Dear Baha'i friend,
Your recent letter, in which you share with us the questions that have occurred to some of the youth in studying "The Dispensation of Baha'u'llah," has been carefully considered, and we feel that we should comment both on the particular passage you mention and on a related passage in the same work, because both bear on the relationship between the Guardianship and the Universal House of Justice.
The first passage concerns the Guardian's duty to insist upon a reconsideration by his fellow members in the Universal House of Justice of any enactment which he believes conflicts with the meaning and departs from the spirit of the Sacred Writings. The second passage concerns the infallibility of the Universal House of Justice without the Guardian, namely Shoghi Effendi's statement that "Without such an institution [the Guardianship] ... the necessary guidance to define the sphere of the legislative action of its elected representatives would be totally withdrawn."
Some of the youth, you indicate, were puzzled as to how to reconcile the former of these two passages with such statements as that in the Will of 'Abdu'l-Baha which affirms that the Universal House of Justice is "freed from all error."
Just as the Will and Testament of 'Abdu'l-Baha does not in any way contradict the Kitab-i-Aqdas but, in the Guardian's words, "confirms, supplements, and correlates the provisions of the Aqdas," so the writings of the Guardian contradict neither the revealed Word nor the interpretations of the Master. In attempting to understand the Writings, therefore, one must first realize that there is and can be no real contradiction in them, and in the light of this we can confidently seek the unity of meaning which they contain.
