that having used the Treasury in a variety of ways over the last couple years, I have definitely decided that I am truly most at home using it the way I did at first. Here's how:
Matins/Lauds: Opening Versicles, Monthly Psalter (see chart on pages 1436-1437 - easiest is to write the divisions into the Psalter itself), Hymn stanza, OT reading, Responsory, Canticle (Te Deum on Sundays; Benedictus all other days), Kyrie, Our Father, Prayer of the Day, Prayer for the Day of the Week (pp. 1306-1309), Collect for Grace, Benedicamus, Benediction
Vespers: Opening Versicles, Monthly Psalter (as above), Hymn stanza, NT reading, Responsory, Writing, Versicle and Magnificat, Kyrie, Our Father, Prayer of the Day, Intercessions for family and for those who have asked my prayers, Collect for Peace, Benedicamus, Benediction
The heart of this way of using the Treasury is the Monthly Psalter. Truly, the more I use the Psalms, the more I have come to love them and find them to be the very best prayers we as the Church can ever offer. As Bonhoeffer said, they're all expansions of the petitions of the Our Father.
