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.
