Fides et Ratio (Latin: faith and reason) is an encyclical promulgated by Pope John Paul II on 1988-09-15. It deals primarily with the relationship between faith and reason. The Pope in this encyclical condemns modern philosophies bound with nihilism and relativism. He advocating a faith tempered by reason. He writes "This is why I make this strong and insistent appeal — not, I trust, untimely — that faith and philosophy recover the profound unity which allows them to stand in harmony with their nature without compromising their mutual autonomy. The parrhesia of faith must be matched by the boldness of reason." Philosophy, according to this encyclical, is means of understanding divine revelation in a more complete way.

“Fideism” is the name given to that school of thought—to which Tertullian himself is frequently said to have subscribed—which answers that faith is in some sense independent of—if not outright adversarial toward—reason.
“Fideism” is thus to be understood not as a synonym for “religious belief,” but as denoting a particular philosophical account of faith's appropriate jurisdiction vis-a-vis that of reason.
One lesson to be gleaned from the preceding cases is that “fideism” is a term that is seldom self-applied.
