My piece on Mormons led to discussions elsewhere. One Mormon asserted that LDS Church still practices polygamy because if an eternally sealed wife dies, her widowed husband may marry another wife in eternal sealing, which gives him two wives in the next world. Another Mormon said that all Churches practice polygamy then, since they all marry widows and widowers.
Well, no. Marriage in all other churches is for this life only. "Til death us do part" means that death ends the marriage. Which made me realize that there are only single people in heaven!
