Was any Vulcan ever called a Priest or Priestess?
In one Voyager episode, Tuvok's wife sent him this message:
My husband, we have been given the news that you are alive. Your children and I have asked the priests at the temple of Amonak to say prayers for your safe return.
Royalty and religion both seem to conflict with the Vulcan adherence to logic and non-emotion.
There are references to Vulcan religion in different series, Roddenberry's own novelization of TMP in one chapter talks about it.
As for the existence of royalty, the Vulcans are presented as a very traditional people.
