As regards the membership of the International House of Justice, ‘Abdu’lBahá 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’lBahá 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.
