 In the spiritual literature of Christianity, the concept of pilgrim and pilgrimage may refer to the experience of life in the world (considered as a period of exile) or to the inner path of the spiritual aspirant from a state of wretchedness to a state of beatitude.Pilgrims and the making of pilgrimages are common in many religions, including the faiths of ancient Egypt, Persia in the Mithraic period, India, China, and Japan.The Greek and Roman customs of consulting the gods at local oracles, such as those at Dodona or Delphi, both in Greece, are widely known.
