The Liturgical Psalter

Praying the Psalter

Psalter of David: Introduction

[Note: the numbers between square brackets in the text are footnotes at the bottom of this article.
i.e. [1] is footnote 1]

The Psalms are a central feature of Christian worship, a practice we inherited from our Jewish forebears. The Psalms are used in a variety of ways liturgically in the Eastern Churches. The fixed cycle of daily services has certain Psalms assigned to them.Certain Psalm verses are assigned to specific functions during the services. The Psalter is read once per week distributed through these services. The Psalter is also one of the most commented on books of the bible by the fathers. [1]

It was indeed for this reason that he (Christ) made this (righteous actions) resound in the Psalms before his sojourn in our midst, so that just as he provided the model of the earthly and heavenly man in his own person, so also from the Psalms he who wants to do so can learn the emotions and dispositions of the souls, finding in them also the therapy and correction suited fo each emotion.

Athanasius, Letter to Marcellius [2]

Indeed, the fathers of the second council of Nicea decreed that any bishop must have memorized the Psalter.

When we recite the Psalter, we promise God: I will meditate upon they statutes, and will not forget they words. It is a salutary thing for all Christians to observe this, but it is especially incumbent upon those who have received the sacerdotal dignity. Therefore we decree, that every one who is raised to the rank of the episcopate shall know the Psalter by heart, so that from it he may admonish and instruct all the clergy who are subject to him.

Canon II, Second Council of Nicea

The Psalter is the source of Christian prayer and instruction. The reason the Psalter forms the backbone of liturgical prayer is for this value to admonish and instruct us. By our constant encounter with this word of God in prayer we become like God.

Psalm numbering

The numbering of Psalms in worship for the Catholic and Orthodox churches follows the Greek Septuagint scheme rather than the Hebrew numbering used by Jews and Protestants. The liturgical system outlined here is based on the Greek numbering scheme.

If you are unsure about which numbering scheme is in use in your bible, turn to Psalm 50. In the Greek version this is titled the great penitential Psalm of David when he was confronted by Nathan beginning Have mercy on me O GodÉ. If instead, Psalm 50 is titled as the Psalm of Asaph beginning The mighty One, God the LordÉ your Bible has a Hebrew numbering scheme.

The table below shows the conversion of Psalm numbers from one version to the other. Many modern Bibles will show the second number in parenthesis after the primary number of a Psalm. As you can see by this list, if the primary number is lower than the secondary one, you have the Greek numbering scheme.

Greek Hebrew Greek Hebrew
1-8 1-8 114-115 116
9 9-10 116-145 117-146
10-112 11-113 146-147 147
113 114-115 148-150 148-150

In addition to the numbering of the Psalms, there are some differences in the text of the Psalms between the Hebrew and Greek versions as well. [3]


The liturgical Psalter in the Eastern Church is divided into twenty sections called the Kathismata [4], from the Greek term meaning to sit. Originally, this was likely a rubric indicating that the congregation may be seated during the singing of the hymns closing each section of the Psalter. The name kathisma was originally applied just to those closing prayers. We see this in the earliest extant Psalter where the twenty divisions are marked, but the name kathisma appears for the poetry chanted after the division. [5] Each Kathisma is divided into three stations. [6] There is an attempt to keep each of these divisions roughly equal and keep the thematically related material together at the same time. All of the Psalm numbering in these tables is by the Greek system (see the previous section).

With the division of the text into Kathismata and stations, there are three points of special prayers: the opening of any reading of the Psalter, the end of each station, and the end of each Kathisma.

Opening a session taken outside of another service would consist of the normal beginning prayers. These are concluded with the standard troparia of forgiveness and a special prayer to the Trinity on the psalter. Each station is concluded with a standard doxology and a triple alleluia with a glory repeated three times and concluded with another doxology. Each kathisma has a different set of ending prayers in the liturgical Psalter. There are several Psalters with these prayers noted in the Printed editions of Psalters section below.

Kathisma 1 Kathisma 2
Station 1 1-3 Station 1 9-10
Station 2 4-6 Station 2 11-13

Order of Psalter Readings

The Kathismata are distributed across the liturgical services of the week so that the complete Psalter is read once a week normally, and twice a week during the Great Fast. [10] These charts detail the complete liturgical cycle for the Psalter readings. As a practical matter, most small monasteries and parish churches do not follow this full cycle. In fact, the readings from a Kathisma are among the first sections of matins & vespers to be cut for the sake of brevity. Even those services that still include the reading of the Kathismata appointed usually only take a small sample of what is indicated by these charts.

Thomas Sunday — September 21 | December 20 —January 14 [11]

Sun Mon Tue Wed Thurs Fri Sat
Matins 2, 3, 17 or Polyelei [12] 4, 5 7, 8 10, 11 13, 14 19, 20 16, 17

During the Great Fast the reading of the Psalter is doubled, so that we read the entire Psalter twice a week during the liturgical services. This expands the scheduled readings of the Kathismata to the hours.

The Great Fast Week 5

9th Hour 9 18 [19] 6 12
Vespers 10 19 7 18 1

During the 5th week of the Great Fast we celebrate the Matins of St. Andrew of Crete on Thursday morning, (or transferred to Wednesday night). This is a long penitential canon at Matins. As a result the Psalter readings for the week are redistributed to compensate.

Holy Week

6th Hour 8 3 20
9th Hour
Vespers 18 18 18

Presanctified liturgies are celebrated on Monday, Tuesday and Wednesday of Holy Week. From here we take our leave of the Psalter until Matins of Thomas Sunday. So for half of Holy Week and all of Bright week we have no readings from the Psalter.

Biblical Canticles

The biblical canticles are part of the matins service. Originally the canticles or odes were sung alone. Eventually composed stanzas were made to supplement the biblical odes for each of the feasts and Sundays. The composed verses would play off a theme or item in the biblical ode and add material on the day ‘s celebration. These composed stanzas then replaced the singing of the biblical odes themselves entirely.

Liturgical Psalters generally include the biblical odes as well. These are the biblical odes and their arrangement for use in matins.

Ode 1 Ode 2 Ode 3
Song of MosesExodus 15:1-8 Song of MosesDeuteronomy 32:1-43 [20] Prayer of Anna1 Kings 2:1-10 [21]

Hately, Thomas L., ed. The Book of Psalms and Sacred Harmonies with Translations and Paraphrases. Edinburgh: Johnstone & Hunter, 1854.

This English Psalter using the text of the King James version of the bible is published in an unusual split page format. The pages are literally cut in half. The bottom half contains psalm tones with attribution to specific churches (there are 220 Psalm tones). The top half is the text of the psalms themselves. The idea is that one can keep the psalm tone open on the bottom to any text of psalm at the top desired. After the Psalms are a series of paraphrase hymns based on biblical texts. The hymns are done in the style of Psalms with content from throughout the Old & New Testaments. An index lists all the Psalm tones in groupings by character. A second index recommends particular tones for each Psalm or hymn in the book. There is a license notice at the opening of the book from Her Majesty’s Patent office authorizing the publication of this Psalter.

Zeedick, Peter Ivan, ed. Psaltir. Homestead, PA: Greek Catholic Union, 1921.

This is primarily a Church Slavonic Psalter in Cyrillic. The introduction in Church Slavonic gives the charts assigning the kathismata to the liturgical cycle and a brief description for taking the Psalms. The prayers for beginning the Kathisma reading are here and the prayers after each Kathisma, all in Church Slavonic. The Psalms are divided into the Kathismata and stations. There is a parallel column English text for the Psalms printed in the main text. The English is from the Douay translation of the Bible.

[4] Kathismata is plural the singular is Kathisma

[5] The Psalter manuscript is Lenigrad 216 dated to 862 Miguel Arranz, “Les grandes ≥tapes de la liturgie Byzantine: Palestine-Byzance-Russie. Essai d’per≠u historique,” Liturgie de l’≥glise particuli≤re et liturgie de l’≥glise universelle Bibliotheca Ephemerides liturgicae, Subsidia, no. 7 (1976). As cited in, Robert F. Taft, “Mount Athos: a late chapter in the history of the Byzantine Rite,” DOP, no. 42 (1988).

[6] The Greek Stasis (stasi”) can also mean standing. This contrasts with the sitting rubric inherent in the title of the Psalter closing prayers. In later monastic usage the Stylites adopt the term for their mode of life. See G. W. H. Lampe, A Patristic Greek Lexicon (Oxford: Clarendon Press, 1961), 1251.

[7] This is the Stepenni or Gradual Psalms, 119 — 133. In the Jewish tradition these are the Psalms sung by pilgrims on their way to Jerusalem. Festal Matins contain the Gradual Antiphons composed based on these Psalms. They are taken at festal Matins services prior to the reading of the Gospel. These are sung to a special set of melodies in the Carpatho-Rusyn tradition.

[8] Some Psalters end the first Station at verse 93 instead. This verse is sung three times in tone five on the 2nd, 3rd, & 4th Saturdays of the Great Fast (commemoration of all the departed). I will never forget thy precepts; for by them thou hast given me life. This verse marks the mid-point of the Psalm.

[9] Psalm 151 is in the Greek Psalter, but not in the Hebrew, is included at the end of many liturgical Psalters. But this Psalm is never part of the 20th Kathisma.

[10] The Great Fast is commonly called Lent in the Latin tradition. This is the forty-day fast prior the Pascha (Easter in the west).

[11] Thomas Sunday is the Sunday after Pascha (Easter). The week between Pascha and Thomas Sunday is known as Bright week.

[12] Polyelei is Psalm 134-35. These are sung to a special melody when appointed to be sung at a festal matins.

[13] The Sunday of the Prodigal son is two weeks before the start of the Great Fast. Note that in the Orthodox Liturgical calendar, the Great Fast begins on Monday, not Wednesday. The other time of change is September is keyed to the feast of the Holy Cross. This is the same time that the change in the Gospel reading cycle from Matthew to Luke occurs in the liturgical calendar (Lukan Jump). The feast of the exaltation of the Holy Cross on September 14 is the key feast for this shift. This change in readings of the Psalter in September is not followed on Mount Athos and those that follow their lead. Instead, they continue with the first version from Thomas Sunday until the Sunday of the Prodigal son.

[14] Polyelei is Psalm 134-35. These are sung to a special melody near the end of Matins.

[15] The Great Fast begins on a Monday, not a Wednesday. The forty days are counted from Monday until the Friday before Palm Sunday. There are six full weeks of the fast and the change in these readings would occur on the Monday of the cycle. The fast for Holy Week is separate from the Great Fast.

[16] Polyelei is Psalm 134-35. These are sung to a special melody.

[17] During the Great Fast the Presanctified Divine Liturgy is celebrated on Wednesday and Friday evenings instead of vespers. The Presanctified is a vespers service with communion that has been consecrated on the previous Sunday, hence the name Presanctified. Celebration of the Divine Liturgy (what the Latin tradition calls Mass) is prohibited on weekdays during the Great Fast. The Presanctified Liturgy provides the faithful with communion without breaking the liturgical character of the fast by the joyous celebration of the Divine Liturgy. For more detail on the liturgical season of the Great Fast see, Alexander Schmemann, Great Lent: Journey to Pascha, Rev ed. (Crestwood, NY: St. Vladimir Seminary Press, 1974), 45-62.

[18] Polyelei is Psalm 134-35. These are sung to a special melody.

[19] Because of the canon of St. Andrew on Wednesday night or Thursday morning, a Presanctified Divine Liturgy may be celebrated on Tuesday evening this week. If the Presanctified is celebrated then Kathisma 18 is moved from the ninth hour to Presanctified.

[20] Ode two is only taken on Tuesdays during the Great Fast. Thus ode two does not even exist in most composed canons.

[21] There are four books of Kings in the Greek Old Testament. In the Greek 1 & 2 Kings is equivalent to 1 & 2 Samuel from the Hebrew version, 3 & 4 Kings in the Greek are 1 & 2 Kings in the Hebrew version.

[22] Theotokos is a Greek term coined by the 4th ecumenical council from the words god and bearer. This becomes the centerpiece of the debate over Mary’s role in giving Christ flesh.

This book has become the classic explanation of the liturgical experience of the Great Fast. Father Alexander clearly explains the change in our attitude in prayer that needs to accompany the change in liturgical practice during the Great Fast. He briefly covers the development of liturgical practice, the readings encountered and the rational for these in our preparation for Pascha. The appendix of this volume is his call for renewal in our approach to communion as a church.
