The "Baha'i state" will function, "in all religious and civil matters, in strict accordance with the laws and ordinances in the Kitab-i-Aqdas".

The Kingdom of Bahá’u’lláh

“With regard to the question about the manner in which the laws of the Universal House of Justice will be enforced on the peoples of the world, this needs to be understood within the context of the gradual evolution of the Faith and the emergence of the world commonwealth. From the extract from "Messages to the Bahá'í World, 1950-1957", p. 155, it is clear that the "Bahá'í state" will function, "in all religious and civil matters, in strict accordance with the laws and ordinances in the Kitab-i-Aqdas, the Most Holy, the Mother-Book of the Bahá’í Revelation".”
