Mystagogue

A mystagogue (from Greek:μυσταγωγός "person who initiates into mysteries") is a person who initiates others into mystic beliefs, an educator or person who has knowledge of the sacred mysteries. Another word is hierophant.

In ancient mystery religions, a mystagogue would be responsible for leading an initiate into the secret teachings and rituals of the cultus. The initiate would often be blindfolded, and the mystagogue would literally "guide" him into the sacred space.
