Life and Historical Setting

Justin was born in Roman Palestine and describes a search through philosophical schools before embracing Christianity. He taught in Rome and was executed with companions after examination by the prefect Rusticus.12

Work and Contribution

His Apologies defend Christians against rumor and explain baptism, Eucharist, Sunday worship, ethics, and belief in Christ as Logos. The Dialogue frames a sustained, sometimes adversarial argument over Scripture with a Jewish interlocutor.23

Reception and Influence

Later apologists drew on Justin's effort to relate biblical faith to Greek philosophy. His descriptions of worship remain major evidence for second-century Christian practice.34

Evidence, Debate, and Interpretation

Justin's account of Judaism reflects Christian competition and must not be treated as a neutral report of Jewish belief. The authenticity of works transmitted under his name varies, and only a core group is generally accepted.45
