This research investigates the philosophical concept of matter as developed by Augustine in Book XII of the *Confessions*, focusing on his interpretation of “heaven and earth” (*caelum et terram*) in the opening verses of Genesis. It examines how Augustine adopts and reworks the concept of matter (*hylé*) within both the intelligible and sensible realms. Special attention will be given to possible Neoplatonic sources, particularly Plotinus’s *Ennead* II.4 \[12], as well as to Christian exegetes such as Ambrose, Origen, and Basil of Caesarea. The study aims to clarify the conceptual status of matter in Augustine’s thought, identifying its sources, original contributions, and how it compares with Neoplatonic and Patristic traditions. The methodology is bibliographic and comparative, with a qualitative approach. The research also explores how metaphysical speculation and scriptural interpretation are intertwined in Augustine’s exegesis, revealing the philosophical richness of his theology. By highlighting Augustine’s synthesis of classical philosophy and Christian doctrine, the study seeks to contribute to contemporary debates in philosophy and theology.
