While gathered together, the delegates are a consultative and advisory body whose recommendations are to be carefully considered by the members of the elected National Spiritual Assembly....
The relation of the National Spiritual Assembly to the local Spiritual Assemblies and to the body of the believers in the country is thus defined in the letters of the Guardian of the Cause: Regarding the establishment of "National Assemblies," it is of vital importance that in every country, where the conditions are favorable and the number of the friends has grown and reached a considerable size ...

that a "National Spiritual Assembly" be immediately established, representative of the friends throughout that country.
Its immediate purpose is to stimulate, unify and coordinate by frequent personal consultations, the manifold activities of the friends as well as the local Assemblies; and by keeping in close and constant touch with the Holy Land, initiate measures, and direct in general the affairs of the Cause in that country.
It serves also another purpose, no less essential than the first, as in the course of time it shall evolve into the National House of Justice (referred to in 'Abdu'l-Baha's Will as the "secondary House of Justice"), which according to the explicit text of the Testament will have, in conjunction with the other National Assemblies throughout the Baha'i world, to elect directly the members of the International House of Justice, that Supreme Council that will guide, organize and unify the affairs of the Movement throughout the world....
This National Spiritual Assembly, which, pending the establishment of the Universal House of Justice, will have to be re-elected once a year, obviously assumes grave responsibilities, for it has to exercise full authority over all the local Assemblies in its province, and will have to direct the activities of the friends, guard vigilantly the Cause of God, and control and supervise the affairs of the Movement in general.
Vital issues, affecting the interests of the Cause in that country such as the matter of translation and publication, the Ma_sh_riqu'l-A_dh_kar, the Teaching Work, and other similar matters that stand distinct from strictly local affairs, must be under the full jurisdiction of the National Assembly.
It will have to refer each of these questions, even as the local Assemblies, to a special Committee, to be elected by the members of the National Spiritual Assembly, from among all the friends in that country, which will bear to it the same relation as the local committees bear to their respective local Assemblies.
With it, too, rests the decision whether a certain point at issue is strictly local in its nature, and should be reserved for the consideration and decision of the local Assembly, or whether it should fall under its own province and be regarded as a matter which ought to receive its special attention....
...

it is bounden duty, in the interest of the Cause we all love and serve, of the members of the incoming National Assembly, once elected by the delegates at Convention time, to seek and have the utmost regard, individually as well as collectively, for the advice, the considered opinion and the true sentiments of the assembled delegates.

Banishing every vestige of secrecy, of undue reticence, of dictatorial aloofness, from their midst, they should radiantly and abundantly unfold to the eyes of the delegates, by whom they are elected, their plans, their hopes, and their cares.
They should familiarize the delegates with the various matters that will have to be considered in the current year, and calmly and conscientiously study and weigh the opinions and judgments of the delegates.

The newly elected National Assembly, during the few days when the Convention is in session and after the dispersal of the delegates, should seek ways and means to cultivate understanding, facilitate and maintain the exchange of views, deepen confidence, and vindicate by every tangible evidence their one desire to serve and advance the common weal....
The National Spiritual Assembly, however, in view of the unavoidable limitations imposed upon the convening of frequent and long-standing sessions of the Convention, will have to retain in its hands the final decision on all matters that affect the interests of the Cause ...
