It is a fact of divine revelation that the soul of every person who dies in the state of grace, but without having made sufficient expiation on earth for his forgiven sins, will undergo the punishment and purification of Purgatory before entering Heaven. In this fascinating book, Father Schouppe presents the ancient Catholic tradition on Purgatory, explaining how its pains are excruciating - greater than any suffering known on earth, how they are adapted to the past sins of each individual soul, how they can vary in duration from less than one minute to a period of several centuries, and how they manifest the infinite mercy of God no less than His justice. On many occasions God has allowed souls in Purgatory to appear on earth to plead for prayers, sacrifices, and Masses for their relief; in Purgatory Explained the reader will find scores of true stories of apparitions and revelations on Purgatory taken from the lives of St. Margaret Mary, St. Teresa of Avila, St. Bridget of Sweden, St. Gertrude the Great, St. Francis de Sales, St. Catherine of Genoa, St. Magdalen de Pazzi, St. Lidwina of Schiedam, St. Margaret of Cortona, St. Thomas Aquinas, and the Cure of Ars. These amazing revelations all emphasize the wonderful relief which the souls in Purgatory receive from prayers, penance, almsgiving, and especially from the Holy Sacrifice of the Mass offered for them. Moreover, these stories describe the measureless gratitude of the souls in Purgatory, and the priceless benefits which they obtain for their benefactors in return.
