Origen was born in Alexandria around 185 to Christian parents. His father was martyred during the persecution of Septimius Severus, and teenaged Origen was prevented from joining him by his mother. He went on to become a catechist at the school in Alexandria and continued to study and teach for the rest of his life, travelling around the Mediterranean on several occasions. He became famous as a ‘Christian philosopher’ and was respected in the church as its foremost theologian. During his career he wrote around 6,000 monographs, ranging in subject from philosophy to textual criticism to homiletics, apologetics, and Christian ethics. His theology made important contributions to trinitarianism. He died shortly after being released from prison during the Decian persecution, having kept the faith through severe torture.
