Orientalium Ecclesiarum is the Decree on the Catholic Churches of the Eastern Rite from the Second Vatican Council. One of the shorter such documents, it was passed by the assembled bishops by a vote of 2,110 to 39 and promulgated by Pope Paul VI on November 21, 1964. The name means "Eastern Churches" in Latin, and is taken from the first line of the decree, as is customary with Roman Catholic official documents.
