It is customaty in our monastery to celebrate Vigils the evening previous in anticipation of the next day. Each hour begins with an introduction. It the prayer is held as a group, use a verse style in which a person leads and the rest join in response. The first office of the day has a different introduction. All other offices of the day have the same introduction.
Glory be. . .
After the introduction at Lauds the invitatory is prayed. Following the hymn, we enter into the heart of the liturgical hours, the Psalter. The psalms proper are those used for Ordinary Time, unless otherwise specified for the season or feast day. Simply follow what is written. This is done to keep in mind the season and the mysteries of Christ's life that are to he celebrated at various time of the seasonal sections and the sanctoral section.
