Three women testify that Assistant President John C. Bennett and Apostle William Smith taught them that Smith approved of "spiritual wifery" wherein several men have sexual relations with the same woman. The women testifying were Margaret and Matilda Nyman and Catherine Fuller Warren. The report of the Nymans was later printed in the 29 May 1844 Nauvoo Neighbor. The sisters said that Elder Chauncy Higbee had advised them that Smith approved of "spiritual wifery" but gave instructions to keep the matter a secret because "there was no sin when there is no accuser." Catherine Fuller Warren in her 20 May 1842 testimony responded to charges of "unchaste and unvirtuous conduct with John C. Bennett and others" by admitting to having intercourse not only with him but with Chauncy Higbee and the prophet's younger brother, Apostle William Smith. Speaking in her defense, however, she insisted that the men had "taught the doctrine that it was right to have free intercourse with women and that the heads of the Church also taught and practised it which things caused her to be led away thinking it to be right." Three women testify that Smith taught "spiritual wifery".
