United Church of Christ in Japan

United and uniting churches · 1941 · Japan

The coerced union: Japan's wartime state compelled Protestant merger in 1940–41 to control the churches; when the law fell in 1945, the Episcopal, Lutheran, part of the Baptist and Holiness bodies, and the Salvation Army withdrew — the tree's standing witness that union by decree is not oneness. Remains Japan's largest Protestant body.

United Church of Christ in Japan was formed in 1941. United Church of Christ in Japan continues today. United Church of Christ in Japan's institutional line runs back through 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 United Church of Christ in Japan 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.
