Dealings with the Inquisition or, Papal Rome, Her Priests, and Her Jesuits" is a memoir written by Giacinto Achilli, an Italian Ex-Dominican friar. First published in 1851, the book tells the story of Achilli's adventures in the Catholic Church, including his time spent in the Dominican order and his later run-ins with the Jesuits and the Inquisition. Giacinto Achilli provides an in-depth analysis of the Catholic Church's internal operations, highlighting the Jesuit order's influence and the Inquisition's methods. He talks about how the Inquisition's repressive methods and the Church's dogma have demoralized him. The story exposes the supposed wrongdoing, deceit, and secrecy in the Church hierarchy and offers a critical viewpoint on Papal Rome's operations. The memoir also touches on more general topics like censorship, religious intolerance, and the silence of dissident voices inside the Catholic Church. A more comprehensive knowledge of the power relationships and disputes inside the Church in the 19th century is made possible by Achilli's experiences as a defector and his disclosures regarding the Inquisition.
