The fraternity’s policy regarding religion is another critical source of external criticism and misunderstanding. To be accepted, a candidate must profess a belief in a Supreme Being, often referred to universally within the Lodge as the Great Architect of the Universe (GAOTU), yet Freemasonry itself is explicitly not a religion, and proselytizing or discussing specific religious doctrines is strictly forbidden within the Lodge. This non-denominational spiritual requirement means Masons can be drawn from Christianity, Islam, Judaism, Buddhism, and other faiths, aiming to unite men of good character regardless of their sect. This philosophical stance, however, has historically led to staunch opposition and condemnation from various organized religions, most notably the Catholic Church, which views the fraternity's rites and non-denominational theology as incompatible with its dogma.
