In the New Testament, Jesus reassures the Apostles before he ascends to heaven by saying, You will receive power when the Holy Spirit comes upon you, and you will be my witnesses . . . to the ends of the earth." What of this Spirit? In what way was that Spirit manifested in Jesus' ministry on earth? What does it offer us? And ask of us? These reflections by the preacher to the papal household coalesce biblical and doctrinal thought on the gifts conferred by anointing in the Spirit - kingly, prophetic, and priestly - onto Christ and through Christ to the Church. As one well accustomed to illuminating the Word to his audience, Father Cantalamessa bestows on readers an understanding of the Holy Spirit that is both practical and profound."
