Seventh-day Adventist Church

Adventist · 1861–1863 · United States; worldwide

The Sabbatarian Adventists — holding that October 22, 1844 marked Christ's entry into the heavenly sanctuary rather than His return, and keeping the seventh-day Sabbath — organized as the Seventh-day Adventist Church by 1863; now a large worldwide denomination with extensive medical and educational institutions.

Seventh-day Adventist Church was formed between 1861 and 1863, as a process rather than a single event. Seventh-day Adventist Church continues today. Seventh-day Adventist Church's institutional line runs back through Millerite movement, Triennial Convention, Particular Baptists, Congregationalists, Church of England, Roman Catholicism to the post-apostolic church. No body on this tree is the assembly of Acts 2; where a body claims that, the claim appears in the claimed-lineage layer.

Between the post-apostolic church and Seventh-day Adventist Church stand 5 divisions along the institutional line, counting separations and disputed forks, not mergers, renewals or national organizations.

Solid lines are separations and unions; dashed lines are renewals that began inside a body; dotted gray lines are national organizations of one communion; a diamond marks a fork event where neither side is drawn as the one that left. Every line runs back to the post-apostolic church; no body descends from the assembly of Acts 2. Dashed gray boxes mark the institutional line after the apostles, shown as departure; no line of descent is drawn from Pentecost. A verdict appears on a box once its section is published.

Claimed lineage

What this tradition says about its own origin · restoration

Official FB13 text: 'The universal church is composed of all who truly believe in Christ, but in the last days, a time of widespread apostasy, a remnant has been called out to keep the commandments of God and the faith of Jesus… symbolized by the three angels of Revelation 14.' (Rev 12:17; 14:6–12; 18:1–4). FB18 names the gift of prophecy (E. G. White) 'an identifying mark of the remnant church.'

The documented record: Documented origins in the Millerite movement of 1831 to 1844 and the Sabbatarian branch organized in 1861 to 1863.

In the explorer's claimed view this renders as a dashed line, labeled "pattern claimed, not descent".
