And, now that this all-important Work may suffer no neglect,
but rather function vigorously and continuously in every part of
the Bahá’í world; that the unity of the Cause of Bahá’u’lláh may
remain secure and inviolate, it is of the utmost importance that in
accordance with the explicit text of the Kitáb-i-Aqdas, the Most
Holy Book, in every locality, be it city or hamlet, where the number
of adult (21 years and above) declared believers exceeds nine, a
local “Spiritual Assembly” be forthwith established. To it all local
matters pertaining to the Cause must be directly and immediately
referred for full consultation and decision. The importance, nay
the absolute necessity of these local Assemblies is manifest when
we realize that in the days to come they will evolve into the local
Houses of Justice, and at present provide the firm foundation on
which the structure of the Master’s Will is to be reared in future.
