With respect to your inquiry about whether, in the Bahá'í
context, English might possibly be regarded as a language of Revelation, the
House of Justice asks us to explain that, while Shoghi Effendi's translations
of the Writings of Bahá'u'lláh into English carry with them a large measure of
interpretation of the intent and purpose of the Author of the text -- an
interpretation which he, as Interpreter of the Sacred Text, could alone
authoritatively provide -- one should not conclude that the English language
into which the Writings were translated could, therefore, be considered as a
language of Revelation.
