As a practicing High Priestess, I can only tell you what it means to me.
I was taught that every woman practitioner following a pagan path is a Priestess, the one who leads them in Ritual is a High Priestess.
When I first found my pagan path, I dedicated myself and started learning, from family members, from my shaman, from mentors, from personal study and from life. I was considered a Priestess when I started preforming Rites and Rituals. As a solitary Witch I started creating and writing spells, rites & rituals of my own. Eventually I was in a position to work with others and as my circle came together I was chosen as High Priestess. With that title came more responsibility, for teaching, organising and mentoring.
Then as that circle expanded members of the group "hived off" and when I moved from the area two more "hives" were created, I now have a fourth circle, here in my new home and can rightly claim the title if Witch Queen. I am still an active High Priestess, and I am still learning all that means.
High Priestess of Soul was created in 1965.

There are many high priestesses in Wicca, including Vivianne Crowley, who was one of the most notable.
In Greek mythology, Apollo's priestess is known as the Pythia or Oracle of Delphi. The Pythia was a high priestess who delivered prophecies and advice in the temple of Apollo at Delphi. She would enter a trance-like state to communicate the messages from the god Apollo to those seeking guidance.
