Truth?

So, there's a bit of a discussion on absolute truth, so I thought I'd throw in my two cents worth. I found this one quotation in Some Answered Questions:
Briefly, it is said that the "Dayspring of Revelation" is the manifestation of these words, "He doeth whatsoever He willeth"; this condition is peculiar to that Holy Being, and others have no share of this essential perfection. That is to say, that as the supreme Manifestations certainly possess essential infallibility, therefore whatever emanates from Them is identical with the truth, and conformable to reality. They are not under the shadow of the former laws. Whatever They say is the word of God, and whatever They perform is an upright action. No believer has any right to criticize; his condition must be one of absolute submission, for the Manifestation arises with perfect wisdom -- so that whatever the supreme Manifestation says and does is absolute wisdom, and is in accordance with reality. (Abdu'l-Baha, Some Answered Questions, p. 173)

So, the "Dayspring of Revelation" is another title for a Manifestation of God. "Manifestation of God" is the term used in the Baha'i Writings for Moses, Christ, Muhammad, the Bab, and Baha'u'llah. (Note that Abdu'l-Baha is not a Manifestation of God. He was the son of Baha'u'llah. Baha'u'llah appointed Abdu'l-Baha (which means Servant of Baha) as His successor and Interpreter of His Writings and the Perfect Exemplar of His teachings.)
He continues...
In short, the meaning of "He doeth whatsoever He willeth" is that if the Manifestation says something, or gives a command, or performs an action, and believers do not understand its wisdom, they still ought not to oppose it by a single thought, seeking to know why He spoke so, or why He did such a thing. The other souls who are under the shadow of the supreme Manifestations are submissive to the commandments of the Law of God, and are not to deviate as much as a hairsbreadth from it; they must conform their acts and words to the Law of God. If they do deviate from it, they will be held responsible and reproved in the presence of God. It is certain that they have no share in the permission "He doeth whatsoever He willeth," for this condition is peculiar to the supreme Manifestations.
So Christ -- may my spirit be sacrificed to Him! -- was the manifestation of these words, "He doeth whatsoever He willeth," but the disciples were not partakers of this condition; for as they were under the shadow of Christ, they could not deviate from His command and will.
