The Cult
No ancient cult of Hwanin is attested. As the celestial father in the Dangun foundation myth, he belongs to a mythological genealogy—Hwanin, Hwanung, Dangun—rather than to an excavated temple or priesthood. Later Korean religious history mapped the name onto the high god of heaven: the term Hananim was adopted by nineteenth-century Korean Christians as a vernacular name for the biblical God, while Ch'oe Che-u's Donghak movement spoke of Haneullim. The cult is therefore a retrospective and adaptive one, reshaped by each era that needed a Korean name for supreme heaven.
