Celtic Rite


The term "Celtic Rite" is appliedto the various liturgical rites used in Celtic Christianity in Britain, Ireland and Brittany and the monasteries founded by St. Columbanus and Saint Catald in France, Germany, Switzerland, and Italy during the early middle ages. The term does not imply homogeneity; the evidence, scanty and fragmentary as it is, is in favour of considerable diversity.

The Welsh church

Before the 8th century AD there were several Christian rites in Western Europe. Such diversity of practice was often considered unimportant so long as Rome's primacy was accepted. Gradually the diversity tended to lessen so that by the time of the final fusion in the Carolingian period the Roman Rite, its Ambrosian variant, and the Hispano-Gallican Mozarabic Rite were practically all that were left.
British bishops attended the Council of Arles in A.D. 314 and the Council of Rimini in 359. Communication with Gaul may be inferred from dedications to St. Martin at Whithorn and at Canterbury, from the mission of Victridius of Rouen in A.D. 396 and those of Germanus of Auxerre, with St. Lupus in 429 and with St. Severus in 447, directed against the Pelagianism of which the bishops of Britain stood accused.
However much of Britain derived their religion from Irish missionsaries. Aidan of Lindisfarne, Foillan, Diuma, Finan of Lindisfarne, Jaruman and others evangalised the Anglo-Saxons. Ia of Cornwall and her companions, Saint Piran, St. Sennen, Petroc came to Cornwall and probably brought with them whatever rites they were accustomed to. Cornwall had an ecclesiastical quarrel with Wessex in the days of St. Aldhelm, which appears in Leofric's Missal, though the details of it are not specified.
The certain points of difference between the British Church and the Roman in prior to were: The rule of keeping Easter the tonsure the manner of baptizing. Gildas also records elements of a different rite of ordination.

Liturgy

There is a mass, probably of the 9th century, apparently Cornish since it mentions "Ecclesia Lanaledensis" and in honour of St. Germanus. It is quite Roman in type, probably written after that part of Cornwall had come under Saxon influence, but with a unique Proper Preface.The manuscript also contains glosses, held by Professor Loth to be Welsh but possibly Cornish or Breton. There is little other evidence as to what liturgy was in use.
Anglicans of the 19th century such as Sir William Palmer in his Origines Liturgicae and the Bishop of Chichester in his Story of the English Prayerbook proposed that Irenaeus, a disciple of St. Polycarp the disciple of St. John the Divine, brought the Ephesine Rite to Provence whence it spread through Gaul to Britain and became the foundation of the Sarum Rite. The Ephesine origin of the Gallican Rite rested first upon a statement of Colmán of Lindisfarne in 664 at the Synod of Whitby respecting the origin of Easter and second upon an 8th-century Irish writer who derived the divine office from Alexandria. Archbishop Nuttall also asserted the Eastern origin of the Irish rite. The Catholic Encyclopedia disagreed, asserting that the Sarum Rite is "merely a local variety of the Roman, and that the influence of the Gallican Rite upon it is no greater than upon any other Roman variety".
A letter from Pope Zachary to St. Boniface, and in cap. ix of the same book, after ordering the reordination of those ordained by Scottish and British bishops "who are not Catholic in their Easter and tonsure" and the asperging of churches consecrated by them. It has been conjectured that the British Church resembled the Hispanic in baptizing with a single immersion. This form had been allowed by Rome in the case of Iberia.

Easter

The Irish, the English, and the Britons adhered to the old cycle of 84 years instead of the newer cycle of 19 years and counted the third week of the moon from the 14th to the 20th instead of from the 15th to the 21st. Until 457, when the 532-year cycle of Victorius of Aquitaine was adopted at Rome, each agreed with Roman practice, differing from Alexandria and the East. In 525 Rome altered its rule again to the 19-year cycle of Dionysius Exiguus to conform to Eastern usage.
Colman at the Synod of Whitby may have had the Quartodeciman controversy in mind when he claimed an Ephesian origin for the Irish calculations of Easter. St. Wilfrid answered that according to the Quartodeciman rule Easter might be kept on any day of the week, whereas the Irish and those they had evangalised kept it on Sunday only. St. Aldhelm in his letter to King Gerontius of Dumnonia also seems to charge the Cornish with Quartodecimanism.
The Easter question was eventually settled at various times in different places. The following dates are derived from Haddan and Stubbs: Western, eastern and southern Ireland, 626-8; northern-west Ireland, 692; Northumbria, 664; East Devon and Somerset, 705; the Picts, 710; Iona, 716-8; Strathclyde, 721; North Wales, 768; South Wales, 777. Cornwall held out the longest of any, perhaps even, in parts, to the time of Bishop Aedwulf of Crediton.

Establishment of the Irish Rite

There were Christians in Ireland before Saint Patrick, but we have no information as to how they worshipped, and their existence is ignored by Tirechan's 7th-century Catalogus Sanctorum Hiberniae, which divides the saints of Ireland into three orders covering about 225 years from the coming of St. Patrick in 440 in the reign of Laoghaire MacNeil to the reign of Blathmac and Diarmait sons of Áed Sláine in 665. Each order is stated to have lasted for the reigns of four kings - symmetry is attained by omitting about six intervening reigns, but the outside dates of each period are clear enough, and the document relates customs of the Divine Office and the Easter and tonsure questions.
The first order was in the time of St. Patrick, from the reign of Laoghaire to that of Túathal Máelgarb. They were all bishops, 350 in number, founders of churches, all Romans, French, Britons and Scots. They had one Head, Christ, one leader, Patrick, one mass and one tonsure from ear to ear and they celebrated Easter a fortnight after the spring equinox.
The second order was of few bishops and many priests, 300 in number. It lasted from the end of the reign of Tuathal to that of Áed mac Ainmuirech. They had one head, Christ, they celebrated different Masses and different rules, they had one Easter, the fourteenth of the moon after the equinox, and one tonsure from ear to ear. They received a Mass from the Britons, David of Wales, Gilla, and Docus. The Life of Gildas tells how King Ainmuire mac Sétnai sent for Gildas to restore ecclesiastical order in his kingdom in which the Catholic faith was being laid aside.
The third order were priests and a few bishops, 100 in number, living in wildernesses on an ascetic diet, evidently hermits and monks. They had different masses, different rules, and different tonsures,, and celebrated different Easters, some on the fourteenth, some on the sixteenth, of the moon "with hard intention" which perhaps means "obstinately". These lasted from the reign of Áed Sláine to that of his two sons Diarmait and Blathmac.
The "unam celebrationem" of the first order and the "diversas regulas" of the second and third probably both refer to the Divine Office. The meaning seems to be that the first order celebrated a form of mass introduced by Patrick, who was the pupil of Germanus of Auxerre and Honoratus of Lerins, perhaps a Mass of the Gallican type. The 8th-century tract in Cott. MS. Nero A. II states that St. Germanus taught the "Cursus Scottorum" to St. Patrick. It is clear that the British mass introduced by David, Gildas, and Cadoc differed from it. The second and third orders used partly Patrick's mass and partly one of British origin, and in the case of the third order Roman modifications were also introduced.
The working of the "Catalogus" seems to imply that the first and second orders were Quartodecimans, but this is clearly not the meaning, or on the same argument the third order must have been partly Sextodecimans — if there were such things — and moreover we have the already mentioned statement of St. Wilfrid, the opponent of the Celtic Easter, at the Synod of Whitby, that such was not the case. Tirechan can only mean what we know from other sources: that the fourteenth day of the moon was the earliest day on which Easter could fall, not that it was kept on that day, Sunday or weekday. It was the same ambiguity of expression which misled Colman in 664 and St. Aldhelm in 704. The first and second orders used the Celtic tonsure, and it seems that the Roman coronal tonsure came partly into use during the period of the third order.
After that we have an obscure period, during which the Roman Easter which had been accepted in South Ireland in 626-28, became universal, being accepted by North Ireland in 692, and it seems probable that a Mass on the model of the Carlsruhe and Piacenza fragments and the Stowe and Bobbio Missals - a Roman Canon with some features of a non-Roman type - came into general use. It was not until the 12th century that the separate Irish Rite, which, according to Gilbert, Bishop of Limerick, was in use in nearly all Ireland, was abolished. Saint Malachy, bishop of Armagh, began the campaign against it, and at the Synod of Cashel, in 1172, a Roman Rite "juxta quod Anglicana observat Ecclesia" was finally substituted.

Scottish sources

In Scotland there is very little information. Intercourse with Ireland was considerable and the few details that can be gathered from such sources as Adamnan's Life of St. Columba and the various relics of the Scoto-Northumbrian Church point to a general similarity with Ireland in the earlier period. Of the rite of the monastic order of the Culdees very little is known, but they certainly had a rite of their own, which may have been similar to the Irish.
The Roman Easter and tonsure were adopted by the Picts in 710, and at Iona in 716-18, and much later, in about 1080, St. Margaret of Scotland, wife of King Malcolm III, wishing to reform the Scottish church in a Roman direction, discovered and abolished certain peculiar customs of which Theodoric, her chaplain and biographer, tells us less than we could wish.
It seems that the Scots did not begin Lent on Ash Wednesday but on the Monday following, as is still the Ambrosian practice. They refused to communicate on Easter Day and arguments on the subject make it seem as if the laity never communicated at all. In some places they celebrated Mass "contra totius Ecclesiae consuetudinem, nescio quo ritu barbaro". The last statement may be read in connection with that in the Register of St. Andrew's, "Keledei in angulo quodam ecclesiae, quae modica nimis est, suum officum more suo celebrant".
How much difference there may have been cannot be judged from these expressions. Scotland may have retained a primitive Celtic Rite, or it may have used the greatly Romanized Stowe or Bobbio Mass. The one fragment of a Scottish Rite, the Office of the Communion of the Sick, in the Book of Deer, probably 11th century, is certainly non-Roman in type, and agrees with those in the extant Irish books.
The Book of Deer is a 10th-century gospel book from Old Deer, Aberdeenshire, Scotland, with early 12th-century additions in Latin, Old Irish and Scottish Gaelic. Now in the Cambridge University Library. It contains part of an order for the communion of the sick, with a Gaelic rubric. The origin of the book is uncertain.

Irish (insular and continental) sources

In 590 St. Columbanus and his companions travelled to the Continent and established monasteries throughout France, South Germany, Switzerland, and North Italy, of which the best known were Luxeuil, Bobbio, St. Galen, and Ratisbon. It is from the Rule of St. Columbanus that we know something of a Celtic Divine Office. Irish missionaries, with their very strict rule, were not altogether popular among the lax Gallican clergy, who tried to get them discouraged. At a council at Macon, in 623, certain charges brought by one Agrestius were considered. Among them is the following: "In summâ quod a caeterorum ritu ac norma desciscerent et sacra mysteria sollemnia orationum et collectarum multiplici varietate celebrarent". There has been more than one interpretation of this phrase, some holding, with Pope Benedict XIV, that it refers to the use of many collects before the Epistle, instead of the one collect of the then Roman Missal, others that it implies a multiplicity of variables in the whole Mass, analogous to that existing in the Hispano-Gallican Rite. The Columbanian monasteries gradually drifted into the Benedictine Order.
The general conclusion seems to be that, while the Irish were not above borrowing from other Western nations, they originated a good deal themselves, much of which eventually passed into that composite rite which is now known as Roman. This seems to be a rough statement of the opinion of the English Roman Catholic scholar Edmund Bishop, which involves the much larger question of the origin and development of all the Western rites.

The Antiphonary of Bangor

Copied at the Abbey of Bobbio from a manuscript compiled at the monastery of Bangor in County Down, during the time of Abbot Cronan, this so-called "antiphonary" is now in the Ambrosian Library at Milan. It contains a large collection of canticles, hymns, collects, and antiphons, all, with very few exceptions, relating to the Divine Office. All but two of the twenty-one pieces in the Turin fragment are found in this manuscript also.

The [Bobbio Missal]

A manuscript of the 7th century found by Mabillon at Bobbio in North Italy, now in the Bibliothèque nationale at Paris. V. Neale and Forbes entitle it Missale Vesontionense seu Sacramentarium Gallicanum, its attribution to Besançon being due to the presence of a Mass in honour of St. Sigismund. Monseigneur Duchesne appears to consider it to be more or less Ambrosian, but Edmund Bishop considers it to be "an example of the kind of book in vogue in the second age of the Irish Saints", and connects it with the undoubtedly Irish Stowe Missal. It contains a Missa Romensis cottidiana and masses for various days and intentions, with the Order of Baptism and the Benedictio Cerei.

The Stowe Missal

The Stowe Missal is a manuscript of the late 8th or early 9th century, with alterations in later hands, most of them written by one Moelcaich, who signs his name at the end of the Canon, and whom Dr. MacCarthy identifies, not very convincingly, with Moelcaich MacFlann, c. 750. It was discovered abroad, in the 18th century, by John Grace of Nenah, from whom it passed to the Duke of Buckingham's library at Stowe. It was bought by the Earl of Ashburnham in 1849, and from his collection it went to the Royal Irish Academy. It contains part of the Gospel of St. John, probably quite unconnected with what follows, bound up with the Ordinary and Canon of the Mass, three Masses, the Order of Baptism and of the Visitation, Unction, and Communion of the Sick, and a treatise in Irish on the Mass, of which a variant is found in the "Leabhar Breac".
The non-Roman elements in the Stowe Missal are: The Bidding Litany between the Epistle and Gospel, which, however, came after the Gospel in the Gallican. The Post-Sanctus. the Responsory of the Fraction. The position of the Fraction before the Pater Noster. the elaborate Fraction. the Communion Antiphons, and Responsory. In the "missa apostolorum et martirum et sanctorum et sanctarum virginum", in the Stowe, the Preface and Sanctus are followed by a Post-Sanctus of regular Hispano-Gallican form, "Vere sanctus, vere benedictus"" etc., which modulates directly into the "Qui pridie"" with no place for the intervention of "Te igitur""and the rest of the first part of the Gelasian Canon. This may represent an Irish Mass as it was before the Gelasian interpolation. In the other two Masses this is not shown.

The Book of Dimma

An 8th-century Irish pocket gospel book originally from the Abbey of Roscrea, County Tipperary, Ireland. The Book of Dimma contains the four gospels and has an order for the unction and communion of the sick inserted between the gospels of Luke and John.

The Book of Mulling

The Book of Mulling is a manuscript of the late 8th century. It contains the four Gospels, an office for the unction and communion of the sick, and a fragmentary directory or plan of a service. Dr. Lawlor thought the latter a plan of a daily office used morning and evening but the editors of the Liber Hymnorum took it as a special penitential service and compared it with the penitential office sketched out in the Second Vision of Adamnan in the Speckled Book, which, as interpreted by them, it certainly resembles.
The service plan in the Book of Mulling is:
#
  1. Magnificat
  2. Stanzas 4, 5, 6 of St. Columba's hymn Noli pater
  3. A lesson from St. Matt. v
  4. The last three stanzas of the hymn of St. Secundus, Audite omnes
  5. Two supplementary stanzas
  6. The last three stanzas of the hymn of Cumma in Fota, Celebra Juda
  7. Antiphon Exaudi nos Deus, appended to this hymn
  8. Last three stanzas of St. Hillary's hymn, Hymnum dicat
  9. Either the antiphon Unitas in Trinitate or the hymn of St. Colman MacMurchon in honour of St. Michael, In Trinitate spes mea
  10. The Creed
  11. The Paternoster
  12. Illegible, possibly the collect Ascendat oratio.

    Liber Hymnorum - The Book of Hymns

This is a collection of forty hymns in Latin and Irish, almost all of Irish origin, with canticles and "ccclxv orationes quas beatus Gregorius de toto psalterio congregavit". There are explanatory prefaces in Irish or Latin to each hymn. Some of the hymns are found in the Antiphonary of Bangor, the Leabhar Breac, and the Book of Cerne. There are two manuscripts of this collection, not agreeing exactly, one in Trinity College, Dublin, of the 11th century, and one in the Franciscan Convent at Dublin, of somewhat later date.
In the "Liber Hymnorum" there are hymns by Patrick, Columba, Gildas, Sechnall, Ultan, Cummaim of Clonfert, Muging, Coleman mac Ui Clussaigh, Colman Mac Murchan, Cuchuimne, Óengus of Tallaght, Fiacc, Broccan, Sanctam, Scandalan Mor, Mael-Isu ua Brolchain, and Ninine, besides a few by non-Irish poets.

Fragmentary texts

The Turin Fragment is a manuscript of the 7th century in the Turin Library. Mayer considers the fragment to have been written at Bobbio. It consists of six leaves and contains the canticles, "Cantemus Domino", "Benedicite", and "Te Deum", with collects to follow those and the Laudate psalms and the "Benedictus", the text of which is not given, two hymns with collects to follow them, and two other prayers.
There are two Karlsruhe Fragments: four pages in an Irish hand of the late 8th or early 9th century in the Library of Karlsruhe contain parts of three masses, one of which is "pro captivis". The arrangement resembles that of the Bobbio Missal, in that the Epistles and Gospels seem to have preceded the other variables under the title of lectiones ad misam. Another four pages in an Irish hand probably of the 9th century contain fragments of masses and a variant of the intercessions inserted in the Intercession for the Living in the Stowe Missal and in Witzel's extracts from the Fulda Manuscript. There are also some fragments in Irish.
The Piacenza Fragment consists of four pages in an Irish hand, possibly of the 10th century. The two inner pages contain parts of three Masses, one of which is headed "ordo missae sanctae mariae". In the others are contained the Prefaces of two of the Sunday Masses in the Bobbio Missal, one of which is used on the eighth Sunday after the Epiphany in the Mozarabic.
The St. Gall Fragments are 8th- and 9th-century fragments in Manuscripts 1394 and 1395 in the Library of St. Gallen. The first book contains part of an ordinary of the Mass which, as far as it goes, resembles that in the Stowe Missal. The second contains the confession and litany, which also begin the Stowe Missal, a fragment of a Mass of the Dead, a prayer at the Visitation of the Sick, and three forms for the blessing of salt and water.
The Basle Fragment is a 9th-century Greek Psalter with a Latin interlinear translation. On a fly-leaf at the beginning are two hymns in honour of Mary and of St. Bridget, a prayer to Mary and to the angels and saints, and a long prayer "De conscientiae reatu ante altare".
The Zurich Fragment is a 10th-century leaf containing part of an office for the profession of a nun.

Other manuscripts

Besides these manuscripts there are certain others bearing on the subject which are not liturgical, and some of which are not Celtic, though they show signs of Celtic influences. The Book of Cerne is a large early 9th-century manuscript collection of prayers, etc. made for Æthelwold, Bishop of Lichfield. It once belonged to the Abbey of Cerne in Dorset, but is Mercian in origin and shows Irish, Anglo-Saxon, Carolingian, Roman, and Byzantine influences. The Leabhar Breac or Speckled Book, an Irish manuscript of the 14th century, belonging to the Royal Irish Academy, contains a very large collection of ecclesiastical and religious pieces in Irish. The contents are not as a rule of a liturgical character but the book contains a variant of the Irish tract of the Mass which is also in the Stowe Missal. An 8th-century manuscript of probably Northumbrian origin, contains selections from the Gospels, collects, hymns, canticles, private devotions, etc. A fragment of seven leaves of an Irish manuscript of the 9th century contains a litany, the Te Deum, and a number of private devotions.
The ultimate origin of the various prayers, etc., found in the fragments of the Irish Rite in the books of private devotion, such as the Book of Cerne, Harl. MS. 7635, and MS. Reg. 2. A. xx, which are either Irish or have been composed under Irish influence, is still under discussion.
The Turin Fragment and the Antiphonary of Bangor contain for the most part pieces that are either not found elsewhere or are only found in other Irish books.
The Book of Cerne is very eclectic, and pieces therein can also be traced the Gelasian, Gregorian, Gallican, and Hispanic origins, and the Stowe Missal has pieces which are found not only in the Bobbio Missal, but also in the Gelasian, Gregorian, Gallican, Hispanic, and even Ambrosian books.

Office and liturgy

Evidence as to the nature and origin of the Irish office is found in the Rule of St. Columbanus, which gives directions as to the number of psalms to be recited at each hour, in the Turin fragment and the Antiphonary of Bangor, which gives the text of canticles, hymns, collects, and antiphons, in the 8th century tract in Cott. MS. Nero A. II., which gives what was held in the 8th century to be the origin of the "Cursus Scottorum" and in allusions in the Catalogus Sanctorum Hiberniae, which differentiates between the Cursus Gallorum, which it derives imaginatively from Ephesus and St. John, through St. Polycarp and St. Irenaeus, and this Cursus Scottorum which, according to this writer, probably an Irish monk in France, originated with St. Mark at Alexandria. With St. Mark it came to Italy. St. Gregory of Nazianzus, St. Basil, and the hermits St. Anthony, St. Paul, St. Macarius, St. John, and St. Malchus used it. St. Cassian, St. Honoratus, and St. Porcarius of Lérins, St. Caesarius of Arles, St. Germanus, and St. Lupus also used it, and St. Germanus taught it to St. Patrick, who brought it to Ireland. There Wandilochus Senex and Gomorillus used it and St. Wandilochus and Columbanus brought it to Luxeuil. The part of the story from St. Germanus onwards may possibly be founded in fact. The other part is not so probable as it does not follow that what St. Columbanus carried to Gaul was the same as that which St. Patrick had brought from Gaul in an earlier age.

The Mass

The Bobbio and Stowe Missals contain the Irish ordinary of a daily mass in its late Romanized form. Many of the variables are found in the Bobbio book and portions of some masses are in the Carlsruhe and Piacenza fragments besides which a little information is found in the St. Gall fragments, the Bangor Antiphonary, the order for the communion of the sick in the Books of Dimma, Mulling, and Deer, the tract in Irish at the end of the Stowe Missal and its variant in the Leabhar Breac.
The Bobbio book is a complete missal, for the priest only, with masses for holy days through the year. The Stowe Missal gives three differing forms, a fragmentary original of the 9th century, the correction by Moelcaich and the Mass described in the Irish tract. The pieces said by the people are in several cases only indicated by beginnings and endings. The original Stowe Mass approaches nearer to that of Bobbio than the revised form does.
Moelcaich's version is a mixed mass, Gelasian, Roman or Romano-Ambrosian for the most part, with much of a Hispano-Gallican type underlying it, and perhaps some indigenous details. It is evident that Roman additions or substitutions were recognized as such.
In the Bobbio book the Masses throughout the year seem to be Gallican in arrangement up to the Preface and Gelasian Roman afterwards. They contain at their fullest, besides Epistle, Gospel and sometimes a lesson from the Old Testament or the Apocalypse, the following variables:
  1. Collects, sometimes called Post Prophetiam, sometimes not named.
  2. Bidding prayer, sometimes called by its Gallican name, Praefatio. This is followed by one or more collects.
  3. Collect post nomina.
  4. Collect Ad Pacem.
  5. Sometimes secreta, but whenever this title is used the mass is wholly Roman and has no Praefatio, Post nomina or Ad Pacem, but only one collect preceding it.
  6. Contestatio, in one case called "immolatio missae". This is the Praefatio in the Roman sense.
Here the mass ends, with apparently no variable post-communion, though these are given in the three masses in the Stowe. The masses are: three for Advent; Christmas Eve and Day; St. Stephen; Holy Innocents; Sts. James and John; Circumcision; Epiphany; St. Peter's Chair; St. Mary; the Assumption ; five for Lent; In symboli traditione; Maundy Thursday; Easter Eve and Day; two Paschal Masses; Invention of the Cross; Litany days; Ascension; Pentecost ; St. John Baptist; in S. Johannis passione; Sts. Peter and Paul; St. Sigismund; Martyrs; one Martyr; one Confessor; St. Martin; one Virgin; for the Sick; Dedication; St. Michael; for travellers; for the priest himself; Missa omnimoda; four votive masses; for the Living and the Dead; in domo cujuslibet; seven Sunday Masses; for the king; two daily Masses; for a dead priest; for the Dead—sixty-one in all.
The mass in symboli traditione includes the traditio and expositio symboli, that for Maundy Thursday is followed by the Good Friday Lectio Passionis, and the Easter Eve mass is preceded by preces and intercessory orationes similar to those now used on Good Friday, by the benedictio cerei, here only represented by Exultet, and by the order of baptism.

Hours and psalms

The Rule of St. Columbanus and the Bangor book distinguish eight Hours;
  1. Ad duodecimam
  2. Ad initium noctis
  3. Ad nocturnam or ad medium noctis
  4. Ad matutinam
  5. Ad secundam
  6. Ad tertiam
  7. Ad sextam
  8. Ad nonam
At the four lesser Hours St. Columanus orders three psalms each; at Vespers, ad initium noctis, and ad medium noctis twelve each, and ad matutinam, a very curious and intricate arrangement of psalmody varying in length with the longer and shorter nights. On Saturdays and Sundays from 1 November to 25 March, seventy-five psalms were recited on each day, under one antiphon for every three psalms. From 25 March to 24 June these were diminished by three psalms weekly to a minimum of thirty-six psalms. It would seem, though it does not say so, that the minimum was used for about five weeks, for a gradual increase of the same amount arrives at the maximum by 1 November. On other days of the week there was a maximum of thirty-six and a minimum of twenty-four.
The Rule does not say how the psalter was distributed, but from the Bangor book it seems that the Laudate psalms were said together, doubtless, as in all other rites, Eastern or Western, at Lauds, and that Domine, Refugium was said ad secundam. Adamnan mentions that St. Columba sang Ps. xliv, Eructavit cor meum, at vespers on one occasion. The psalms at the lesser Hours were to be accompanied by a number of intercessory versicles. In the Bangor book these, somewhat expanded from the list in the Rule, but certainly to be identified with them, are given in the form of one, two, or three antiphons and a collect for each intercession.

Baptism service

There are two Irish orders of baptism extant: one in the 7th-century Bobbio Missal and one in the 9th-century part of the Stowe Missal. They differ considerably in the order of ceremony, though they have a good deal of their actual wording in common. Both the Stowe and the Bobbio have the Gallican washing of the feet after baptism, with words very similar to those in the "Gothicum" and "Vetus Gallicanum".
The Stowe is the longest of any early form and on the whole has most in common with the Gelasian and Gregorian. In some of its details it has the appearance of a rather unskilful combination of two orders, for the exorcism, renunciation and confession of faith come twice over. The long Blessing of the Font and Baptismal Water is a combination of the Gelasian and Gregorian forms.
The actual formula of baptism is not given in the Stowe, but in the Bobbio it reads: "Baptizo te in nomine Patris et Filii et Spiritus Sancti unam habentem substantiam ut habeas vitam aeternam partem cum sanctis." This form resembles those in the "Missale Gothicum", the "Vetus Gallicanum" and the 11th-century Mozarabic "Liber Ordinum" in adding "ut habeas vitam aeternam", though all differ in other additions.

Bobbio form

There are four extant specimens of these services: in the Stowe Missal and the Book of Dimma are the longest and most complete, and agree very closely. The Mulling differs in the preliminary bidding prayers and in beginning with blessings of water and of the sick person, the latter of which comes at the end and in a different form in the Stowe and Dimma, though it agrees with the Dimma in inserting the creed, which is not in the Stowe. The Deer form has only the communion, which agrees substantially with the other three. The order in the Stowe is:
In the Leabhar Breac there is a tract describing the consecration of a church, a ceremony divided into five parts; consecration of the floor, of the altar with its furniture, consecration out of doors, aspersion inside and aspersion outside. The consecration of the floor includes writing two alphabets thereon. There are directed to be seven crosses cut on the altar, and nothing is said about relics.
On the whole the service appears to be of the same type as the Roman though it differs in details and, if the order of the component parts as given in the tract may be taken as correct, in order also.
