Book excerpt: The Soul of the Apostolate was the favorite book of Pope St. Pius X. This book shows how prayer is the soul of every apostolic work and is absolutely critical for apostolic success. Explores all the proved methods of developing and maintaining the interior life amid the bustle of daily activity. This excellent book will help you to understand the economy of salvation, as well as the many dead-ends that we fallen creatures tend to follow. A critically important introduction to the spiritual life! This important book has been recommended by Pope St. Pius X and his successor, Pope Benedict XV. Pope St. Pius X said, "If you desire that God should bless your apostolate and make it fruitful, undertake everything for His glory, saturate yourself and your devoted fellow-workers with the spirit of Jesus Christ, animating yourself and them with an intense interior life. To this end, I can offer you no better guide than The Soul of the Apostolate by Dom Chautard, Cistercian Abbot. I warmly recommend this book to you, as I value it very highly, and have myself made it my bedside book."
