The Kitab-i-Aqdas appears to allow bigamy. This is explained in Note 17 on page 59 of the "Synopsis and Codification": "The text of the `Kitab-i-Aqdas' upholds monogamy, but as it appears also to permit bigamy, the Guardian was asked for a clarification, and in reply his secretary wrote on his behalf: `Regarding Bahá'í marriage: in the light of the Master's Tablet interpreting the provision in the "Aqdas" on the subject of the plurality of wives, it becomes evident that monogamy alone is permissible, since, as `Abdu'l-Bahá states, bigamy is conditioned upon justice and as justice is impossible, it follows that bigamy is not permissible, and monogamy alone should be practised.'" This is an authoritative interpretation, and as an interpretation states what is intended by the original text, it is correct to say that the Kitab-i-Aqdas prohibits plurality of wives. This method of establishing monogamy as the law of the Faith is one example of the process referred to in the introduction to the "Synopsis and Codification" whereby there is a progressive disclosure of the full meaning of the laws of the Faith as the Dispensation unfolds.
