You have also asked for an explanation of why, in view of the Bahá’í principle of equality of men and women, women are not allowed to serve on the Universal House of Justice. We share with you the following passages about this subject, taken from letters written on behalf of the beloved Guardian to a National Spiritual Assembly and to an individual believer.
“As regards the membership of the International House of Justice, ‘Abdu’l‑Bahá states in a Tablet that it is confined to men, and that the wisdom of it will be revealed as manifest as the sun in the future. In any case the believers should know that, as ‘Abdu’l‑Bahá Himself has explicitly stated that sexes are equal except in some cases, the exclusion of women from the International House of Justice should not be surprising. From the fact that there is no equality of functions between the sexes one should not, however, infer that either sex is inherently superior or inferior to the other, or that they are unequal in their rights.” —14 December 1940
“Regarding your question, the Master said the wisdom of having no women on the International House of Justice would become manifest in the future. We have no other indication than this.” —17 September 1952
We must always remember Bahá’u’lláh’s exhortation, which is quoted on page 22 of the Synopsis and Codification: “Weigh not the Book of God with such standards and sciences as are current amongst you, for the Book itself is the unerring balance established amongst men. In this most perfect balance whatsoever the peoples and kindreds of the earth possess must be weighed, while the measure of its weight should be tested according to its own standard, did ye but know it.”
