2Who is the Holy Spirit? What is his role in our salvation? How do we cooperate with him to experience the fullness of his presence? How do we receive his fruits and exercise his gifts? These are a few of the questions explored in this nine-week Bible study, which is designed to help Catholics grow in their appreciation of the Holy Spirit and his power to transform their lives in Christ. The many relevant Scripture passages, combined with wisdom from the saints, the Catechism, and church tradition, make this a truly inspired Bible study.
