The Grand Master of Florida Freemasonry has declared that Pagans (and agnostics and gnostics) can't be Masons and must resign.
The question has arisen if certain religious practices are compatible with Freemasonry, primarily Paganism, Wiccan and Odinism, and secondarily Agnosticism and Gnosticism.
[reasoning trimmed for space, see the link]
Therefore, as Grand Master, it is my Ruling and Decision that none of the above mentioned beliefs and/or practices are compatible with Freemasonry since they do not believe or practice one or more of the prerequisites to be a candidate for Masonry listed above. Further, any member of the Craft that professes to be a member of one of the groups mentioned above shall tender his resignation or suffer himself to a Trial Commission whose final outcome will be expulsion since there is no provision to allow anything contrary to the Ancient Landmarks. Furthermore, Freemasonry prohibits the change of any of the Ancient Landmarks, and its members admit that it is not in power of any man, or body of men, to make innovations in the body of Masonry.
Your Humble Servant and Brother,
Jorge L. Aladro, Grand Master
