VI. Concerning the Office of the Lord’s Day
In the Lists appended to these General Rubrics the days of the year are treated under the heading of Sundays, Ferias, Vigils, and Feasts, but these terms are somewhat overlapping. Most Vigils are ferial in character, but a few are festive. Ferias take their Office from their Season, and therefore some are festive in character. All Sundays are Feasts, but their Office so largely determines that of the following week that they must be treated in a class apart from other Feasts. Saturday is the Eve of Sunday, and in liturgical usage is still known as the Sabbath, and therefore Vespers of Saturday is Sabbath Vespers and is not necessarily termed I Vespers of Sunday, even though it is such in fact whenever the Office of the Lord’s Day is said on Sunday.
Attention is therefore called to the following rules for the Office of the Lord’s Day:
1. The Office o Sundays is of semidouble rite, except for the following, when it is of double rite viz., Easter, Low, Pentecost and Trinity Sundays. However, since the Sunday Office is in honour of our Lord, it is accorded certain privileges which do not pertain to other Semidoubles, and by which it has in precedence a rank similar to greater Doubles; that is to say: (a) Sundays have certain rights of transference, and even of anticipation, and (b) their Office is preferred to all Semidoubles, and to all Doubles which are not I or II Class, in which cse the said Semidouble or Double cedes its Office is commemorated in the Sunday Office, and so is said to be simplified, for it is treated as a Simple. (But see Rubric III.)
2. It is to be understood, therefore, that when a simplified Semidouble or Double is commemorated in the Sunday Office the Office, the Office of the Lord’s Day acquires the rights which belong to that of his Saints’ Offices, in respect to these things: – (a) When on Sunday there is made a Commemoration of Double, or of a day within an Octave, or of an Octave Day (even Simple), then the Common Commemoration, the Preces, and the Athanasian Creed are omitted. (b) And in the foregoing cases, and also in the case of a semidouble Feast which is not a day within an Octave, Lesson ix is read of the Sunday, and not of the commemoration, for the said Feasts are in this respect treated as Simples.
3. The Sundays in privileged Octaves take their Office from the Feast, rather than from the seasonal Office for ordinary Sundays.
4. The overplus of Sunday Offices Epiphanytide and Trinitytide may be reassigned (as is stated in their Propers) according to the scheme exhibited in the third Table at the end of these General Rubrics.
