The Christian countercult movement or Christian anti-cult movement is a social movement of certain Protestant evangelical and fundamentalist and other Christian ministries ("discernment ministries") and individual activists who oppose religious sects they consider "cults".
Christian countercult activism stems mainly from evangelicalism or fundamentalism. The countercult movement asserts that particular Christian sects whose beliefs they deem to be partially or wholly not in accordance with the Bible are erroneous. It also states that a religious sect can be considered a cult if its beliefs involve a denial of what they view as any of the essential Christian teachings such as salvation, the Trinity, Jesus himself as a person, the ministry and miracles of Jesus, his crucifixion, his resurrection, the Second Coming and the Rapture.
Countercult ministries often concern themselves with religious sects that consider themselves Christian but hold beliefs thought to contradict the Bible, including The Church of Jesus Christ of Latter-day Saints, the Unification Church, Christian Science, and Jehovah's Witnesses. Anti-Catholic movements have led Protestants to classify Catholicism as a cult. John Highham described anti-Catholicism as "the most luxuriant, tenacious tradition of paranoiac agitation in American history". Some also denounce non-Christian religions such as Islam, Wicca, Paganism, New Age groups, Buddhism, Hinduism and other religions.
