The Vatican Publishing House LEV releases Pope Francis “Saints, not worldly. God’s grace saves us from interior corruption” , a new book collecting two texts published at different times: an article dating back to 1991, with the original title “Corrupción y pecado” , then republished in 2005, when Jorge Maria Bergoglio was Archbishop of Buenos Aires, and the Letter he addressed to the priests of the Diocese of Rome in August 2023. We publish the English translation of his preface.
