Faith is not the resignation of reason in view of the limits of our knowledge; it is not a retreat into the irrational in view of the dangers of merely instrumental reason. Faith is not the expression of weariness and flight but is courage to exist and an awakening to the greatness and breadth of what is real. Faith is an act of affirmation; it is based on the power of a new Yes, which becomes possible for man when he is touched by God.
--Cardinal Joseph Ratzinger (Pope Benedict XVI), A Turning Point for Europe?
