September 8

It is important for all those Bahá'ís who are engaged in the academic study of the Bahá'í Faith to address the theoretical problems which undoubtedly exist, while refusing to be distracted by insidious and unscholarly attacks and calumnies which may periodically be injected into their discussions by the ill-intentioned. Discussion with those who sincerely raise problematic issues, whether they be Bahá'ís or not, and whether -- if the latter -- they disagree with Bahá'í teachings, can be beneficial and enlightening. However, to continue dialogue with those who have shown a fixed antagonism to the Faith, and have demonstrated their imperviousness to any ideas other than their own, is usually fruitless and, for the Bahá'ís who take part, can be burdensome and even spiritually corrosive.
