ΤΗΕ PSALTER is the most well-known liturgical book of the Church. It is used every day at every divine service (Vespers, Orthros, the Hours, etc.), including the recitation of complete Psalms, or select verses, at the Divine Liturgy and all other Holy Mysteries. Indeed, the entire hymnology of the Church is founded upon the Psalter.
All of the saints loved to read the Psalter. The most recent of the Cappadocian saints, Saints Arsenios and Paisios, however, also used it as a kind of Euchologion (Prayer Book). Saint Arsenios, began to use the Psalms in response to believers who requested his spiritual assistance for situations not addressed in the Euchologion itself. He appointed an individual Psalm for every prayerful request, based upon the original meaning of the Psalm.
St. Paisios also regularly used the Psalter. He said that “the Psalms are thunder and lightning to the devil.” “When you read from the Psalter during difficult situations, you feel relief, vindication, and confidence that God will help you.” During the final years of the Saint’s life, his prayer for the world was primarily offered with the assistance of the Psalter, which he had split into three sections, and from which he read one per day. His prayer was based upon the work of St. Arsenios.
This book is a kind of prayer book, based upon the Psalter. A particular prayerful need is prescribed at the beginning of every psalm, based upon the earlier work of St. Arsenios. In addition, a parallel need / explanation from St. Paisios the Athonite has been added. Αdded to the end of each Kathisma are three toparia and a prayer.
This book is a publication of the Cell of St. John the Theologian, Koutloumousiou Monastery, Mt. Athos, published under the spiritual guidance of Hieromonk Gregorios and with the assistance of the fathers of the Cell.
