[First Presidency, Letter to Maud Heder]
[Regarding an earlier First Presidency] letter [which] was addressed to you for the purpose of satisfying you that your pretended marriage with exbishop Samuel J. Robinson of Colonia Dublan was illegal and unlawful for the reason that the party, whoever he was, that performed the marriage ceremony did so without authority, and therefore it was in fact as if no marriage ceremony had been performed at all. We stated this in substance in our former letter to you. ... Now, dear sister, we repeat for your own satisfaction that inasmuch as this pretended marriage ceremony, which was performed not behalf of yourself and ex-Bishop Robinson, was without authority, and besides, in direct opposition to the stand which the Church had taken in regard to plural marriages, it was as though no ceremony had been performed at all, and is therefore null and void, and you are entirely free to enter into legitimate marriage relations with whomever you may choose.
