More broadly, Hellenism centers itself around the worship of Hellenic deities, namely the twelve Olympians.[3]
Greeks that identify their religion and way of life with Hellenism are commonly referred to as Ethnikoi Hellenes, "Ethnic Hellenes". Non-Greek devotees of the Greek gods and emulators of Hellenic ideals found in Hellenism are commonly referred to as Hellenists. More generally, someone who worships the Greek gods but does not necessarily adhere to Hellenic ideals, ethos or ritual may be referred as a polytheist or pagan. Pagan and Paganism are insulting terms to use when referring to Ethnic Hellenes and Hellenic Ethnic Religion respectively.
