This spiritual classic that answers the key questions about reparation: Why reparation should be made? Who ought to make it? And How should it be made? The great Jesuit guide Raoul Plus wrote in an era of immense suffering - war, early death, and religious indifference that co-existed with true and healthy Catholicism. He called not for scientific advance but for spiritual maturity. Fr. Plus explained every facet of reparation for individual penitents, including: In what reparation consists, Why Our Lord wants it and makes it a fundamental obligation, Separate chapters about priestly, religious and lay reparation, How to grasp, and teach others, the terrible seriousness of human life, Dozen Scriptural passages that anchor reparation theology, Links to Holy Mass and why you cannot attend one without seeing to the other, three factors indispensable to developing the spirit of reparation, and compensating for the sins of others. Fr. Plus's book is rich with prayers, spiritual guidance briefly expressed, Biblical quotations on the topic and its centrality to perfecting one's spiritual life...and anecdotes illustrating his hundreds of points.
