States.
Instead of introducing us to great Catholic literature, we were given this sort of tripe (from Bach’s book): “We can lift ourselves out of ignorance, we can find ourselves as creatures of excellence and intelligence and skill. We can be free! We can learn to fly!”
