A classic in Catholic spirituality, Light and Peace: Instructions for Devout Souls to Dispel Their Doubts and Allay Their Fears was first written in Italian by Fr. Carlo Giuseppe Quadrupani in 1795. It has since passed through innumerable editions in Italian, French, German, and English.

A summary of spiritual guidance for earnest Christians in the ordinary duties of life in the world, Light and Peace is a handbook for getting to Heaven. It provides a short and practical course in proper Christian living that covers all the important aspects of our religious duties, with an emphasis on peace and tranquility of heart. By far the most salient features of this little book are its immense common sense and down-to-earth advice. In addition, Fr. Quadrupani gives heartfelt and encouraging counsel to those suffering from anxiety and scrupulosity, an unfortunately common plague among those seeking to be devout.

Light and Peace shows that growing in perfection is not a complicated endeavor, but rather one that requires practical thinking and a knowledge of the task at hand—in short, light on the path, which is what this book provides. The result of knowing where we are going spiritually and how best to achieve our eternal end is peace—that peace Our Lord promised that the world can neither give nor take away.
