Drawing on Scripture and the wisdom of the Fathers, Doctors, and mystics, this illuminating work restores devotion to the often neglected Third Person of the Holy Trinity. It explores the Holy Spirit’s presence in the Old and New Testaments, His role in the life of Christ and the mission of the Church, and the gifts and charisms He bestows for our sanctification. With practical guidance for growing in docility and awareness of His indwelling, these pages reveal the consequences of forgetting the Spirit and the joy that flows from honoring Him. Rooted in solid theology, this book invites readers to live more fully as temples of the Spirit and to be transformed by His sanctifying love.
