You are confusing the Church of Satan (actual Satanists and mythology) with the Satanic Temple.

With unfortunate regularity - and much to our chagrin - The Satanic Temple is confused with an earlier organization, the Church of Satan, founded by Anton Szandor LaVey in the 1960s.

The Satanic Temple is a non-theistic organization…

…the group views Satan neither as a supernatural being, nor a symbol of evil, but instead relies on the literary Satan as a symbol representing “the eternal rebel” against arbitrary authority and social norms, or as a metaphor to promote pragmatic skepticism, rational reciprocity, personal autonomy, and curiosity.
