These three Anaphorae, or "quddashas", are among the oldest in Christendom. That of Nestorius is reserved for five days in a liturgical year: Denha (Epiphany), the first Friday after Denha (John the Baptist), the fourth Friday of the Denha (the Greek Fathers), the Thursday of Pes’ha (Maundy Thursday) and the Wednesday of the Ascension of Our Lord. That of Theodore is used from the first Sunday of the Weeks of Annunciation to Oshana Sunday (Palm Sunday). On all the other days that of Addai and Mari is used.
