Prime, or the First Hour, is one of the canonical hours of the Divine Office, said at the first hour of daylight (6:00 a.m. at the equinoxes but earlier in summer, later in winter), between the dawn hour of Lauds and the 9 a.m. hour of Terce. It remains part of the Liturgy of Eastern Christianity, but suppressed within the Roman rite by the Second Vatican Council,Sacrosanctum Concilium, Article 89(d) although a number of monastic communities and clerical institutes continue to use it as they do the rest of the preconciliar Roman rite. In the Coptic Church, a denomination of Oriental Orthodox Christianity, the office of Prime is prayed at 6 am in eastward direction of prayer by all members in this denomination, both clergy and laity, being one of the seven fixed prayer times. Roman Catholic clergy under obligation to celebrate the Liturgy of the Hours may still fulfil their obligation by using the edition of the Roman Breviary promulgated by Pope John XXIII in 1962,Summorum Pontificum , article 9 §3 which contains Prime. Like all the liturgical hours, except the Office of Readings, it consists mainly of Psalms. It is one of the Little Hours.

Name From the time of the early Church, the practice of seven fixed prayer times have been taught; in Apostolic Tradition, Hippolytus instructed Christians to pray seven times a day "on rising, at the lighting of the evening lamp, at bedtime, at midnight" and "the third, sixth and ninth hours of the day, being hours associated with Christ's Passion." With respect to praying in the early morning, Hippolytus wrote: "Likewise, at the hour of the cock-crow, rise and pray. Because at this hour, with the cock-crow, the children of Israel refused Christ, who we know through faith, hoping daily in the hope of eternal light in the resurrection of the dead."

The word "Prime" comes from Latin and refers to the first hour of daylight (that which begins at sunrise). John Cassian (c. 360 – c. 435) describes it as matutina (hora),De Coenobiorum Institutis (Institutes) in Patrologia Latina (Migne) vol. 49, col. 126A ("a" or "the") "morning hour" (translated also as "Mattins"),John Cassian, The Twelve Books on the Institutes of the Coenobia and the Remedies for the Eight Principal Faults book 3, chapter 4 a description applied also, according to Alardus Gazaeus even by Cassian,Patrologia Latina (Migne) vol. 49, coll. 127C−128B] to the dawn hour of Lauds. Benedict of Nursia (c. 480 − c. 547) refers to Prime by using the term "primae tempore" ("the time of First Hour") for Prime and uses matutino tempore ("morning time") to speak of Lauds, reckoning Lauds as the first of the seven daytime offices, which he associates with Psalm 118/119:164, "Seven times a day I praise you for your righteous rules",Psalm 119:164 and which he distinguishes from the one nocturnal office of Night Watch, which he links with Psalm 118/119:62, "At midnight I rise to praise you, because of your righteous rules",Psalm 119:62Regula S.P.N. Benedicti, caput 6Rule of Saint Benedict, chapter 16

In the Antiphonary of Bangor (perhaps c. 700) what is generally called prima (hora) is called secunda.F.E. Warren (editor), The Antiphonary of Bangor (Harrison and Sons, London 1895), part II, pp. 19, 20, 29, 32 F.E. Warren states: "'Secunda' as the equivalent of 'Prima', the usual title of the first of the Day-Hours is a very ancient title, but has now gone out of use. It is found in the Missale Gallicanum (p. 179), also in C.C.C.C. MS.272, a ninth century Rheims Psalter".Warren (1895), p. 58

In the Eastern liturgies, the names for this office in the various languages mean "first (hour)".

Origin John Cassian states that this canonical hour originated in his own time and in his own monastery in Bethlehem, where he lived as a novice: "hanc matitutinam canonicam functionem nostro tempore in nostro quoque monasterio primitus institutam." ("was appointed as a canonical office in our own day, and also in our own monastery, where our Lord Jesus Christ was born of a Virgin and deigned to submit to growth in infancy as man, and where by His Grace He supported our own infancy, still tender in religion, and, as it were, fed with milk"). Jules Pargoire concluded that the institution of Prime must be placed towards 382.Jules Pargoire, "Prime et Complines" in La Revue d'histoire et de Littérature, III (1898), 282–88; Dict. d'Archéologie et de Liturgie, I, 198; II, 1245, 1302, 1306. Fernand Cabrol identified the monastery in question as "not St. Jerome's monastery at Bethlehem, but another, perhaps one established beyond the Tower of Ader (or of the Flock) beyond the village of the Shepherds, and consequently beyond the modern Beth-saour; it has been identified either with Deïr-er-Raouat (convent of the shepherds) or with Seiar-er-Ganhem (enclosure of the sheep)".Fernand Cabrol, "Prime" in The Catholic Encyclopedia (New York 1911)

Cassian says this office was instituted because a period of rest was allowed after the nocturnal office and the office said shortly after it, but some monks abused this time of rest by staying in their cells and their beds right up to the time for Terce, and it was therefore decided to have a sunrise office that, moreover, brought the daylight offices to seven in line with Psalm 118/119:164, quoted above in connection with the Rule of Saint Benedict.

Western Church Fernand Cabrol says that Prime originally used only to contain a repetition of the Lauds Psalms 1, 57 (58), and 89 (90), but the monasteries that gradually adopted the new office changed its constitution as they liked. In spite of the many variations, one characteristic feature is the recitation of the Athanasian Creed. Saint Benedict assigns to Prime on Sundays four groups of eight verses of Ps. 118 (119), and on week-days three psalms, beginning with the first and continuing to Ps. 19 (20), taking three psalms each day (Pss. 9 (10) and 17 (18) being divided into two). This makes Prime like the other Little Hours of the day, which it resembles these in accompanying the psalms with a hymn, an antiphon, capitulum, versicle, and prayer. The Roman Breviary as decreed by Pope Pius V in 1568 in line with the decrees of the Council of Trent, assigns to Prime on Sunday of Pss. 53 (54), 117 (118) and the first four groups of eight verses of Ps. 118 (119); on each of the weekdays it assigns the same psalms as on Sunday except that it replaces Psalm 117 (118) with one of the Psalms from 21 (22) through 25 (26), which had previously all been at Sunday Prime. Each day therefore had in Prime two full psalms and the same two portions of Psalm 118 (119). The late 1911 reform of the Roman Breviary by Pope Pius X changed the psalmody radically, dividing several psalms into shorter portions. To Prime it assigned each day three psalms or portions of psalms, each day different.Table comparing the 1568 and the 1911 psalters

To these elements, which make Prime similar to the other Little Hours, Prime adds some prayers that are called the office of the chapter: the reading of the martyrology, the prayer Sancta Maria et omnes sancti ("May holy Mary and all the Saints"), a prayer concerning work, Respice in servos tuos ... Dirigere et sanctificare ("Look upon thy servants ... Direct and sanctify"), and a blessing. The fact that the monastic communities originally after Prime betook themselves to manual work or study is reflected in the prayer for the work ... et opera manuum nostrarum dirige super nos et opus manuum nostrarum dirige ("... and direct thou the works of our hands over us; yea, the work of our hands do thou direct"), and the prayer Dirigere. Later the reading of the martyrology, the necrology, the rule, and a prayer for the dead were added.

The Church of England's Book of Common Prayer dropped Prime with its first 1549 edition. A proposed 1928 version that Parliament rejected would have restored Prime, with the instruction that it be used in addition to (not instead of) Matins, and with optional reciting of the Athanasian Creed.

Eastern Christianity

Byzantine Rite In the Eastern Orthodox and Greek Catholic Churches the office of the First Hour is normally read by a single Reader and has very little variation in it. Three fixed psalms are read at the First Hour: Psalms 5, 89, and 100 (LXX). The only variable portions for most of the year are the Troparia (either one or two) and Kontakion of the Day. Whereas the other Little Hours are normally followed by other services, the First Hour is normally read immediately after Matins and so it is concluded with a dismissal by the priest. In the Russian usage, the dismissal is followed by a hymn to the Theotokos (the Kontakion of the Annunciation, Tone 8): "To thee, the champion leader, we thy servants dedicate a feast of victory and of thanksgiving, as ones rescued out of sufferings, O Theotokos; but as thou art one with might which is invincible, from all dangers that can be do thou deliver us, that we may cry to thee: Rejoice, thou Bride Unwedded!"

Variations During Great Lent a number of changes in the office take place. On Tuesday, Wednesday and Thursday, after the three fixed psalms, the Reader says a kathisma from the Psalter. The Troparion of the Day is replaced by special Lenten hymns that are chanted with prostrations. Then the psalm verses that follow the Theotokion, which are normally read, are instead sung by the choir. The Kontakion is also replaced by special Lenten hymns which are sung. Near the end of the Hour, the Prayer of St. Ephraim is said, with prostrations.

On Monday, Wednesday, and Friday of the Fourth Week of Great Lent, the Veneration of the Cross takes place at the First Hour.

During the Fifth Week of Great Lent, there is a kathisma only on Tuesday and Wednesday, due to the reading of the Great Canon of Saint Andrew of Crete on Thursday morning. If, however, the Great Feast of the Annunciation falls on that particular Thursday, the reading of the Great Canon will be moved to Tuesday and, as a result, a kathisma will be read on Monday, Wednesday and Thursday.

During Holy Week, on Monday, Tuesday and Wednesday, the services are similar to those during Great Lent except there is no reading of Kathismata, and instead of the normal Lenten hymns which replace the Kontakion, the Kontakion of the day (i.e., that day of Holy Week) is chanted. On Great Thursday and Saturday, the Little Hours are more like normal, except that a Troparion of the Prophecy, prokeimena, and a reading from Jeremiah are chanted at the First Hour on Great Thursday. On Great Friday, the Royal Hours are chanted.

During the Lesser Lenten seasons (Nativity Fast, Apostles' Fast and Dormition Fast) the Little Hours undergo changes similar to those during Great Lent, except the hymns are usually read instead of chanted, and there are no kathismata on weekdays. In addition, on weekdays of the Lesser Fasts, the Inter-Hour (Greek: Mesorion) may be read immediately after the First Hour (at least on the first day of the Fast).The Inter-Hours may also be read during Great Lent if there is to be no reading from the Ladder of Divine Ascent at the Little Hours. The Inter-Hours follow the same general outline as the Little Hours, except they are shorter. When the Inter-Hour follows the First Hour, the dismissal is said at the end of the Inter-Hour rather than at the end of the First Hour.
