It is the custom at Silverstream Priory, as it is in many Benedictine monasteries, to gather in Chapter on the Ember Wednesday of Advent to hear the solemn proclamation of the Gospel of the Annunciation, the Missus Est, so called from the first words of the text: Missus est angelus Gabriel, “The Angel Gabriel was sent from God” (Luke 1:26). Following the Gospel, the abbot delivers a sermon Super Missus Est, that is, on the Gospel of the Annunciation.
