Rev. R. P. Quadrupani, Barnabite

Rev. R. P. Quadrupani, Barnabite, was a notable Italian Barnabite priest who lived from 1740 to 1807. He is best known for his work Light and Peace — Instructions for Devout Souls to Dispel Their Doubts and Allay Their Fears which was originally published in Italian in 1795. This book provides guidance for devout Christians in their daily spiritual lives and has been translated into multiple languages, including English, French, and others. It is considered a valuable resource for those seeking spiritual direction and comfort, particularly for those who struggle with scrupulosity or anxiety. The book emphasizes obedience to spiritual directors and the importance of common sense in spiritual matters, making it particularly relevant to the American character according to some translations.
