The discovery and critical edition (2015) of Origen’s Homilies on the Psalms were one of the most important events of patristic scholarship of the last years. The text of these twenty-nine homilies sheds new light on various aspects of the Alexandrian master’s oeuvre. The aim of my research project is to study the theology of Origen’s Homilies on the Psalms in its wide context. Principal tasks are the registration of the similarities and differences of the thoughts in relation to the Homilies of the Psalms and the other Origenian works and the analysis of these ideas. There are two pillars of the project: theology in its narrow sense and theological anthropology connected to theologia moralis. The focal point of the first theme is the relation between natural theology and theologia revelata. The study of the second topic focuses on the source and the role of rational thinking and irrational instincts in Origen’s thought.
