Theomachist
Theomachist is a term used to refer to an individual who resists God or the divine will. The term comes from the Greek words theos, meaning God and machē, meaning battle. Karl Marx was considered by many to be a theomachist. The atheists who established the Cult of Reason in Revolutionary France have also been described with this term.
