I just ran across this great website. It has good articles on how to think like a Catholic. It is important to study the faith. The world is constantly teaching us how to think in a secular way, to live as if there is no God and no heaven or hell. When we embrace the faith and feed our intelligence with the truths of the faith it keeps our eyes on what truly matters. Truth is the food of our souls. If we do not feed the soul it will die.
