Pseudoreligion, or pseudotheology, is a generally pejorative term applied to 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. Belief systems such as Theosophy, corporate Kabbalism, Christian Science, and the Nation of Islam have all been referred to as pseudoreligions, as have various New Age religions, as well as political ideologies such as Nazism. Within the academic debate, political ideologies that resemble religion are sometimes referred to as political religions.
While the more serious-minded participants in these groups may prefer to consider themselves part of a proper religion, or not part of a religion at all, the mainstream ascribes to them a fringe status. Such groups as the Raëlian Church and Heaven's Gate, seen as dangerous, exploitative, secretive, or closed, have been classified as pseudoreligious cults.
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, and millennaristic movements such as the Ghost Dance and South Pacific cargo cults.

Rabbi Adin Steinsaltz: There is no spirit in it, no message in it. This is part of a general term toward the esoteric that seems to be a' la mode for the time being, but it is not important on any real level. At best, it is shallow and unimportant. At worst, it may become slightly dangerous for Judaism and for the people who get involved in it. To get involved in any kind of pseudo-science or pseudo-religion is always slightly dangerous for the religion.

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.
