The Psalter (also known as the Psalms of David) is the Old Testament book that contains hymns and poems traditionally ascribed to the Holy Prophet and King David, ancestor of our Lord Jesus Christ. Virtually every aspect of worship—praise, thanksgiving, penitence, intercession—is covered in the Psalter.
The Psalter in Orthodox worship
Fr. Georges Florovsky has described the Psalter as a golden thread running through the beautiful garment that is the divine services of the Orthodox Church. Indeed, the Psalter forms the core of each of the services of the Daily Cycle, the Divine Liturgy, and the other sacramental offices of the Church.
The Psalter is so prevalent in Orthodox worship that St. John Chrysostom said that wherever one looks in the Church, he finds the Psalter "first, last, and central."
Structure of the Psalter
Chapter Divisions—Septuagint vs. Masoretic Text
The Septuagint (LXX) is the version of the Old Testament used by the Orthodox Church. The LXX Psalter differs in several respects from Masoretic text (MT), which forms the basis for the King James Version and most modern English translations of the Bible.
In addition to substantive, textual differences, the LXX and MT versions of the Psalter differ most obviously in their chapter divisions. This can cause confusion to readers who do not understand the differences between the two versions.
The chapter divisions of the LXX and MT versions of the Psalter correspond as follows:
The Psalter is divided into 20 kathismata. Each kathisma is further divided into three stases. Each stasis contains between one and three chapters. The exception to this is Psalm 118. Due to its great length, this chapter constitutes the entire XVIIth Kathisma.
Each of the divine services contains fixed portions of the Psalter that are read or chanted each time the service is celebrated. In addition, certain services of the Daily Cycle contain prescribed kathisma readings. These prescribed readings rotate daily so that outside of Great Lent the Psalter is read through once in its entirety in a single week.
During the lenten fast, the kathisma readings are accelerated so that the Psalter is read through in its entirety twice each week.
