"... whatsoever proceeds from Them is identical with the truth and conformable to reality."

"Briefly, Bahá’u’lláh says that “He Who is the Dawning-place of God’s Cause” is the manifestation of “He doeth whatsoever He willeth”, that this station is reserved to that sanctified Being, and that others receive no share of this essential perfection. That is, since the essential infallibility of the universal Manifestations of God has been established, whatsoever proceeds from Them is identical with the truth and conformable to reality. They are not under the shadow of the former religion. Whatsoever They say is the utterance of God, and whatsoever They do is a righteous deed, and to no believer is given the right to object; rather must he show forth absolute submission in this regard, for the Manifestation of God acts with consummate wisdom, and human minds may be incapable of grasping the hidden wisdom of certain matters. Therefore, whatsoever the universal Manifestation of God says and does is the very essence of wisdom and conformable to reality."
