Baha'i authorities shield Western believers by not providing translations...

June 6. On this date in 2013, the Universal House of Justice sent an email to an individual believer concerning the number of texts written by the Báb, Bahá’u’lláh, 'Abdu’l-Bahá, and Shoghi Effendi, noting "A fraction of the total numbers of unique works have been published in the original languages or translated into Western languages."

The Kitáb-i-Aqdas, the central book of the Bahá'í Faith written by Bahá'u'lláh, was only officially translated into English in 1992, by which time other translations, such as one by the Royal Asiatic Society, were becoming increasingly available through dissemination via the internet. My personal opinion is that the material in the Kitáb-i-Aqdas is so objectionable that the Bahá'í authorities wished to shield Western believers from its contents, as they do from Bahá'u'lláh's other works by not providing translations.
