A Diverse Movement
The Washington, New Hampshire, roots also illustrate the diversity within the heritage of Seventh-day Adventists. It was Rachel Oakes, a Seventh-day Baptist, that convinced some of the members of the Washington church about the continuing validity of the seventh-day Sabbath. Not all mid-nineteenth century churches would give a fair hearing to the insights of a woman. Besides that, Thomas Preble, who attended that church and wrote an influential tract on the seventh-day Sabbath, was a Freewill Baptist. Frederick Wheeler, who served as their pastor, was a Methodist minister. We thus have substantial diversity within that original church. At least five different religious faiths formed the first Sabbath keeping Christian Adventist church. Within that diversity, however, unity over central issues prevailed.
Shortly after settling on a denominational name in 1860, Seventh-day Adventists began to talk about a worldwide movement. After all, didn't Christ urge to "go ye into all the world, and preach the gospel to every creature" and didn't Revelation talk of "the everlasting gospel" to be proclaimed to "them that dwell on the earth, and to every nation, and kindred, and tongue, and people"?
In 1861 it was discovered that at least five in Ireland were practicing Seventh-day Adventists. But how could a group of only a few thousand perform the task of worldwide evangelism? The denomination was officially organized on May 21, 1863, when the movement included some 125 churches and 3,500 members. By 1864 Michael Belina Czechowski, a former Catholic priest, decided to spread the Seventh-day Adventist message throughout Europe. In 1874 the church was ready to send abroad its first official missionary, J. N. Andrews, who left the United States for Switzerland. By the end of the century Seventh-day Adventism had become worldwide in scope.
