Early Theologians

On First Principles, Against Celsus & the Commentaries

Origen of Alexandria · c. 220 – 250

Historical Context

Origen was the most learned biblical scholar and speculative theologian of the third century, teaching first at Alexandria and later at Caesarea Maritima.

Summary

On First Principles is the first attempt at a systematic Christian theology; Against Celsus is a vast reasoned reply to a pagan philosopher; his commentaries and homilies shaped Christian exegesis for centuries. Some of his speculative views (preexistent souls, apokatastasis) were later condemned, but his exegesis and ascetic spirituality remained foundational.
