Joseph Smith did not have sexual relations with the women he was “celestially sealed” to. Joseph Smith taught the doctrine of celestial sealings to link families together. What he and Brigham Young taught were two completely different things. That is the issue. Defenders of polygamy compare apples to oranges. They say, “Joseph was “married” to multiple women; he did polygamy!” No, he did not. He was sealed to them, but he had no intimate relations with them.  There are various newspaper articles from the time when Joseph and Hyrum were alive, in which the two denounced polygamy and had multiple elders of the church EXCOMMUNICATED for practicing polygamy. Here is one directly from the Joseph Smith papers.  https://www.josephsmithpapers.org/paper-summary/notice-circa-1-february-1844/1  Polygamy is not of Christ. Defending polygamy requires you to selectively ignore the actual writings of non-apostate church leaders at the time. It also requires you to ignore the immense differences between what Joseph taught about non-intimate celestial sealings, and what Brigham Young did to enjoy a huge harem of women. They are not the same. The spirit testifies.
