January 29

The Lord hath ordained that in every city a House of Justice be established wherein shall gather counsellors to the number of Baha, and should it exceed this number it does not matter. It behoveth them to be the trusted ones of the Merciful among men and to regard themselves as the guardians appointed of God for all that dwell on earth.... 
(Bahá'u'lláh, cited in a letter dated 5 March 1922 written by Shoghi Effendi to the National Spiritual Assembly of the Bahá'ís of the United States and Canada, published in ‘Bahá'í Administration: Selected Messages 1922-1932’; The Compilation of Compilations, Vol. II, The Local Spiritual Assembly)
