“Pagan” and “Neo-Pagan” are capitalized herein where they refer to the contemporary Pagan and Neo-Pagan religious communities. The words should be capitalized when used as nouns or adjectives in the same way that “Christian”, “Catholic”, “Mormon”, “Hindu”, “Buddhist”, and so on, are capitalized.
Where “pagan” is not capitalized herein, it refers to ancient pagans predating the modern era, like the ancient Celts, Egyptians, and Norse. When “neo-pagan” is not capitalized herein, it refers to modern neo-pagan movements, distinct from contemporary Neo-Paganism, like the German Volkisch movement of the early 20th century.
“Neo-Paganism” is sometimes written without the hyphen (i.e., “Neopaganism”). There is no substantive difference between the two words.
