Most treatments of early Christian notions of purity privilege a spiritualized version of the concept. Purity, Community, and Ritual in Early Christian Literature challenges this over-generalization to demonstrate "that purity was open for negotiation" through methodically analyzing a vast corpus of securely-provenanced second- and third-century Greek, Syriac, and Coptic Christian texts, both canonical and non-canonical (5). Blidstein has written the most comprehensive treatment of Christian attitudes toward purity and defilement to date. Drawing on recent methodologies that understand defilement as "a biological reaction of disgust towards certain actions and substances" (7), the author employs a "heuristic consisting of 'battle' and 'truce'" to explain how early Christian purity discourse functioned (11). The truce perception portrayed purity and impurity as statuses in order to define "the borders of social groups, spaces, and times" (11). The more prevalent battle perception, by contrast, conceived of purity and impurity as competing moral forces, often aligned with other opposing pairs like "holiness and unholiness, saint and demon, righteousness and sin, flesh and spirit, out-group and in-group" (11). After providing a cursory overview of the historical context for purity discourses in the Greco-Roman East and Judaism in Part I, Blidstein devotes each chapter to various ritual practices which are grouped both chronologically and according to their continuity or discontinuity with prevailing Jewish and Greco-Roman concepts. Thus, diet and death constitute "Part II: Breaking with the Past," while baptism, eucharist, and sexual relations form "Part III: Roots of a New Paradigm: The First Two Centuries." "Part IV: New Configurations: Purity, Body, and Community in the Third Century" examines Christian traditions inconsistent with the trajectories delineated in previous chapters, Jewish-Christian communities, and Origen. In Part II, Blidstein argues that early Christian writers construed dietary- and death-related purity regulations as irrelevant, i.e., annulled by Jesus, in order "to differentiate Christian from Jewish" customs. By detaching the practices' ritual elements from their moral dimension, Christian eating customs, and to a lesser [End Page 133] extent burial rites, were constructed "as representing internal purity, powered by human agency and linked to questions of good and evil" (90). This battle perspective emerged as a chief weapon of anti-Jewish polemics. Other examples of the growing battle perspective appear in Part III. Blidstein demonstrates how baptism, construed as forgiveness of sins, "became a major site for addressing . . . the relationship between ritual and moral purity, between external action and the inner disposition" (131). Attitudes toward sexual purity, on the other hand, exhibit both battle and truce perspectives. Entailing both body and soul, sexual impurity extended beyond illicit sexual activity, as understood in both Jewish and Greco-Roman culture, to include "sexual contact as a whole, even inside 'legitimate' marriage . . . toward the de-legitimization of sexuality" (180). Thus, Blidstein concludes that the moral dimension of sexuality constituted a battle perspective, while the physical dimension constituted a truce perspective. Unlike the first two Christian centuries of baptismal and sexual discourse, in eucharistic theology, purity was understood as a prerequisite for participation rather than its result (148). Not until the third century is the eucharist understood as purificatory. Part IV examines baptism, sexual purity, and diet in what Blidstein terms "Jewish-Christian writings": Pseudo-Clementine literature, the Didascalia Apostolorum, the Cologne Mani Codex, and the Protoevangelium of James. This section also contains an extensive discussion of menstrual impurity in the Pseudo-Clementines. As in some rabbinic circles, menstrual impurity and male genital emissions are connected to demons, menstrual blood and emissions are polluting, and washing rituals serve purificatory roles on both the moral and physical levels (190–91, 196). In the Didascalia Apostolorum, by contrast, menstruation does not require purification because the Holy Spirit has entered a woman's body during baptism and driven out her demons once and for all (195). Blidstein concludes that water purification, including baptism, exhibits continuity with Jewish notions of purification due to the broader context of demonology. Blidstein concludes...
