Hi Godzilla,
Martin Harris and Oliver Cowdery after leaving the LDS Church were rebaptized later in life. Significantly, no witness, even after leaving the Church, recanted the testimonies they had given.
These witnesses are a proof system that God has provided to the world for the truthfulness of the Book of Mormon.
Best to you,
Normandy
Point of fact - Cowdery’s funeral was conducted by a Methodist church and not the Mormon church. Many others believe Cowdery rejoined was the hope that he could convince the saints to abandon polygamy which he was strongly against.
Harris was destitute at the time and mormons paid for him to come to utah after Harris worked for the Strangeites, Whitmerites, Gladdenites, Williamites, and Shakers with the same zeal he did mormonites.
As a ‘witness’ to the truthfulness, one would have to accept equally the ‘truthfulness’ of the Strangeites, Whitmerites, Gladdenites, Williamites, and Shakers on the same level as mormonism as well. I doubt you as a mormon would do that, thus he stands condemned by his own associates.
Testimonies of others who knew these men further point to their lack of character and lack of integrity. If this is the best the mormon world can do - it fails epically.
