Thealogy views divine matters through feminine perspectives including but not limited to feminism. Valerie Saiving, Isaac Bonewits (1976) and Naomi Goldenberg (1979) introduced the concept as a neologism. Its use then widened to mean all feminine ideas of the sacred, which Charlotte Caron usefully explained in 1993: "reflection on the divine in feminine or feminist terms". By 1996, when Melissa Raphael published Thealogy and Embodiment, the term was well established.

Phillip Emmons Isaac Bonewits was an American Neo-Druid who published a number of books on the subject of Neopaganism and magic. He was a public speaker, liturgist, singer and songwriter, and founder of the Neopagan organizations Ár nDraíocht Féin and the Aquarian Anti-Defamation League. Born in Royal Oak, Michigan, Bonewits had been heavily involved in occultism since the 1960s.
