Although formed as a "business convenience" with the purpose of publishing and distributing Bible-based literature and managing the funds necessary for that task, the corporation from the 1920s began its transformation into the "religious society" Russell had insisted it was not, introducing centralized control and regulation of Bible Student congregations worldwide. In 1938, Rutherford introduced the term "theocracy" to describe the hierarchical leadership of Jehovah's Witnesses, with "Consolation" explaining: "The Theocracy is at present administered by the Watch Tower Bible and Tract Society, of which Judge Rutherford is the president and general manager." The society appointed "zone servants" to supervise congregations and in a "Watchtower" article Rutherford declared the need for congregations to "get in line" with the changed structure.
