Origen

According to the historian Eusebius of Caesarea, Origen’s father, Leonides, was martyred in the Christian persecution of 202, he was a pupil of Clement of Alexandria, whom he succeeded as head of the Catechetical school under the authority of the bishop Demetrius. Origen’s main lifework was on the text of the Greek Old Testament and on the exposition of the whole Bible.  Origen’s exegetical writings consist of commentaries (scholarly expositions for instructed Christians), homilies for mixed congregations, and scholia (detached comments on particular passages or books). Saint Jerome initially supported Origen, but turned against him as a heretic.
