The Church of the Highest Supreme (太上会 Tàishànghuì; or "Most Supreme", "Most High"; also known as 太上门 Tàishàngmén, the "Gate of the Highest Supreme") is a Chinese folk religious sect of northern China. The origins of the sect are obscure, although Thomas David Dubois traces it to the theological tradition of the networks of Hongyangism (弘阳教), another northern folk religious sect which has been officially registered under the auspices of the Chinese Taoist Association since the 1990s.Goossaert, Palmer. 2011. p. 347, quote: «[Since the 1990s] [...] a number of [...] lay salvationist groups (such as Xiantiandao in southern China and Hongyangism [弘阳教 Hóngyáng jiào] in Hebei) also successfully registered with the Taoist association, thus gaining legitimacy».
