The structure of Lauds in the post-1911 Office is the same as that of Vespers: introductory rites, five antiphons and psalms (or to be precise, four psalms and an OT canticle), chapter, hymn, versicle and response, antiphon on the Benedictus, collect, commemorations and Suffrage.
Last year examples of Lauds were given here and here. Today's ferial Office will be examined as another example. It should be noted that in Choir Mattins and Lauds are always celebrated as one service with the exception of Christmas when Mattins precedes the first Mass and Lauds follow it. However, the previous examples and today's ferial Office will treat Lauds as a separate service for the purpose of explanation.
The Office is found in the section of the Breviary 'Feria Sexta ad Laudes I'. Lauds begins with (Pater & Ave) the introductory Deus in adjutorium, the response Domine, ad adjuvandum, the Lesser Doxology and Alleluia. The antiphon fragment (only) Exalate is said and then Psalm 98, Dominus regnavit, the Lesser Doxology and then the entire antiphon Exaltate Dominum...in monte sancto ejus is recited. The same pattern, antiphon fragment, psalm, Lesser Doxology and repitition of the entire antiphon is repeated for the remaining three psalms and OT Canticle.
After the repitition of the last antiphon the chapter Nox praecessit, hymn Aeterna caeli gloria and then the versicle Repleti sumus mane and the response Exsultavimus. The fragment (only) of the antiphon on the Benedictus, Per viscera misericordiae is said followed by the Benedictus, Lesser Doxology and the entire antiphon.
The collect from last Sunday is then said Excita, quaesumus. After that the Suffrage of the Saints is said. This is printed in the section of the Breviary 'Ordinarium divini Officii ad Laudes'. It consists of the antiphon Beata Die Genitrix, versicle Mirificavit, response Et exaudivit and the collect A cunctis nos.
Benedicamus Domino and Deo gratias follow. Then Fidelium animae.., Dominus det nobis suam pacem and its response and then Salve Regina, its versicle and collect etc.
Tomorrow we will revisit the Little Hours of Terce, Sext and None which due to the anticipated Vigil of St. Andrew have the ferial preces.
