Sentences
Libri Quattuor Sententiarum — the standard theological textbook of the medieval university
Tradition: Latin scholastic theology
The master framework of medieval theology — four books, four centuries of commentary, every scholastic mind compelled to engage
The Four Books of Sentences is the most influential theological textbook ever written. Peter Lombard compiled and organised patristic opinions (sententiae) — principally from Augustine, but also from Ambrose, Jerome, Hilary, John of Damascus, and the Victorines — on the whole of Christian doctrine. Book I treats God and the Trinity; Book II treats creation, angels, the fall, grace, and sin; Book III treats the Incarnation, the virtues, and the Decalogue; Book IV treats the sacraments and the last things. The work was adopted as the standard theology textbook at Paris and remained so until the sixteenth century. Over 1,400 commentaries are known: every major scholastic theologian — Albert the Great, Bonaventure, Thomas Aquinas, Duns Scotus, William of Ockham, Gabriel Biel — wrote one as a rite of passage. The Sentences did not impose a single position on any disputed question; its genius was to frame the questions so clearly that all subsequent debate was conducted within its structure.

School Embodiments
The Sentences created the institutional and intellectual framework of scholastic theology. The commentary tradition it generated is the single largest body of systematic theology in Western history.
"In this work we have brought together the opinions (sententiae) of the Fathers … to save the reader the trouble of searching through many volumes." (Sentences, Prologue)
Augustine is the dominant authority throughout — cited more than any other Father. The Sentences ensured that Augustinian theology remained the backbone of Western scholastic thought.
"As the blessed Augustine says …" (recurrent formula throughout the four books)
Lombard's sacramental definitions — especially the definition of a sacrament as a "sign of a sacred thing" — became the foundation for Aquinas's sacramental theology in the Summa.
"A sacrament is properly so called because it is a sign of the grace of God and a form of invisible grace." (Sentences IV, d.1, ch.4)
The Sentences represents the broad centre of Latin Christian doctrinal tradition — ecumenical in patristic sources, moderate in disputed questions.
"We desire to set forth the opinions of the holy Fathers concerning these matters, briefly and clearly." (Sentences, Prologue)
Internal Tensions
Lombard's refusal to resolve many disputed questions was his pedagogical genius and his theological vulnerability. His identification of charity with the Holy Spirit (Sentences I, d.17) was rejected by Aquinas and most later commentators. One of his Trinitarian opinions was condemned at the Fourth Lateran Council (1215). The question of whether the Sentences imposes a framework that distorts the patristic sources it compiles has been raised by modern scholars.
I. Time
The standard Augustinian temporal framework: created time, linear history from creation through fall and redemption to Last Judgement. God's eternity transcends time. Non-deterministic: human free will affirmed alongside divine predestination, following Augustine.
Attributes
II. Space
Finite, created, three-dimensional. The theological geography of heaven, hell, and purgatory matters more to Lombard than the physics of space. The standard medieval cosmos is assumed.
Attributes
III. Matter
Created from nothing, good, hylomorphic. The sacraments are material signs that convey spiritual grace — a doctrine that depends on the goodness and theological transparency of the material order.
Attributes
IV. Observer
The human person is a rational soul united to a body, created in the image of God, fallen through original sin, redeemed through Christ. The ultimate metaphysical agent is a personal Trinitarian God. Lombard follows Augustine on the soul's Trinitarian image (memory, intellect, will).
Attributes
V. Energy
Not theorised independently. Finite, conserved, irreversible in the inherited patristic-Aristotelian framework.
Attributes
VI. Information
The divine ideas are the eternal archetypes of all created things (Sentences I, d.35–36, following Augustine). Knowledge participates in divine illumination. Personal conservation guaranteed by bodily resurrection (Sentences IV, d.43–50).
