POLYGAMY
In using the term "polygamy" in reference to the principle that was taught and practiced by the Saints, I desire it distinctly understood that I use it in the sense of a man having more than one wife. Polygamy, in the sense of plurality of husbands and of wives never was practiced in the Church of Jesus Christ of Latter-day Saints in Utah or elsewhere; but Celestial marriage—including a plurality of wives—was introduced by the Prophet Joseph Smith and was practiced more generally by the saints under the administration of President Brigham Young.
You say that you have no evidence that those men, viz. Lyman Wight, James J. Strang, Gladden Bishop, William Smith and others that I mentioned to you "practiced polygamy" before plural marriage was "introduced" (as claimed by you) by Brigham Young. You said polygamy was "introduced" eight years after the Prophet's death by Brigham Young. If so, then why did these men practice it before that time? I was satisfied that you would not exert yourself in seeking for this knowledge and tried to help you find the information.
