Homilies on the Psalms

The Tractatus in Psalmos are homilies that Jerome preached in Latin to the monastic community he led at Bethlehem around the turn of the fifth century. They were not composed for publication; they were taken down as he spoke, which is why they read nothing like his polished commentaries or his combative letters. The listeners were monks, some of them recent arrivals from the West, gathered for the daily office, and Jerome works through the psalm they have just sung, verse by verse, before sending them back to their cells. The collection circulated for centuries under other names until the Benedictine scholar Germain Morin identified Jerome as the preacher and published the homilies in the 1890s. More recently the recovery of a Greek manuscript containing Origen's homilies on several of the same psalms has shown how closely Jerome was following the Alexandrian master, often translating and adapting him on the spot even while publicly denouncing Origenism elsewhere.

The method is consistent across the series. Jerome takes the Latin text his monks know, pauses to note where the Hebrew or the Greek says something different, and then moves to the spiritual sense, reading the psalm as the voice of Christ, of the Church, or of the soul under discipline. He is unembarrassed about allegory: the mountains are the prophets and apostles, the enemies are demons and heretics, the waters are baptism or the turbulence of the passions. But the allegory is in service of exhortation. Again and again he turns from the verse to the monk in front of him, warning against pride in fasting, against gossip, against the fantasy that leaving the world has already made one holy. He attacks Arians, Manichaeans, and those who follow Origen too far, and he speaks about the Jews with the hostility typical of his age. The homilies also preserve small details of the Bethlehem liturgy and of Jerome's own temperament: his impatience, his delight in a Hebrew etymology, his insistence that the psalms are prophecy and not merely poetry.

The work matters because it shows the patristic reading of the Psalter at street level, so to speak, as it was actually delivered to people who prayed these texts every day. It is also the clearest window we have into how Origen's exegesis was transmitted into the Latin monastic world, and into the gap between Jerome's public polemic and his private practice as a teacher. For anyone trying to understand why the Psalms became the backbone of Western monastic prayer, these sermons explain the habit of mind that made every psalm a Christological and ascetical text at once.

Who should read this: those who already pray the Psalms regularly and want to hear how a fourth-century monk heard them, and students of patristic exegesis interested in Origen's Latin afterlife. It is not for readers looking for a systematic commentary or for an introduction to Jerome; his letters and the prefaces to his biblical translations are the better entry points, and the allegorical method here will frustrate anyone who wants historical exposition of the psalms themselves.
