The Psalter has served as the Christian Church's primary prayer book since its earliest decades. The early Church inherited the Psalms from Jewish synagogue worship, and the Desert Fathers made them the backbone of their daily offices — Cassian describes monks chanting psalms through the night while performing manual labor. Athanasius of Alexandria, in his Festal Letters (329 AD), defined the feast itself in terms of Psalm-prayer: "For what else is the feast, but the service of the soul? And what is that service, but prolonged prayer to God, and unceasing thanksgiving?" He also read Psalm 2 as a prophetic guide: had the persecutors of Christ understood the Psalms, they would have recognized the Spirit's own words warning them. Augustine's Expositions on the Psalms (begun c. 392 AD) gave the Western tradition its deepest account of why the Psalms are uniquely suited to prayer: they are Scripture that speaks from inside the human soul, not merely to it. Where other biblical books address us, the Psalms voice our own experience back to us — grief, dread, praise, complaint, trust — providing language for what we feel but cannot express. His Letter to Marcellinus makes the point explicitly: in other books you are the hearer; in the Psalms, you are the speaker. The medieval tradition formalised Psalm-singing in the Divine Office, and the Reformers — Calvin's Genevan Psalter, Owen's expositions, Spurgeon's Morning and Evening — kept the Psalter central to Protestant piety as the school of prayer.
What the primary sources show
"For what else is the feast, but the service of the soul? And what is that service, but prolonged prayer to God, and unceasing thanksgiving" — Athanasius defines Christian festal life as extended Psalm-prayer and thanksgiving: the feast is not an external ritual but the soul's sustained orientation toward God.
"For Thou wilt bless the just man — This is blessing, to glory in God, and to be inhabited by God. Such sanctification is given to the just. But that they may be justified, a calling goes before: which is not of merit, but of the grace of God" — Augustine reads Psalm prayer as graced response to God's prior call, transforming recitation into living communion.
