If the church is Universal, then it only makes sense that culture would need to entwine with the spiritual Christian beliefs. In earlier times, in Catholic schools, mythology was a required subject. Nowadays, it's nearly ignored in all higher education. How do we know where we're going if we don't know where we've been?
There was a lot of good in paganism, not just superstition. Maybe still.
Thank you quiplet for your comment! I think that crucial thing is to critically reflect everything that culture offers to us: keep the good and what is valuable and reject what contradicts the dignity of a human person and person's growth.
