"It is true that should a believer read the writings of Covenant-breakers or enemies of the Cause and permit these words to instill doubts about the truth of Bahá'u'lláh's Cause such a believer would then be considered as having been infected by the poison of Covenant-breaking. However, since you returned the book to your local library upon being informed of the true nature of its contents and told your District Teaching Committee and your National Spiritual Assembly about the matter, it is clear that you took the correct steps and should therefore, with complete confidence, turn to Bahá'u'lláh for protection and guidance, fully assured that His promise to assist those who turn to Him will be fulfilled."

(From a letter dated 29 March 1977 to an individual believer)
