Presbyterian Church (U.S.A.)

Reformed and Presbyterian · 1983 · United States

The 1983 Atlanta reunion of the northern and southern churches closed American Presbyterianism's longest-running schism; the mainline body since, with conservative departures (EPC 1981 pre-merger, ECO 2012 post) tracked in the fact bank.

Presbyterian Church (U.S.A.) was formed in 1983. Presbyterian Church (U.S.A.) continues today. Presbyterian Church (U.S.A.)'s institutional line runs back through Presbyterian Church in the U.S.A. (1789 line), Church of Scotland, Reformed, 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 Presbyterian Church (U.S.A.) stand 2 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.
