One of the assignments for my second degree is to interview a high priest or priestess. The point of the interview is to get a feel for what it is really like to be a high priestess. What kind of commitment is involved etc. While I have not done my interview yet, I did find a great article today on Witchvox that relates to this. A high priestess wrote out a diary of what her week looks like and what activities she had to do. It is a very enlightening article. I would say that one of the key components of being a high priestess is that you have to have the time to spend helping your coven. You are almost like a mom, in the sense that your Wiccan children come first. You will be in charge of being a teacher, a mentor, and an emotional and spiritual support system for your “children.” It takes a lot of time, commitment, and love to be a high priestess.
