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, such as America, Great Britain and Germany, 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-Bahá’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 Bahá’í 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.
