The "Answers to the Orthodox" was re-edited in a different and more primitive form by Papadopoulos-Kerameus (St. Petersburg, 1895), from a Constantinople manuscript which ascribed the work to Theodoret. Though this ascription was adopted by the editor, it has not been generally accepted. Harnack has studied profoundly these four books and maintains, not without probability, that they are the work of Diodorus of Tarsus (Harnack, "Diodor von Tarsus., vier pseudojustinische Schriften als Eigentum Diodors nachgewiesen" in "Texte und Untersuch.", XII, 4, Leipzig, 1901).
