The Soul of the Apostolate by Matthew Arnold
The Soul of the Apostolate was the favorite book of Pope St. Pius X. Matthew Arnold presents excerpts from a timeless classic that show how prayer is the soul of every work for God and is absolutely critical for apostolic success. This foundational work on the spiritual life will help you understand that the Lord first desires prayer, and then our works, and will help you to avoid serious spiritual mistakes.
