Christianity and Freemasonry
The denomination with the longest history of objection to Freemasonry is the Roman Catholic Church. The objections raised by the Roman Catholic Church are based on the allegation that Masonry teaches a naturalistic deistic religion which is in conflict with Church doctrine.[69] A number of Papal pronouncements have been issued against Freemasonry. The first was Pope Clement XII's In Eminenti, 28 April 1738; the most recent was Pope Leo XIII's Ab Apostolici, 15 October 1890. The 1917 Code of Canon Law explicitly declared that joining Freemasonry entailed automatic excommunication.[70] The 1917 Code of Canon Law also forbade books friendly to Freemasonry.
In 1983, the Church issued a new Code of Canon Law. Unlike its predecessor, it did not explicitly name Masonic orders among the secret societies it condemns. It states in part: "A person who joins an association which plots against the Church is to be punished with a just penalty; one who promotes or takes office in such an association is to be punished with an interdict." This omission caused both Catholics and Freemasons to believe that the ban on Catholics becoming Freemasons may have been lifted, especially after the perceived liberalisation of Vatican II.[71] However, the matter was clarified when Cardinal Joseph Ratzinger (later Pope Benedict XVI), as the Prefect of the Congregation for the Doctrine of the Faith, issued Quaesitum est, which states: "... the Church’s negative judgment in regard to Masonic association remains unchanged since their principles have always been considered irreconcilable with the doctrine of the Church and therefore membership in them remains forbidden. The faithful who enroll in Masonic associations are in a state of grave sin and may not receive Holy Communion." Thus, from a Catholic perspective, there is still a ban on Catholics joining Masonic Lodges. For its part, Freemasonry has never objected to Catholics joining their fraternity. Those Grand Lodges in amity with UGLE deny the Church's claims and state that they explicitly adhere to the principle that "Freemasonry is not a religion, nor a substitute for religion."[28]
In contrast to Catholic allegations of rationalism and naturalism, Protestant objections are more likely to be based on allegations of mysticism, occultism, and even Satanism.[72] Masonic scholar Albert Pike is often quoted (in some cases misquoted) by Protestant anti-Masons as an authority for the position of Masonry on these issues. However, Pike, although undoubtedly learned, was not a spokesman for Freemasonry and was controversial among Freemasons in general, representing his personal opinion only, and furthermore an opinion grounded in the attitudes and understandings of late 19th century Southern Freemasonry of the USA alone. Indeed his book carries in the preface a form of disclaimer from his own Grand Lodge. No one voice has ever spoken for the whole of Freemasonry.[73]
