The problem of new religious movements

The period following the Second World War has seen an unprecedented burst of religious creativity on a world scale. In North America and Western Europe, revivalist, evangelical and reformist movements have not only reshaped the face of Protestantism but have also rocked the stability of the Roman Catholic church. Cults and new religions have sprouted in profusion, old religions such as witchcraft and the occult movements have acquired new life, and missionaries from Asia have successfully introduced varieties of Hinduism, Buddhism and Islam into the West.
