sermons, which by his death totaled 50,000 printed pages, with almost 20 million copies of his books printed and distributed around the world. In 1886, he wrote The Divine Plan of the Ages, a 424-page book that was the first of what became a six-volume series called "Millennial Dawn," later renamed "Studies in the Scriptures," which established his fundamental doctrines. As a consequence, the Bible Students were sometimes called "Millennial Dawnists". Congregations The first study groups or congregations were established in 1879. Within a year more than 30 of them were meeting for six-hour study sessions under Russell's direction, to examine the Bible and his writings. The groups were autonomous ecclesia, an organizational structure Russell regarded as a return to "primitive simplicity". In an 1882 Watch Tower article he said his nationwide community of study groups was "strictly unsectarian and consequently recognize no sectarian name ... we have no creed (fence) to bind us together or to keep others out of our company. The Bible is our only standard, and its teachings our only creed." He added: "We are in fellowship with all Christians in whom we can recognize the Spirit of Christ." In 1884 he said the only appropriate names for his group would be "Church of Christ", "Church of God" or "Christians". He concluded: "By whatsoever names men may call us, it matters not to us; we acknowledge none other name than 'the only name given under heaven and among men' — Jesus Christ. We call ourselves simply Christians." In 1895, discussing the best form of meeting to study his writings, Russell warned: "Beware of organization. It is wholly unnecessary. The Bible rules will be the only rules you will need. Do not seek to bind others' consciences, and do not permit others to bind yours." Elders and deacons were elected by congregations and Russell tolerated a great latitude of belief among members. He discouraged formal disciplinary procedures by congregation elders, claiming this was beyond their authority, instead recommending that an individual who continued in a wrong course be judged by the entire ecclesia, or congregation, which could ultimately "withdraw from him its fellowship". Disfellowshipping did not mean the wrongdoer was shunned in all social circumstances or by all Bible Students. In 1894, Russell introduced the role of "pilgrim" workers, men chosen for their maturity, meekness and Bible knowledge, who would visit congregations for up to three days
