Carlo Giuseppe Quadrupani

Born in 1740 and died in 1807, Carlo Giuseppe Quadrupani was an Italian Catholic priest in the Barnabite order, also known as the Clerics Regular of St. Paul. He is remembered chiefly as a spiritual writer whose books were meant to steady troubled consciences and encourage a more peaceful, trusting religious life.

His best-known work is Light and Peace, a collection of guidance for devout readers wrestling with doubt, fear, and scrupulosity. Descriptions of the book consistently note its connection to the teaching and spiritual tone of St. Francis de Sales, whose gentle, practical approach clearly shaped Quadrupani's own voice.

Although not a widely known literary figure today, his writing has endured because of its simplicity and kindness. Readers have continued to return to his work for clear, compassionate counsel that speaks to everyday spiritual struggles.
