Lossky's great work on Eastern Orthodoxy covers the whole range of its spirituality and theology. Combining careful theology with the warmth of the deep personal devotion of the author, 'The Mystical Theology of the Eastern Church' is the best introduction to Orthodox teaching and theology available. It provides a reliable and informative presentation of the theological spirit of the Eastern Church. His account makes clear the profound theological differences underlying the practices of the East and West, and yet it is also an important contribution to ecumenism and to the life of Christian devotion. It brings together subjects that are more usually separated, asserting that there is no true mysticism that is not firmly rooted in theology, and no true theology that is not experienced, and therefore mystical. The tradition of the Eastern Church is presented as a mystical theology with doctrine and experience mutually conditioning each other.

Origins of Eastern Christian Mysticism asserts that the thinkers between Basil of Caesarea and Symeon the New Theologian were important mainly for their role in the formation of Hesychasm, a fourteenth-century mystical movement in the Eastern church. The book surveys previous research on Proto-Hesychasm and sets forth eight Hesychastic trends in its practitioners: monasticism, dark and light mysticism, and an emphasis on the heart, theōsis, the humanity of Christ, penthos, and unceasing prayer. Theodore Sabo integrates detailed and carefully researched accounts of the lives and thought of the foundational figures of Hesychasm into a compelling narrative of the movement's origins. The Cappadocian fathers established monasticism as the predominant milieu of Proto-Hesychasm and emphasized both theōsis and dark mysticism. Dark mysticism would come into conflict with the light mysticism of their contemporary Pseudo-Macarius, but both currents would be passed on to the Hesychasts. Macarius was a seminal figure within Proto-Hesychasm, responsible for its stress on light mysticism and heart mysticism. Hesychasm itself, the author contends, emerged from two main Proto-Hesychast fonts, the philosophical (represented by such figures as Pseudo-Dionysius and Maximus the Confessor) and the ascetic (the realm of figures like John Climacus and Isaac of Nineveh). The former school transmitted to Hesychasm a virtually unacknowledged Platonism; the latter contributed to Hesychasm's preoccupation with theōsis, penthos, and unceasing prayer, albeit from a solely monastic perspective. Finally, Symeon the New Theologian emerged as the redoubtable successor to these schools, unifying their distinct traditions in his philosophical approach. While previous scholarship has documented the connections between Proto-Hesychasm and Hesychasm, Origins of Eastern Christian Mysticism is unique in its treatment of the Proto-Hesychasts as a distinguishable group, and as direct instigators of Hesychasm. This provocative study should be of interest to students and scholars of the late antique history of the Eastern Orthodox Church, as well as to contemporary theologians steeped in the Eastern mystical tradition.

Orthodox Christian theology is often presented as the direct inheritor of the doctrine and tradition of the early Church. But continuity with the past is only part of the truth; it would be false to conclude that the eastern section of the Christian Church is in any way static. Orthodoxy, building on its patristic foundations, has blossomed in the modern period. This volume focuses on the way Orthodox theological tradition is understood and lived today. It explores the Orthodox understanding of what theology is: an expression of the Church's life of prayer, both corporate and personal, from which it can never be separated. Besides discussing aspects of doctrine, the book portrays the main figures, themes and developments that have shaped Orthodox thought. There is particular focus on the Russian and Greek traditions, as well as the dynamic but less well-known Antiochian tradition and the Orthodox presence in the West.

Theosis, or the principle of divine-human communion, sparks the theological imagination of Orthodox Christians and has been historically important to questions of political theology. In The Mystical as Political: Democracy and Non-Radical Orthodoxy, Aristotle Papanikolaou argues that a political theology grounded in the principle of divine-human communion must be one that unequivocally endorses a political community that is democratic in a way that structures itself around the modern liberal principles of freedom of religion, the protection of human rights, and church-state separation. Papanikolaou hopes to forge a non-radical Orthodox political theology that extends beyond a reflexive opposition to the West and a nostalgic return to a Byzantine-like unified political-religious culture. His exploration is prompted by two trends: the fall of communism in traditionally Orthodox countries has revealed an unpreparedness on the part of Orthodox Christianity to address the question of political theology in a way that is consistent with its core axiom of theosis; and recent Christian political theology, some of it evoking the notion of “deification,” has been critical of liberal democracy, implying a mutual incompatibility between a Christian worldview and that of modern liberal democracy. The first comprehensive treatment from an Orthodox theological perspective of the issue of the compatibility between Orthodoxy and liberal democracy, Papanikolaou’s is an affirmation that Orthodox support for liberal forms of democracy is justified within the framework of Orthodox understandings of God and the human person. His overtly theological approach shows that the basic principles of liberal democracy are not tied exclusively to the language and categories of Enlightenment philosophy and, so, are not inherently secular.

The scholarly contributions gathered together in this volume discuss themes related to the cultural, social and ethical dimension of St Gregory Palamas’ works. They relate his mystical philosophy and theology to contemporary debates in metaphysics, philosophy of language, ethics, philosophy of culture, political philosophy, epistemology, and philosophy of religion and theology, among others. The book considers a variety of topics of special interest to Christian theologians, philosophers and art historians including church and state relations, similarities and differences between Palamas, contemporary phenomenologists and philosophers of language, and hesychast influences on late Byzantine iconography.
