"The liturgical use of the Athanasian Creed was Frankish in origin (ninth century) and spread through the influence of the Cluniac reform (tenth century), but only found its way to Rome in the Supplementary prayers in the twelfth and thirteenth century" (Burton and Myers, _op. cit_., p. 51). _Rubrics_. Athanasian Creed, to be said (1) Trinity Sunday, (2) Sundays after Epiphany, (3) Sundays after Pentecost unless there be in (2) and (3) the commemoration of a double, or of an octave. Why is prayer offered at this first hour of the day? Writers on liturgy answer, 1st to offer to God the first fruits of our day, of our work, of our devotion, following in this the example of Christ, Who from His first entry into the world offered Himself to His Father for the salvation of mankind. 2d To beg of Him to keep us safe during the day, 3d To beg of Him to keep us free from sin, "ut in diurnis actibus nos servet a nocentibus." "May God in all our words and deeds Keep us from harm this day. May He in love retain us still, From tones of strife and words of ill, And wrap around and close our eyes To earth's absorbing vanities. May wrath and thoughts that gender shame Ne'er in our breasts abide. And painful abstinences tame Of wanton flesh, the pride" (Hymn at Prime). _Rubrics_. The Office of Prime begins in choir with the silent recitation of _Pater Noster, Ave, Credo_. Then, if in choir (aloud) Deus in adjutorium. ... Domine ad adjirvandum. ... Gloria Patri.... Alleluia, or Laus tibi.... Then the hymn _fam lucis_ is said. The antiphon for the day is said as far as the asterisk (*), then the Psalms of the day's Office as arranged in the new Pian Psaltery, according to the day of the week, except on some special feasts, when the Psalms at Prime are the Sunday psalms. When the _ordo recitandi_ marks an Office as _officium solemne_ (an excepted feast), the psalms at Lauds and Hours are the Sunday psalms; and at Prime the psalm _Deus in nomine tuo_ (Psalm 53) takes the place of Psalm _Confitemini_ (Psalm 117). At Prime, and at the small Hours, Terce, Sext, None, only one antiphon is said. It is said in full at the end of the last Psalm in each Hour. The Capitulum, the little Responsory, _Christe_, _Fili Dei vivi_ ... is then said. In this responsory the versicle _Qui sedes ad dexteram Patris_ is sometimes changed, e.g., in paschal time it is, _Qui surrexisti a mortuis_. The manner of reciting this responsory is sometimes not correctly understood, owing, perhaps, to its printed form in some Breviaries. The normal method is to repeat the _whole_ response, then say the versicle, and then the second portion of the response; then the _Gloria Patri el Filio et Spiritui Sancto, without the Sicut erat_, is said, and the response repeated. The versicle _Exsurge_ and the response _Et libera_ are then said. This is the method of recitation in all the small Hours and at Compline.
