Hiereis Studies Program

Mt Nysa offers the Hiereis Studies Program for adult individuals (18+) who wish to serve the Gods of Ancient Hellenic Religion, with a particular focus on mystery cult and associated deities.

The English words priest and priestess – related to the Greek πρεσβύτερος (presbúteros; elder) – are imperfect translations of a variety of sacred specialists in the Ancient Hellenic Religion. Most often, these specialists were not pastoral leaders in the modern clerical sense, but ritual experts known as an ἱερεύς (hiereús; masculine) or ἱέρεια (hiéreia; feminine). These words in turn come from the Greek ἱερός (hierós; sacred, consecrated in the ritual context), and can be translated literally as “man/woman of the sacred [ritual things]". A better translation for today might be "ritual specialist".

Note: Hiereis is the plural form of hiereus; within the context of Mt Nysa and this Program, it is employed as a gender neutral term. The same is true of priest/priesthood, though less often used. We also recognise a third, gender-neutral term: hierophoros, which some of our non-binary students have opted to train and consecrate under.

Our approach

The Hiereus then and now

Any individual in a state of purity may perform rituals in Ancient Hellenic Religion; clergy has never been required for this. Hiereis were an extension of the community and dedicated representatives of it (to the Theoi, Gods), often facilitating festivals, rites of passage, and specialised rites of purification. Most importantly, they maintained and promoted the cult of their deity (including care of the sanctuary and cult images). In the ancient Hellenic world, an individual could become a sacred official by appointment, election, lot, inheritance, or even purchase. It did not require a specific training, personal calling, or spiritual gift, but was civic in nature – though certain attributes could set apart a good hiereus (generosity, piety, and so on). As we cannot (and do not wish to) replicate the societal structures of Archaic-Classical Greece, there is no straightforward process for becoming a modern Hellenic priest or priestess. 

Our Program offers an adapted yet authentic pathway for priesthood based on intensive study and communal appointment, rooted in the legacy of the hiereus/hiereia. The first set of modules,  Foundations of Hiereis Studies, comprises of advanced education in the system of Ancient Hellenic Religion, particularly ritual form and function, complemented by study of language, ethics, theology, and cosmological principles. In the second set of modules, Specialisation and Cultic Formation, candidates specialise in the traditions of 1-2 deities (we focus on mystery deities, or those associated with mystery cult), researching their origins, hymns, mythologies, festivals, epithets, sanctuaries, cultic regulations, and associated mysteries. Rather than attempting to reconstruct one particular cult from fragmented historical sources, candidates are encouraged to survey many cults of the deity to form a new and localised tradition.

Upon completion of the Program, candidates and their assignments will be put forward to the Mt Nysa community for consideration. Should their appointment be confirmed by two independent divinations, they will be consecrated as an Hiereus, Hiereia, or Hierophoros and recognised as a ritual specialist by Mt Nysa. See more on this process below. From there, Hiereis may form temples and/or lead communities as they feel called without oversight or regulation, beyond the local and federal laws of their land. In most places, they are eligible for ordained status and can legally officiate weddings and funeral services.



curriculum and tuition

Studying with mt nysa

The Hiereis Studies Program requires demanding reading of primary source and secondary scholarship in the English language, with consideration of ancient literature, non-literary texts, and material culture. In addition, 10 hours of Ancient Greek language instruction are required for completion of the Program. Prior knowledge of Ancient Greek is not required; we supply textbooks and 10 hours of video lessons to understand the language at an introductory level (proficiency in alphabet, Classical pronunciation, transliteration, basic vocabulary and grammar), and offer a free monthly study group to facilitate language learning. Hiereis Studies students are also encouraged to supplement their education with free monthly lectures offered through Mt Nysa on the first Sunday of each month.

All instruction and reading materials are provided as part of the Program, organised by module in PDF form. Sacred tools and objects (hiera) will be encouraged to procure. Many of these can be made or sourced from low-cost sources, such as thrift stores.

The Hiereis Studies Program is made up of ten core modules. Each module comprises of university-level reading as well as reflective and practical assignments.

Part One: Foundations of Hiereis Studies
  1. Priests and Priesthood in Ancient Greece
  2. Concepts of Sacrifice and the Sacred
  3. Protection, Pollution, and Purification
  4. Theologies and Ethics for the Practicing Hiereus

Part Two: Deity Specialisation and Cultic Formation
  1. Origins, Hymns, and Mythology
  2. Historical Cults and Sanctuaries
  3. Festival Cycles and Calendars
  4. Rites of Passage: Birth and Death, Coming of Age and Marriage
  5. Specialised Rites, Mysteries, and Hiera
  6. Practicum (record of facilitation of two public rituals or festivals) and Capstone Project (2500 word essay or specialised ritual script). This will be submitted for completion of Program along with Book of Ritual, Bibliography, and record of 10 hours of Ancient Greek language study. Detailed instructions will be provided regarding the fulfillment of these requirements.

Part One of the Program is taught live on Zoom the second Sunday of every month for 4 months. All modules and assignments must be successfully completed before moving onto the next part of the Program.

Part Two of the Program is self-paced, with materials provided for individual specialisation and a check-in session (Zoom or email) each module with Program instructor. This part of the Program is designed for 6 months of study, but candidates may move more quickly or take up to 18 months to complete.

Tuition for the Hiereis Studies Program is offered on a sliding scale from $50-$100 USD per module. Two full scholarships are offered each enrollment cycle for students who demonstrate extraordinary financial need and merit. As of 22 Janunary: All scholarships have been awarded for the March 2026 cycle.

Candidates are not obligated to continue their studies after Part One of the Program, and may otherwise choose to end their studies at any time. If a candidate leaves the Program early, they will not be charged for additional modules. Please note that no refunds can be given on modules already distributed, begun, or completed.

The above curriculum and requirements are only applicable for students beginning the Program after January 2026.



what comes next?

Confirmation process

Upon successful completion of all ten modules, candidates forward their collected assignments in a Book of Ritual to the Hieropoioi (council overseeing sacred appointments). These Hiereis are experienced members of Mt Nysa who volunteer to review candidate assignments, perform inductive divinations to confirm divine approval of the appointment (2 required), and witness the oath and consecration ceremony of new Hiereis.

What if the divinations are not favorable?! I knew you’d ask! If a candidate has successfully completed the ten modules, we assume a certain level of maturity in their knowledge, practice, kharis with the Theoi and discernment in becoming a ritual specialist. This process is not intended to gatekeep consecration, but to provide communal feedback, recognition, and final confirmation. Two divinations are required as they can ensure neutrality and inform one another (e.g.: Divination #1 has an unfavorable or ambiguous outcome; Divination #2 offers context, such as advising the candidate to wait another month or perform a particular sacrifice).

Following consecration, candidates are recognised as Hiereis by Mt Nysa. They may go on to found their own temples, religious organisations, services or educational offerings as they feel called, though primary focus should be on the formation and maintenance of the deity’s cult in their local community.

"Who organises this program? What are your qualifications?"

No one individual or group was responsible for initiating sacred officials in the ancient world. This is why we have adapted an appointment process in our small-scale way. As for the founder behind this collective “we,” my name is Bria Melitta and “I am no-one special” (to echo the late Kallímakhos of Hellenicgods.org). I am a lifelong student, teacher, mother, and devotee of the Theoi. I pursued Religious Studies in undergraduate school and soon after discovered my ancient Mediterranean matrilineage. The path has been unfolding ever since.

My interest in formal priesthood began in 2020 after certifying as a doula (childbirth attendant) under some incredibly wise women. Amidst long hours sifting laboring mothers' hips with scarves, gentle hymns and herbs for fertility and candlelit women’s circles, I came to recognise the great hunger that people have for ancient spiritual guidance in life’s transitions. Under the mentorship of Yeshe Meryemana Matthews of Mt Shasta Goddess Temple, I undertook a rigorous 2-year training as a holy woman and was consecrated as a priestess of Aphrodite Kubileya in 2023. In 2023, I also founded the Mt Nysa Mystery School dedicated to the study and revival of Dionysian and Demetrian Mysteries. In 2025 I was awarded a MA With Distinction in Classical Mediterranean History and Archaeology from the University of Leicester. The cliché rings true—the more I learn, the less I know. How exciting it is!

I am an ordained member of clergy but have no desire to be the authority over others, only to share this rich ancestral tradition in a way that’s, well, not so overwhelming. This humble program should not be thought of as the pathway to Hellenic priesthood but a pathway. It is certainly not the only place you can find education. We focus on the priesthoods of mystery deities, but should you be more generally-inclined, we may have other organisation recommendations.

However you make your way—do make it! I am of the opinion that the more holy men and women we have, the more dedicated cults of the Theoi we revive, the better. We can each do our part to give as much as we take, to repair the threads of the cosmic tapestry, to step inside the mystery of the kykeon and the thyrsos. In doing so we greatly honor the Theoi, help to heal Ge (Earth) and all beings who call Ge their home.
