Contemporary Paganism has been defined as "a collection of modern religious, spiritual, and magical traditions that are self-consciously inspired by the pre-Judaic, pre-Christian, and pre-Islamic belief systems of Europe, North Africa, and the Near East." Thus it has been said that although it is "a highly diverse phenomenon", "an identifiable common element" nevertheless runs through the Pagan movement. Strmiska described Paganism as a movement "dedicated to reviving the polytheistic, nature-worshipping pagan religions of pre-Christian Europe and adapting them for the use of people in modern societies." The religious studies scholar Wouter Hanegraaff characterised Paganism as encompassing "all those modern movements which are, first, based on the conviction that what Christianity has traditionally denounced as idolatry and superstition actually represents/represented a profound and meaningful religious worldview and, secondly, that a religious practice based on this worldview can and should be revitalized in our modern world."
