Career
By July 1837, he estimated that he had "traveled 544 miles and preached forty-three sermons." After Smith"s martyrdom in 1844 precipitated a succession crisis in the church, Post initially demurred from affiliating with any of the resulting sects, instead continuing to preach as an independent believer. Rigdon had briefly led his own church following Smith"s martyrdom, but it had collapsed in 1848. In 1871, Post was sent on a mission to Manitoba, Canada, where he spent the rest of his life.
After Rigdon"s death in July 1876, Post succeeded him as leader of the church, but died three years later after an extended illness.
