"Mäṣḥafä Kedus" (Holy Scriptures) is the name for their religious literature. The language of the writings is Ge'ez, which also is the liturgical language of the Ethiopian Orthodox Church. The holiest book is the Orit (meaning "law"), which consists of the Octateuch: Five Books of Moses with Joshua, Judges and Ruth. The rest of the Bible has secondary importance. They are Book of Lamentations from the canon and part of the Book of Jeremiah, as it does in the Orthodox Tewahedo biblical canon.
