Growth of religionGrowth of religion involves the spread of individual religions and the increase in the numbers of religious adherents around the world. In sociology, desecularization is the proliferation or growth of religion, most commonly after a period of previous secularization. Statistics commonly measure the absolute number of adherents, the percentage of the absolute growth per-year, and the growth of converts in the world. Studies in the 21st century suggest that, in terms of percentage and worldwide spread, Islam is the fastest-growing major religion in the world.
Witch-cult hypothesisThe witch-cult hypothesis is a discredited theory that the witch trials of the Early Modern period were an attempt to suppress a pagan religion that had survived the Christianization of Europe. According to its proponents, accused witches were actually followers of this alleged religion. They argue that the supposed 'witch cult' revolved around worshiping a Horned God of fertility and the underworld, whose Christian persecutors identified with the Devil, and whose followers held nocturnal rites at the witches' Sabbath.
UrmonotheismusThe term Urmonotheismus (German for "primeval monotheism") or "primitive monotheism" expresses the hypothesis of a monotheistic Urreligion, from which polytheistic religions allegedly degenerated. This evolutionary view of religious development contrasts diametrically with another evolutionary view on the development of religious thought: the hypothesis that religion progressed from simple forms to complex: first pre-animism, then animism, totemism, polytheism, and finally monotheism.
