The Prophet revealed the principle of celestial marriage, instructing the apostles that marriage was not just until ‘death do you part,’ but ‘for time and all eternity.’ Included in the revelation was the instruction to practice polygamy (to marry more than one wife). John said, “I had always entertained strict ideas of virtue, and I felt as a married man that this was to me, outside of this principle, an appalling thing to do. Hence, nothing but a knowledge of . . . the revelations of God . . . could have induced me to embrace such a principle.” Reluctantly John obeyed the Prophet and entered into the practice.
