The existence of authoritative interpretations does not preclude the individual from engaging in the study of the Teachings and thereby arriving at a personal interpretation or understanding. A clear distinction is, however, drawn in the Bahá’í Writings between authoritative interpretation and the understanding that each individual arrives at from a study of its Teachings. Individual interpretations based on a person's understanding of the Teachings constitute the fruit of man's rational power and may well contribute to a greater comprehension of the Faith. Such views, nevertheless, lack authority. In presenting their personal ideas, individuals are cautioned not to discard the authority of the revealed words, not to deny or contend with the authoritative interpretation, and not to engage in controversy; rather they should offer their thoughts as a contribution to knowledge, making it clear that their views are merely their own.
