Rigdon believed that he could find in the New Testament the ordinances of Christ's Church, which could be established in the nineteenth century through the direction of God's Holy Spirit in the lives of righteous men. He claimed that God revealed to him that he would become a latter-day John the Baptist, a voice crying in the wilderness, to proclaim the establishment of the Kingdom of God and the second coming of Christ.
In 1830 he and his congregation embraced the Mormon movement, and Rigdon became one of the most important converts that Mormonism has ever gained. His acceptance of Mormonism gave the sect the prestige which allowed its missionaries to obtain audiences throughout the Western Reserve. Soon the Church, through Rigdon's influence, moved its headquarters to Kirtland, Ohio, where rapid growth ensued.
