Origen of Alexandria, one of the earliest and most influential Christian thinkers, crafted On First Principles (Peri Archon) as the first systematic theology in Christian history. Written in the early third century, this groundbreaking work explores the fundamental questions of faith: the nature of God, the structure of creation, the preexistence and destiny of the soul, the interpretation of Scripture, and the ultimate purpose of salvation.
In On First Principles, Origen combines rigorous philosophical reasoning with deep spiritual insight. He presents God as supremely transcendent yet relational, reveals the moral and metaphysical dimensions of human freedom, and articulates a vision of salvation rooted in divine justice and mercy. His methodical approach to Scripture—distinguishing literal, moral, and allegorical senses—set a precedent for Christian exegesis for centuries to come.
 
While some of Origen’s views were later debated or deemed controversial, his intellectual ambition and pastoral concern remain striking. This edition offers careful annotations, clarifying historical context, textual sources, and complex passages, making this seminal work accessible to modern readers.
 
Engage with Origen’s enduring vision, where faith, reason, and devotion converge. On First Principles invites readers to explore the origins of Christian theological thought and the profound questions that continue to shape spiritual reflection today.
