Hellenion is a Hellenic polytheist organization that began online with the intent of drawing together the classical pagan community to promote fellowship, free exchange of ideas, scholarship and spirituality.
Hellenion is an US-based religious organization ("church").
They approach Hellenic religion from the reconstructionist perspective, which includes both an emphasis on historical precedent and respect for personal spiritual inspiration. They offer local congregations, study opportunities, and fellowship for those who worship the Olympians and the other deities of ancient Greece in a traditional way. Their mission statement is entitled "What We Mean by Hellenic Pagan Reconstructionism". It is based on a similar statement from another reconstructionist organization devoted to ancient Celtic studies called IMBAS which is no longer active, but established a useful model.
