[3] This mission brought in several influential converts and introduced the church to Kirtland, Ohio and Jackson County, Missouri, which would become religiously significant to Mormonism.
[5] Peterson was called as a missionary to the Native Americans (referred to as Lamanites by early members of the Church) in Indian Territory with Parley P. Pratt, Oliver Cowdery and Peter Whitmer,[6] and left Fayette, New York on October 17, 1830.
On this journey, they went through Kirtland, Ohio where they met a Reformed Baptist pastor friend of Pratt's, Sidney Rigdon.
Peterson and the other missionaries continued to Jackson County, Missouri, on the borders of Indian Territory, where they established a tailor shop and baptized about 40 or 50 settlers.
Peterson's missionary call and reprimand are both recorded in the Doctrine and Covenants, a book of Latter Day Saint scripture, in sections 32 and 58.
