In this lesson, Bishop Barron explores Catholic spirituality, which is centered on prayer. As the Catechism of the Catholic Church states: “Prayer is the lifting up of the mind and the heart to God.” On pilgrimage to the places where the great saints and spiritual masters lived, Bishop Barron explores the different types of prayer: contemplation; adoration; petition; and intercession. In telling the stories of Catholics like Thomas Merton, St. Theresa of Avila and St. John of the Cross, Bishop Barron demonstrates how the human person can be transformed through prayer that manifests a deep, spiritual commitment centered in Christ.
