How their histories relate
Ecclesial union · Various, 16th–20th centuriesA gradual processWider family
Part of one church enters communion with another while keeping its own liturgy, hierarchy and law.
The 23 Eastern Catholic churches did not form through one event. Several came from unions of parts of Eastern churches with Rome (the Union of Brest, 1596; Uzhhorod, 1646; the Melkite patriarchate, 1724; the Syro-Malankara Church, 1930); the Maronites and Italo-Albanians describe themselves as never having broken communion.Read in Eastern Catholic Churches historySource
