Modern revivalist or reconstructionist Hellenic polytheism exists in several forms, both in Greece and in other countries. There are no standardized naming practices for this religion, and individual practitioners and groups use a variety of names, often reflecting subtle differences in belief or practice. The Greek organization YSEE (Ύπατο Συμβούλιο των Ελλήνων Εθνικών, Supreme Council of Ethnikoi Hellenes) refers to the religion as the "Ethnic Polytheistic, Hellenic Tradition", or simply "Hellenism", and its practitioners as "Ethnikoi Hellenes". Another Greek organization, Dodekatheon (Δωδεκάθεον, Dōdekátheon), uses the term ἑλληνικὴ θρησκεία (hellēnikē thrēskeîa, translated as "Hellenic religion"). A third, the Helliniki Hetaireia Archaiophilon (Societas Hellenica Antiquariorum), prefers the phrase, "traditional Hellenic religion of the Dodecatheon".
The US-based organization Hellenion uses the term "Hellenismos" (Ἑλληνισμός, Hellēnismós). This term, corresponding to the English word Hellenism, meant (in ancient Greek) the civilization and culture of ancient Greece, and is used in modern Greek to refer to the totality of the Greek people and culture. The term's use in religion stems from a systemization of Greek Religion done by the Roman Emperor Julian. Its use to refer to modern revivalist Hellenic polytheism was popularized by Andrew Campbell, Hellenion's founder and the author of Old Stones, New Temples. [6] Another American group, Elaion, uses the term "Dodekatheism" (Greek: δώδεκα, dodeka, "twelve" + θεϊσμός, theïsmós, "belief in the gods"). "Hellenic Paganism" is frequently used, most notably on the HellenicPagan mailing list, which at over 400 members is the largest English-language discussion group for Hellenic polytheists. However, some Hellenic polytheists, such as the members of YSEE ([7]), object to the use of the word "Pagan" to characterize their religious practices because of the term's origin as an insult.
Other terms in common usage by revivalist Hellenic polytheists include "Hellenic" or "Greek reconstructionism" and "Hellenic Traditionalism"
