the rest of the Ten Commandments had not been revised, so also the injunction to "remember the Sabbath day to keep it holy" remained in full force. This theological point turned the young group into a powerful force for religious liberty. Growing into its full stature in the late 19th century and early 20th century, these Adventists opposed Sunday laws on every side. Many were arrested for working on Sunday. In fighting against the real threat of a legally established National Day of worship, these Sabbatarians had to fight for their liberty on a daily basis. Soon, they were fighting for religious liberty on a broader, less parochial basis. Worldwide mission Adventist effort for a world-wide proclamation of their message began with the mailing of publications. In 1874 J. N. Andrews became the first official Adventist missionary to travel overseas. Working in Switzerland, he sought to organize the Sabbath-keeping companies under one umbrella. During the 1890s Adventists began to enthusiastically promote a world-wide mission effort. A world vision and growing pains, 1880–1915 1888 General Conference In 1888, a General Conference Session occurred in Minneapolis. This session involved a discussion between the then General Conference president, G. I. Butler; editor of the review, Uriah Smith; and a group led by E. J. Waggoner and A. T. Jones about the meaning of "Righteousness by Faith" and the meaning of the law in Romans and Galatians. Ellen G. White also addressed the conference. Organizational Developments From the early 1860s the church had three levels of government: the local church, the conference, and the General Conference. As ideas developed, organizations came into existence to move forward the ideas; i.e. Sabbath Schools, health reform and medical work, printing, distribution of literature, religious liberty, missions, etc. All moved forward under the societies formed to do so. As the work progressed, the managing of all these societies became quite cumbersome. As conferences developed in far off lands, it became obvious that the General Conference could not oversee the day-to-day needs of the conferences. This led to the development of Union conferences in Australia and Europe in the late 1890s and to the development of districts in the United States. The 1901 and 1903 General Conference sessions reorganized the church's structure to include union conferences which managed a group of local conferences in their domain. By the end of 1904, the various societal interests became incorporated as departments
