This booklet outlines the nature and value of indulgences in consideration of the new regulations placed upon them. These new regulations are designed to inspire the practice of making reparaition for ourselves and for the poor souls of Purgatory. Taken from the official Enchiridion of Indulgences. Many Catholics do not even know what a plenary indulgence is, let alone how to gain one. Extremely useful for understanding the spiritual power and importance of indulgences.Â
