on Chrysostom were preserved by Photius (codex 273). Apologetic, historical Among apologetic writings was the Ad quaestiones magorum (429-436), now lost, in which Theodoret justified the Old Testament sacrifices as alternatives in opposition to the Egyptian idolatry, and exposed the fables of the Magi who worshipped the elements (Church History v. 38). De providentia, or Ten Discourses on Providence, consists of apologetic discourses, proving the divine providence from the physical order (chapters i-iv), and from the moral and social order (chapters vi-x). They were most probably delivered to the cultured Greek congregation of Antioch, sometime between 431 and 435. Unlike most sermons, they are reasoned arguments, lectures rather than homilies on scriptural texts. The Graecarum Affectionum Curatio or Cure of the Greek Maladies, subtitled The Truth of the Gospel proved from Greek Philosophy, arranged in twelve books, was an attempt to prove the truth of Christianity from Greek philosophy and in contrast with the pagan ideas and practises. As such, it forms one of the last Apologies written, since in an age when Christianity was dominant, the need for apologies gradually died out. The truth is self-consistent where it is not obscured with error and approves itself as the power of life; philosophy is only a presentiment of it. This work is distinguished for clearness of arrangement and style. The Ecclesiastical History of Theodoret, which begins with the rise of Arianism and closes with the death of Theodore in 429 (despite being completed in 449–450) is very different in style from those of Socrates Scholasticus and Sozomen. It contains many sources otherwise lost, specially letters on the Arian controversy; however, the book is extremely partisan, the heretics being consistently blackened and described as afflicted with the 'Arian plague'. The narrative is more compressed than in the other historians, and Theodoret often strings documents together, with only brief comments between. Original material of Antiochian information appears chiefly in the latter books. Theodoret's sources are in dispute. According to Valesius these were mainly Socrates and Sozomen; Albert Guldenpenning's thorough research placed Rufinus first, and next to him, Eusebius of Caesarea, Athanasius, Sozomen, Sabinus, Philostorgius, Gregory Nazianzen, and, least of all, Socrates. N. Glubokovskij counts Eusebius, Rufinus, Philostorgius, and, perhaps, Sabinus. The Religious History, with an appendix on divine love, contains the biographies of thirty (ten living) ascetics, held forth as religious models. It is a document of remarkable significance for understanding the
