Pseudoreligion or pseudotheology is a pejorative for a non-mainstream belief-system or philosophy which is functionally similar to a religious movement, typically having a founder, principal text, liturgy and faith-based beliefs.[1][2]
Belief systems such as Christian Science[3] or Nation of Islam[4] have been referred to as pseudoreligions, as have various New Age religions, as well as political ideologies such as Nazism and Positive Christianity.[5]
Examples of marginal movements with founding figures, liturgies and recently invented traditions that have been studied as legitimate social practices include various New Age movements,[6] and millennaristic movements such as the Ghost Dance and South Pacific cargo cults.[7]
In 1963, German-American philosopher Paul Tillich introduced a distinction between pseudo-religions and quasi-religions. He described pseudo-religions as movements which intentionally deceive adherents through their similarities with mainstream religions, while quasi-religions are non-religious movements which have unintended similarities to religions.[8]
William Buckley's more conservative National Review dubbed the group a "pseudo-religion." Writing in Ebony, Hans J. Massaquoi concurred, calling the Nation of Islam a "quasi-religion."
Sometimes, what I call quasi-religions are called pseudo-religions, but this is as imprecise as it is unfair. 'Pseudo' indicates an intended but deceptive similarity; 'quasi' indicates a genuine similarity, not intended, but based on points of identity, and this, certainly, is the situation in cases like Fascism and Communism, the most extreme examples of quasi-religions today.
