In fact, the party that is now most deeply involved in the study of Freemasonry is their biggest enemy—the Church. As early as 1738, which was 19 years after the establishment of modern Freemasonry, Pope Clement XII condemned this organization.
His successor, Benedict XIV, even summarized the six threats posed by Freemasonry to Catholicism.
According to the information Leonard Ethan had previously obtained, the Church has been equating Freemasonry with the devil Satan throughout the 300 years since the establishment of modern Freemasonry. And this hatred has continued to this day.
Fortunately, the principle that the person who understands you most is your enemy applies universally, so from the information left by the Church, Leonard also gained some general knowledge about Freemasonry.
