The relationship between the Catholic Church and Masonry has always been heavily used in the history. Not only because of the hidden agitation of the loges, more because of the Enlightenment, that brought a massive loss of power for the Church, Masonry was combatted and antagonized.Masonry developed out of ancient secret societies and adopted as well lots of symbols and rituals from pre-Christian time. A certain ancestor does not exist, but at the beginning of 18th century, the loges spread from Great Britain fast and started to organize and structure themselves. In the time of the Enlightenment, Masonry came upon brisk interests and understanding for the new body of thought that upheld tolerance and humanity as highest principles. The Church observed these tendencies and the fast expansion of Masonry with great worries: At the peak of prosecution of Masonry in the 19th century, countless bulls and writings were issued in which the Catholic Church not only the membership in one of the loges damned but also penalized Masonry. Many freemasons also were victims of the inquisition. Nevertheless, the anticlerical and undogmatic attitude of Masonry dispersed in Europa and were in vogue especially in the expiring 19th century. Even the modernization progress and the beginning of the 20th century did not change the clerical attitude: The Codex Iuris Canonici from 1917 penalized explicitly the membership in a loge of Masonry and sanctioned this with excommunication. Up to the Second Vatican Council in the sixties, the relationship between the Catholic Church and Masonry did not improve. Later, the efforts of the Austrian cardinal Franz König and some Austrian freemasons lead to a gradual thawing. In the new version of the Codex Iuris Canonici from 1983, the terms “freemason” and “Masonry” vanished and because of this as well the sanction of excommunication. Today, the relationship between Catholic Church and Masonry is more or less liberalized and in future, the points of contact will accumulate this is what a Styrian freemason believes in.
