Students of the doctrinal controversies of the fifth century and beyond will welcome Pásztori-Kupán's translation and introduction to Theodoret of Cyrus. Selected for translation are several complete works that have never before appeared in English (On the holy and vivifying Trinity and On the inhumanation of the lord). The book also contains selections from other important texts of Theodoret not readily available to English readers. The translations are readable and competent. Pásztori-Kupán opts to retain some technical vocabulary in Greek, or close to the Greek, better to present the theological issues. Thus, oikonomia is untranslated and enanthropesis is rendered inhumanation. In general, this is a good strategy that adds to the text's comprehensibility. The volume suffers from two weaknesses, however. First, the introduction presents a very traditional view of Theodoret as a participant in the ‘Antiochene school’. Grillmeier's ‘logos-sarx/logos-anthropos’ typology figures prominently, as does a fairly defensive attitude toward Nestorius and his legacy. The introduction does not address some of the significant scholarship that has been critical of that typology and more sympathetic to the general outcomes of the councils of Ephesus and Chalcedon. Pásztori-Kupán need not agree with the conclusions of these other voices, but they ought to be present in the introductory discussion. Second, the introduction fails to give sufficient attention to Theodoret the biblical interpreter. From this introduction one has the impression that Theodoret was a doctrinal theologian. He was not. Some larger discussion of the current debate about how ancient interpretive methods and arguments about the meaning of the Bible determined theological conclusions would have made the introduction stronger. Despite such shortcomings, these translations are a valuable contribution to The Early Church Fathers series.
