The terms priest, priestess, high priest, and high priestess get tossed around a lot, especially in the hellenism community. But oftentimes, there is very little context or explanation on what it means to be the priest/priestess of a god. I think understanding these terms, their duties, and some very frequent misconceptions are once again an important part of this cared for religion. Because despite what many may tend to treat it as hellenic polytheism is a religion. Not one I would consider organized religion today, but a very real and alive religion and should be treated as such.
Naturally this isn't to say you have to strictly adhere to hellenism, your practice and worships will always be your own. But it is an important thing to remember when dealing with the concept of priest/priestesshood.
As usual, this is my own understanding and research of the topic, always be sure to do your own when needed and double check sources! Additionally, from here out I will exclusively be saying "priestess" and "priestesshood" as I am studying and training to be one, but for the most part (excluding the history) it will also apply to priest/priesthood within the modern day religion.
When we talk about modern-day hellenic priestesshood, we can't entirely look at it in its original form in ancient Greece. Back then, priestesshood was a temple station that could be bought by well-off families or something young girls were born into. Girls as young as 7 could be taken into temples on the path of priestesshood, and as they grew older, their ranks/titles within the temple would grow with them. With that said, for the most part priestesses bought their way into the station, having come from financially well-off families. Priestesshood could be seen as an "escape" from the patriarchal household society held at the time, often giving these women significant importance above men. Although how accurate this is, we don't fully know, as young girls would also have been born into a family and encouraged to perform priestly activities at a young age.
These were in the days when our temples stood high and mighty, and the unfortunate truth is that's simply not the case today. That said, hellenism has survived the ages, and we've adopted modern ways of worship, and therefore, priestesshood should be looked at in a similar fashion.
As we today have learned to adapt our worships to modern times while keeping the essence of the gods' importance, priestesshood today has also adapted. While the grand temples from those days are mostly in ruins, we have found ways to construct them in online spaces, and when able, in real life, planned services and congregation. So what does a priestess of a hellenic god do today?
To become the priestess of a god is something I would consider a "full-time devotee." Someone whose life is tasked with acts of devotion in that god's name and honor. A priestess of Aphrodite might become one of her sacred whores or a matchmaker, a priestess of Demeter may live rurally and grow crops to provide and offer, a priestess of Hades may become a death worker (PLEASE heavily research that topic itself if it is a path you choose as not everyone can become one and it is considered a closed practice by degrees) or a baneful worker, etc. Regardless of the gods, a priestess would typically perform duties that align with that god's attributes and associations. It is a dedication to serving that god and performing acts in their name and honor. Priestesshood is a commitment to that god.
How Do You Become a Priestess?
This can be a difficult question to answer. As stated before, priestesshood could be bought or be something you were raised into. However, in our modern day, that's no longer the case. From what I've researched, priestesshood can be obtained through two methods.
Mentorship under an established priestess
An invitation from the god
Mentorship would entail finding a god's priestess and them taking you under their wing and training you personally. Many times, the mentorship will be something paid for, but will give you someone experienced and a solid learning foundation in your future training. Naturally, you should vet the priestess beforehand and ensure they are someone trustworthy and knowledgeable. There are many people who will falsely claim priestesshood, so ensure this is someone truthful in their dedication.
On the opposite end of the spectrum, someone can personally be invited by their god into priestesshood. This in itself can hold a myriad of difficulties, such as initial uncertainty. A lot of divination or fact-checking would be required as well as checking in with that god themself. Another difficulty would be the need to do training on your own. There is no step by step guide for priestesshood for each and every god, and the chances of finding a genuine one for your deity is slim. Training solo would mean researching and practicing on your own, with a great deal of trial and error and constant check-ins with your god.
My path to priestesshood started from an invitation from Hermes, and it took a lot of communication and readings with him to gain true confidence in the decision. It can be confusing, and navigating the path alone can be incredibly scary and difficult.
Can You Become a High Priestess?
A high priestess is a vastly higher title than a normal priestess, and one that, in my opinion, very few can hold. A high priestess's entire life would be spent dedicating themself to that god, continuously in prayer and doing their duties. This is a 24/7 commitment and a lot of the time entails leaving your worldy self behind (including families, friends, ect) to live in dedication for their god. They channel the very essence of their god.
A high priestess is far more than a title, it is the pinnacle of dedication to a god and is not an easy title to obtain. A high priestess's life would entirely belong to that god, and they would spend every possible moment of it channeling the essence of that god through prayers and worship and dedicating acts for the community they have.
It is not a role just anyone can take on, and I highly advise much deeper research into the understanding of that role and what it means/entails.
Common Questions and Misconceptions
So a priestess is just a normal follower?
Not particularly. A priestess would be required to do their devotional duties that align with their station. Priestesses would be leaders, conducting rituals and serving as a conduit for their god. There is a difference between devotional acts and devotional duties, the fine line being whether these devotions were optional or not.
I've only been working with [insert god] for a short amount of time, can I become a priestess?
The gods don't care about how long you've been in service to them. What they look at is devotion and knowledge. So long as you're willing to put in the work and truly dedicated yourself to the role, it doesn't matter if you've been a devotee for 5 years or 5 days. That said, please make sure this is a path you truly wish to walk. It is a very serious role, and the gods won't take kindly to it being treated like a game or an experiment.
I'm still a minor, can I become a priestess?
While in ancient times priestesses would be trained as young as 7, they wouldn't be considered priestesses until they reached the marriage age of 14. So by account, yes, absolutely. But I think it's important to spend your younger years truly studying and gaining knowledge and experience with your god and being certain that this is a path you wish to take. Don't be swayed by social media and other's recounting. Take your time.
But [insert creator] said they're a high priestess!
Are they always on social media? Are they constantly posting? Do they have a large online presence that they manage on their own? Then chances are, they're not a high priestess. A high priestess has no time for these things unless someone else is managing it for them to show what the life of a high priestess is like.
Would a high priestess be an oracle?
While a high priestess can be an oracle and vice versa, the two are not inherently synonymous. I'll make a long post on oracles once I've researched them more but from my current understanding, yes and no.
