“The word “occultism” comes from a Latin word which means “to hide”, it has reference to the hidden type of activity, to that which is concealed from knowledge, from observation, from light which is at war with law. The occult, therefore, because it is the hidden, the disguised, the secretive, that which works in hostility to law and order and light, is by its very nature the enthronement of man’s will against God’s will, it fosters opposition which is heathenism and idolatry.”

— R. J. Rushdoony
