Adventism is the family born in expectation of Christ's soon return, centered on the Seventh-day Adventist Church, which keeps the seventh-day Sabbath, proclaims the three angels' messages, and awaits the investigative judgment's close and the Advent.
Adventism arose from the Millerite movement in America, which expected Christ's return in 1844 and survived the Great Disappointment by re-reading the prophecy: in that year, Adventists teach, Christ entered the final phase of his heavenly sanctuary ministry, the investigative judgment. Under Ellen G. White's prophetic guidance the Seventh-day Adventist Church organized in 1863 and grew into a world church marked by Sabbath observance, health reform, education, and medical mission.
Ultimate Reality
God is the Trinity of Scripture, and history is the theater of a great controversy between Christ and Satan over God's law and character. The controversy explains evil without making God its author: Satan's charges against God's government must be answered openly, and the judgment vindicates God before the universe as much as it settles human destinies.
The Human Condition
Human beings are mortal wholes, not immortal souls in bodies: death is a sleep until the resurrection, and the dead know nothing. This wholistic anthropology grounds Adventist health teaching — the body is the temple of the Spirit, and diet, rest, and temperance are spiritual disciplines, practiced since the church's health reform vision of 1863.
Knowledge and Truth
Scripture is the supreme authority; prophecy is read by the historicist method, with Daniel and Revelation as the church's map of history's end. Ellen White's writings are held as a prophetic ministry, 'a lesser light to lead to the greater light' of the Bible — authoritative for Adventist life, tested by Scripture, and a standing question in conversation with other Christians.
Right and Wrong
The Ten Commandments stand unabridged, and the seventh-day Sabbath — Friday sunset to Saturday sunset — is their sign: creation's memorial and the loyalty test of the last days in Adventist reading of Revelation. The remnant church proclaims the three angels' messages of Revelation 14, calling worshippers out of Babylon's confusion; tithing, dress and diet standards, and noncombatancy in war have marked Adventist practice.
Human Destiny
The investigative judgment, running from 1844, ends before Christ returns; then the Advent, the resurrection of the righteous, a millennium in heaven during which the saints review the judgment of the wicked, and finally the execution of judgment, the cleansing of the earth by fire, and the new earth where sin and death are no more — annihilation, not eternal torment, being the fate of the finally impenitent.
The Conversation
Adventism asks Sunday-keeping Christians where Scripture changed the Sabbath, and it asks the wider church whether death as sleep and hell as extinction answer the problem of eternal torment more biblically. It presses itself on 1844 and the sanctuary doctrine's biblical warrant — the question its own scholars debated at Glacier View in 1980 — and it offers its hospitals, schools, and longevity research as evidence for the wholeness it preaches.
