After receiving his education in Vermont and New York, Oliver became a schoolteacher. While teaching school in Manchester, New York, in 1829, he learned of Joseph Smith and his angelic visitations. When the school term ended in April 1829, Oliver and Samuel Smith, the brother of Joseph Smith, journeyed to Harmony, Pennsylvania, for the purpose of seeing Joseph and learning more about his heavenly visitations and the gold plates. “Near the time of the setting of the Sun, Sabbath evening, April 5^th, 1829, my natural eyes, for the first time beheld this brother,” wrote Oliver. “On Tuesday the 7^th, [I] commenced to write the book of Mormon.”[1]

From April 1829 to April 1838 Oliver Cowdery was a close associate and friend of the Prophet Joseph. He scribed most of the Book of Mormon as Joseph translated the sacred writ. On May 15, 1829, he and Joseph received the Aaronic Priesthood on the banks of the Susquehanna River from John the Baptist and the Melchizedek Priesthood from ancient apostles Peter, James, and John a few weeks later. Several of the early revelations in the Doctrine and Covenants were instructions to Oliver, who was named the second elder of the Church at the organizational meeting in Fayette, New York.

Oliver’s sacrifice to share the message of the Restoration from New York to the western frontier of the United States bespeaks his commitment to the Lord. Of Oliver’s ability to stir the hearts of men to greater good Wilford Woodruff wrote, “I have seen Oliver Cowdery when it seemed as though the earth trembled under his feet. I never heard a man bear a stronger testimony than he did when under the influence of the Spirit.”[2] No wonder on December 5, 1834, Oliver was ordained an assistant to the Prophet Joseph. On that occasion Joseph said, “I lay my hands upon thee and ordain thee an assistant-president to the High and Holy Priesthood, in the Church of the Latter-day Saints.”[3] On April 3, 1836, Oliver was with Joseph as priesthood keys were received from ancient prophets Elijah, Elias, and Moses in the Kirtland Temple.

Although Oliver stands alone as the contemporary who received many glorious manifestations with the Prophet Joseph Smith, nine formal charges were drawn against him on April 7, 1838, before the Far West high council, including the charge that he urged vexatious lawsuits be brought against the Saints and the charge that he sought to destroy the character of the Prophet Joseph. Oliver refused to attend the high council meeting when the charges were discussed. “Give me my freedom or take my life!” he wrote. “I shall no longer be bound by the chains of hell. I shall speak out when I see a move to deceive the ignorant.”[4] After deliberating on the charges against Oliver, the Far West high council excommunicated him on April 12, 1838.

Although Oliver had lost fellowship with the Saints, Joseph Smith continued to reach out to him and encouraged the Quorum of the Twelve to do the same: “Write to Oliver Cowdery and ask him if he has not eaten husks long enough? If he is not almost ready to return, be clothed with robes of righteousness, and go up to Jerusalem?”[5] For years, Oliver rejected their entreaties.

During those years, he was a lawyer in Tiffin, Ohio, and in Elkhorn, Wisconsin. Of his legal work Oliver said, “My business is steadily increasing—nothing operates against me, except the fact that I have formerly been connected with what is now an important church.”[6] Yet he wrote on February14, 1847, to Phineas Young, “No day passes without our thoughts being turned toward our relatives and loved friends, who are toiling and struggling in the far off wilderness, during a cold and pitiless winter” and expressed interest in returning to Church fellowship.[7]

On November 11, 1847, Brigham Young wrote to Oliver:

Return to our father’s house, from whence thou hast wandered, and partake of the fatted calf and sup and be filled, and renew thy testimony to the truth of the Book of Mormon with a loud voice, and faithful heart and you will soon feel the Holy Ghost burning your bones like fire in the dry stubble . . .  and the Saints, His sons and daughters will with open arms hail thee as their long lost brother found in the New and Everlasting Covenant.[8]

Oliver journeyed from Elkhorn to Kanesville, Iowa, to be with the Saints. At a conference held on October 21, 1848, at Kanesville, he addressed the assembled by saying,

Friends and Brethren—My name is Cowdery—Oliver Cowdery. In the early history of this Church I stood identified with her, and one in her council. . . . I wrote, with my own pen, the entire Book of Mormon (save a few pages) as it fell from the lips of the Prophet Joseph Smith. . . . That book is true.

In early November 1848 Oliver requested that the Kanesville high council grant him fellowship in the Church: “Brethren, for a number of years, I have been separated from you. I now desire to come back. I seek no station. I only wish to be identified with you.”[9] Upon the motion of Orson Hyde, Oliver Cowdey was welcomed back into Church fellowship.

After his baptism, Oliver helped Orson Hyde publish the Frontier Guardian newspaper until April 1849. He then journeyed with his wife, Elizabeth Whitmer Cowdery, to Richmond, Missouri, to visit her family. From Richmond, Oliver wrote of his struggles with his “old difficulty of the lungs.” Just before his death on March 3, 1850, at the David Whitmer home in Richmond, Oliver admonished his loved ones “to live according to the teachings set forth in the Book of Mormon and he promised them that if they were faithful to this they would be assembled with him in Heaven.”[10]
