First published at the outbreak of World War II, The Holy Spirit answers the need of many people for “a deeper and more accurate knowledge of the Holy Spirit,” in the author’s words. The Holy Spirit’s role in creation as the fountain of life and the first of God’s gifts is studied along with the Spirit’s mission, divine filiation, and the principles of growth.

A detailed summary of the book has been prepared by Rev. Robert P. Bucciarelli to enhance reading of the text.
