United Church of Christ

United and uniting churches · 1957 · United States

The 1957 union of the Congregational Christian and Evangelical & Reformed churches — the first American union across differing polities and historical backgrounds, framed by its founders as a step toward healing the Reformation's divisions.

United Church of Christ was formed in 1957. United Church of Christ continues today. United Church of Christ's institutional line runs back through 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 United Church of Christ stand 3 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.
