Unitas Fratrum

Pre-Reformation dissent · 1457 · Bohemia and Moravia; Saxony; worldwide missions

Heirs of Jan Hus, organized at Kunvald in 1457 — sixty years before Luther — around scripture's supremacy and Sermon-on-the-Mount discipleship; driven underground after 1620 and renewed at Herrnhut in 1722, whence the name Moravian Church.

Unitas Fratrum was formed in 1457. Unitas Fratrum continues today. Unitas Fratrum's institutional line runs back through 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 Unitas Fratrum 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.
