Mormonism, Oliver Cowdery was born in October 3rd, 1806, in Wells Vermont. Before he met Joseph Smith, Martin Harris was ascribing for Joseph. He lost the 116 pages that he and Joseph translated, and the Lord took the Plates from Joseph for a while. After he got them back, Oliver Cowdery, hearing about the Gold Plates and having a vision about them, traveled to where Joseph was and scribes for Joseph. While working on the translation, Joseph and Oliver came across a scripture talking about the priesthood. They prayed about it and went by the Susquehanna River, where John the Baptist came and blessed Joseph and Oliver with the Aaronic Priesthood. After receiving the priesthood, they went into the river and baptized each other. The went into the forest, and prayed some more, then the Apostles Peter, James, and John came and blessed them with the Melchizedek Priesthood. Days later, Oliver Cowdery, David Whitmer, and Martin Harris were able to have the privilege of being shown the Gold Plates by Joseph. They later wrote what would be known as the Testimony of the Three Witnesses. Oliver and Joseph were able to finish translation and through the help of Martin Harris, they were able to print the Book of Mormon.
After the restoration of the Church in 1830, Oliver had some disagreements with Joseph. In 1838, he was excommunicated from the Church, mainly with competing with being the leader of the Church, not following some of the revelation Joseph inquired from the Lord, and not appearing on a hearing about his membership in the Church.
Oliver joined a Methodist church for some years, being secretary, doing some editorials for local newspapers, and practicing law.
In 1848, he met Brigham Young in Winter Quarters, Nebraska, and asked him to be re-baptized into the church. This was taken to a council and was unanimously approved. Oliver was re-baptized into the church on November 12, 1848.
On March 3rd, 1850, Oliver died due to health problems, causing him to not be able to relocate to Utah Territory. He died in David Whitmer's Home in Missouri.
