As to the fundamentals of teaching the Faith: know thou that delivering the Message can be accomplished only through goodly deeds and spiritual attributes, an utterance that is crystal clear and the happiness reflected from the face of that one who is expounding the Teachings.
– Selections from the Writings of `Abdu’l-Bahá, 146.12, p. 183.
Teaching the Bahá’i faith is one of the prerequisites, and yet we’re also not supposed to proselytize. Marshal McLuhan may not have been Bahá’i, but he certainly taught about the nature of media. We do need to be clear in what we say, but notice that most of what ‘Abdu’l-Bahá’s words on the fundamentals of teaching are about the behavior and nature of the teacher.
