The Inquisition is one of the darkest chapters in the history of the Catholic Church and remains one of the most controversial and misunderstood subjects. Established in the thirteenth century, the Inquisition aimed to preserve orthodoxy and combat heresy, but in many cases it led to abuses of power, unfair trials and torture. The Church has struggled for centuries to explain and contextualize this period of its history, but the word “inquisition” remains synonymous with intolerance and persecution.

Historical Context: The Inquisition arose at a time when heresy was seen not only as a theological error but also as a threat to social order and political unity. The Church believed that protecting the purity of the faith was essential for the salvation of souls, and that this justified methods we consider unacceptable today. Although the Inquisition was not exclusively Catholic (there were Protestant inquisitions in some countries), the use of torture and execution deeply tarnished the Church’s image.

The Case of Galileo Galilei: Galileo’s trial is an iconic example of tensions between the Church and science. Galileo was condemned for supporting Copernicus’s heliocentric theory, which stated that the Earth revolved around the Sun. Although the Church now recognizes the validity of these theories, Galileo’s condemnation has become a symbol of the Church’s supposed opposition to scientific progress. In 1992, Pope John Paul II officially declared that the Church had made an error in this case, marking an attempt at reconciliation with scientific thought.
