===Adventism===
{{Main|Adventism}}
Adventism is a [[Christian eschatology|Christian eschatological]] belief that looks for the imminent [[Second Coming]] of Jesus to inaugurate the [[Kingdom of God]]. This view involves the belief that Jesus will return to receive those who have died in Christ and those who are awaiting his return, and that they must be ready when he returns. Adventists are considered to be both restorationists and [[Conservatism|conservative]] [[Protestants]].<ref>George R.

The Millerites were the most well-known family of the Adventist movements. They emphasized apocalyptic teachings anticipating the end of the world, and did not look for the unity of [[Christendom]] but busied themselves in preparation for Christ's return. Millerites sought to restore a prophetic immediacy and uncompromising biblicism that they believed had once existed but had long been rejected by mainstream Protestant and Catholic churches. From the Millerites descended the Seventh-day Adventists and the Advent Christian Church.

====Seventh-day Adventists====

The Seventh-day Adventist Church grew out of the Adventist movement, in particular the Millerites. The Seventh-day Adventist Church is the largest of several [[Adventism|Adventist]] groups which arose from the [[Millerites|Millerite]] movement of the 1840s in upstate [[New York (state)|New York]], a phase of the [[Second Great Awakening]]. Important to the Seventh-day Adventist movement is a belief in [[Progressive revelation (Christian)|progressive revelation]],<ref>{{cite web|url=http://www.andrews.edu/~damsteeg/Prog%20rev.html|title=Seventh-day Adventist Doctrines and Progressive Revelation}}</ref> teaching that the Christian life and testimony is intended to be typified by the [[Spirit of Prophecy (Adventist)|Spirit of Prophecy]], as explained in the writings of [[Ellen G. White]].

Much of the theology of the Seventh-day Adventist Church corresponds to Protestant Christian teachings such as the Trinity and the [[Biblical infallibility|infallibility of Scripture]]. Distinctive teachings include the [[soul sleep|unconscious state of the dead]] and the doctrine of an [[investigative judgment]]. The church is also known for its emphasis on diet and health, its holistic understanding of the person, its promotion of religious liberty, and its conservative principles and lifestyle.

The [[Worldwide Church of God]] arose from the [[Seventh Day churches]]. The personal ministry of [[Herbert W. Armstrong]] became the [[Radio Church of God]], which became the Worldwide Church of God. It later splintered into many other churches and groups when the Worldwide Church of God disassociated itself with the Restoration movements and made major attempts to join the Protestant branch of Christianity. The largest of these groups, the [[Living Church of God]] and the [[United Church of God]], continue in the tradition of the Worldwide Church of God as it was under the leadership of Herbert W. Armstrong.

====Advent Christian Church====

The Advent Christian Church is unaffiliated with Seventh-day Adventism, but considers itself the second "of six Christian denominations that grew out of the ministry of William Miller".<ref>''Midnight and Morning: The Millerite Movement and the Founding of the Advent Christian Church'', 1831-1860 by Clyde E. Hewitt (Venture Books, 1984), as cited by "The Advent Christian Church: An Introduction", [http://www.areachurches.com/adventinfo.html AreaChurches.com]</ref> As a "first-day" body of Adventist Christians established by ''The Advent Christian General Conference'' in 1860, the church's beliefs include "conditional immortality" and a form of "[[soul sleep]]".

Advent Christians such as [[George Storrs]] and [[Jonas Wendell]] influenced the [[Bible Student movement]].
