established in Battle Creek, Michigan, on May 21, 1863, with a membership of 3,500. The denominational headquarters were later moved from Battle Creek to Takoma Park, Maryland, where they remained until 1989. The General Conference headquarters then moved to its current location in Silver Spring, Maryland. The denomination in the 1870s turned to evangelism through missionary work and revivals, tripling its membership to 16,000 by 1880 and establishing a presence beyond North America during the late 19th century. Rapid growth continued, with 75,000 members in 1901. By this time the denomination operated two colleges, a medical school, a dozen academies, 27 hospitals, and 13 publishing houses. By 1945, the church reported 210,000 members in the US and Canada, and 360,000 elsewhere; the budget was $29 million and enrollment in church schools was 140,000. The church's beliefs and doctrines were first published in 1872 in Battle Creek, Michigan as a brief statement called "A Synopsis of our Faith".

According to Adventist scholars, the teachings and writings of White, ultimately proved influential in shifting the church from largely semi-Arian roots towards Trinitarianism. Adventists, for the most part, credit her with bringing the Seventh-day Adventist church into a more comprehensive awareness of the Godhead during the 1890s. The Adventist Church adopted Trinitarian theology early in the 20th century and began to dialogue with other Protestant groups toward the middle of the century, eventually gaining wide recognition as a Protestant church. Christianity Today recognized the Seventh-day Adventist church as " the fifth-largest Christian communion worldwide" in its January 22, 2015 issue. Although her husband claimed that her visions did not support the Trinitarian creed, her writings reveal a growing awareness on the "mystery of the GodHead". Adventists, for the most part, credit her with bringing the Seventh-day Adventist church into a more comprehensive awareness of the Godhead during the 1890s. Through continued Bible study, and decades-long debate, the denomination eventually concluded that Scripture does explicitly teach the existence of a triune God, and it affirmed that biblical view in the non-credal
