This monologue podcast episode of "The Catechism in a Year" focuses on explaining the nature of faith. Fr. Mike Schmitz begins by defining faith as both a gift from God (grace) and a free human act of assent to God's revealed truth. He emphasizes that true faith involves a complete submission of intellect and will to God, not a selective acceptance of beliefs. The episode uses examples from scripture and St. Thomas Aquinas to illustrate this point, concluding with an encouragement to pray for the gift of faith and to strive for a complete, unwavering belief in God's word. A key takeaway is that exercising faith is not contrary to human freedom or reason, but rather a fulfillment of them.
