Mr. Sellars, a longtime collaborator of Mr. Adams, compiled the libretto from existing poems and texts ranging from the Bible to the writings of the Roman Catholic activist DorothyDay.
Sellars tells the story through texts ranging from those by the 12th-century mystic Hildegard von Bingen to the 20th-century radical Catholic activist DorothyDay, from poetry by Louise Erdrich and Rosario Castellanos to excerpts from the Old and News Testaments.
