The role of Pseudo-Dionysius in the consolidation of theosis is crucial, but it is by no means final. Nevertheless, after Pseudo-Dionysius, theosis experienced not only more systematic treatment as an independent subject of theological discourse, but it becomes one of the basic principles of Byzantine theology, and consequently of Eastern Orthodoxy.
The peculiar character of Dionysian theology could not be accurately appropriated without study of its relationship to later Neoplatonism. Therefore, significant attention in my book is given to the aspects of the influence this tradition had on Pseudo-Dionysius, in connection to the deification theme. Pseudo-Dionysian theology is justified neither as essentially “orthodox” Christian nor essentially “orthodox” Neoplatonic. Dionysius’ intricate synthesis of Christian and Neoplatonic elements, especially in his exposition of theosis, pays better justice to this anonymous author’s originality, and demonstrates the significance of his influence, both on the further development of Christian theology, and the advancement of Neoplatonic tradition.
The enigmatic nature of the Dionysian Corpus does not cease to puzzle scholars. Generally, Pseudo-Dionysius is approached from a solely Neoplatonic, or solely Christian, perspective. The outcome of this tendency obviously predetermines the treatment of his works, and in neither case pays proper justice to this body of literature. In my book, I attempt to research both lines of influence in the context of the overarching cultural background that was a significant aspect for the formation of a Christian imperial identity, and the development of Late Antiquity. This approach helps to situate and appropriate the Dionysian Corpus in a more accurate historical context, and to throw some additional light on the possible attribution of these works to Dionysius the Areopagite, not as a conscious forgery, but as a literary device, not an uncommon feature of the time.
Another recent book that mostly deals with Pseudo-Dionysius, but also touches on deification, is Divine Light: The Theology of Denys the Areopagite (2008) written by William Riordan. In Divine Light, the reader finds a friendly treatment of Dionysian theology presented in very accessible, but well researched and documented, form. The author attempts, and to some degree succeeds, to present this enigmatic corpus of Christian literature in its adequate historical and theological context. Treating the content of the corpus as unquestionably Christian and orthodox, Riordan clears, often without sufficient argumentation, Pseudo-Dionysius of all unfavorable charges.
Overall, the author presents a very attractive and innovative, although frequently speculative, synthesis of Dionysian theology, at times interpreting Dionysian theology in the context of its later appropriation in Christian tradition and contemporary scholarship. He even goes as far as trying to fill in gaps in Dionysian discourse; in other words, trying to state affirmatively what Pseudo-Dionysius might have been thinking, where the text of the corpus does not state it explicitly. His analysis of the relationship between Pseudo-Dionysius and Neoplatonic philosophy often betrays rather sketchy and limited, rather than comprehensive, engagement with Neoplatonic sources, and the tremendous complexities of this philosophical tradition in Late Antiquity and its impact on Pseudo-Dionysius.
The central role of theosis in Dionysian discourse is properly acknowledged, but its treatment is predominantly contextualized to the main exposition of Dionysian theology, rather than giving it a detailed and systematic assessment for its own sake. Riordan’s analysis of the Dionysian view of God, and God’s relation to the cosmos, as a sacred theatre of divinization, and his analysis of the human divinizing ascent of the soul, at times seems unintentionally slipping into the typically Neoplatonic form of paradoxical, but pantheistic, understanding of divine unity. Riordan’s handling of deification, as well as his general outlook on Dionysian theology, will be more reminiscent of the eclectic synthesis of the mystical spirituality of Plotinus, an understanding of the role of theurgy in Iamblichus, and the pantheistic metaphysical structure of Proclus than an accurate appropriation of this theme in the text of the Areopagitica.
The appendix to his book, on the treatment of rites of initiation in the work of Mircea Eliade, is remarkable in itself. It is probably the first precedent in Dionysian scholarship to draw a comparative analysis “between the Buryat shamanic initiation ceremony and the mystical initiation described by Denys.” Only one thing remains, what would the author of the Mystical Theology think about it?
Among other recent publications on theosis, I shall mention the thorough treatment of Thomas F. Torrance’s approach to deification in Myk Habet’s book, Theosis in the Theology of Thomas Torrance (2009); the published dissertation of William Schumacher, Who Do I Say That You Are? Anthropology and the Theology of Theosis in the Finnish School of Tuomo Mannermaa (2010); and Stephen Davis’s book, Coptic Christology in Practice: Incarnation and Divine Participation in Late Antique and Medieval Egypt (2008), that, through the narrative of Coptic Christology, extensively touches on the deification theme.
The last, but not the least, recent book on theosis I would like to discuss briefly in this introduction is Daniel Keating’s Deification and Grace (2007).18 Keating offers a very thoughtful and clear introduction to the basic aspects related to the deification theme/doctrine “as the full outworking of grace in the Christian life.”19 Starting his exposition with variations of the deification exchange formula and the language of deification, with its scriptural and christological significance in the history of Christian theology, Keating turns to the discussion of soteriological implications, where deification is closely linked to divine filiation and sanctification. The direct divine agency in the initiation of human deification as the “effective indwelling in us”20 and “participation in the divine life”21 is closely connected to the regenerating efficiency of the sacraments of baptism and the Eucharist. Continuous human progress in theosis that culminates in transformation into full maturity of Christ’s image, is intimately connected to divine indwelling, that both initiates divine filiation, and sustains human progress in the divine life of Christ. Such important traditional theological language that is closely affiliated with theosis, as “image” and “likeness,” “human perfection,” “virtue,” “participation,” sharing in Christ’s suffering, death, and resurrection, the role of prayer and asceticism, just to name a few, is adequately expounded in overarching biblical and christocentric perspectives. Keating’s book presents a good summary of theosis that in well-balanced and concise form outlines and explains the main elements intrinsically connected to the Christian understanding of human deification. I highly recommend this book for anyone who is interested in theosis.
With such ostensive number of publications on theosis that have sprung up in recent years, our current volume attempts not to summarize, or repeat, what has been already expounded on the subject, but to contribute to the ongoing interest in Christian understanding of deification. The complex terminological, experiential, speculative, mystical, soteriological, historical, and theological intensity that are inherently present in understanding the meaning of theosis in Christian theology, manifested themselves from the early patristic period, and never ceased to amaze and bewilder anyone who approached this theme.
This book is aimed at both those who are already students of theosis and those who are looking for an introductory text. For example, Ivan Popov’s essay on history of theosis in the early Eastern Church—virtually inaccessible before and known only to a very few experts—presents a valuable analysis of deification that is for the first time available in English. Other contributions to this volume cover subjects that in the opinions of their authors have not yet received sufficient attention, or were under-represented. They comprise both historical analyses and theological developments
