Church of God (Seventh Day)

Adventist · 1866 · United States

Sabbatarian Adventists who did not join the 1863 SDA organization, organized separately in 1866; the line from which, much later, Armstrongism derived (a later-pass item).

Church of God (Seventh Day) was formed in 1866. Church of God (Seventh Day) continues today. Church of God (Seventh Day)'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 Church of God (Seventh Day) 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.
