The Hierophant card has so many Popish trappings that it is sometimes hard for readers to like him, or interpret him as positive rather than seeing his potential for being unreasonable, hide-bound, literal and stodgy. I like to point out the decks where the Hierophant is the Oracle at Delphi or some other less loaded image.
When the Hierophant appears as a person, he’s likely an old, favored teacher, therapist, counsellor, advisor, or sponsor. That young Priest with progressive ideas, or the old Rabbi who was always so down to earth and fun, or maybe an uncle who always offered such common sense advice. Unfortunately, he can also represent that nasty teacher the Querent is dealing with, the one who refuses to deviate from the text book, or a sour-faced elder who wants to keep the church old fashioned and in the dark ages.
