...we cannot be sure how much or how little of the four Gospels are accurate and include the words of Christ and His undiluted teachings, all we can be sure of, as Bahá'ís, is that what has been quoted by Bahá'u'lláh and the Master must be absolutely authentic. As many times passages in the Gospel of St. John are quoted we may assume that it is his Gospel and much of it accurate. (23 January 1944 to an individual believer on Behalf of the Guardian)
