The Hierophant is a person who brings religious congregants in touch with that which is holy. He represents having a belief system, sharing a cultural heritage, honouring ritual and ceremony, following a discipline.
Though the Hierophant is a religious leader, this card is not about religion or spirituality, since there are other cards that address those themes adequately. This card is about unity with a congregation, belonging to a group, identification with a traditional heritage, subculture, or national identity. This card prompts the questioner to follow rules, take an orthodox approach. It's also about joining or acting as a group, feeling loyalty, and being in an institutionalized setting, committed to a cause.
