Activity and Participation in Late Antique and Early Christian Thought is an investigation into two basic concepts of ancient pagan and Christian thought. The study examines how activity in Christian thought is connected with the topic of participation: for the lower levels of being to participate in the higher means to receive the divine activity into their own ontological constitution. Torstein Theodor Tollefsen sets a detailed discussion of the work of church fathers Gregory of Nyssa, Dionysius the Areopagite, Maximus the Confessor, and Gregory Palamas in the context of earlier trends in Aristotelian and Neoplatonist philosophy. His concern is to highlight how the Church Fathers thought energeia (i.e. activity or energy) is manifested as divine activity in the eternal constitution of the Trinity, the creation of the cosmos, the Incarnation of Christ, and in salvation understood as deification.

Platonism and Christian Thought in Late Antiquity examines the various ways in which Christian intellectuals engaged with Platonism both as a pagan competitor and as a source of philosophical material useful to the Christian faith. The chapters are united in their goal to explore transformations that took place in the reception and interaction process between Platonism and Christianity in this period. The contributions in this volume explore the reception of Platonic material in Christian thought, showing that the transmission of cultural content is always mediated, and ought to be studied as a transformative process by way of selection and interpretation. Some chapters also deal with various aspects of the wider discussion on how Platonic, and Hellenic, philosophy and early Christian thought related to each other, examining the differences and common ground between these traditions. Platonism and Christian Thought in Late Antiquity offers an insightful and broad ranging study on the subject, which will be of interest to students of both philosophy and theology in the Late Antique period, as well as anyone working on the reception and history of Platonic thought, and the development of Christian thought.

St Theodore the Studite's Defence of the Icons provides an investigation of the icon-theology of St Theodore the Studite, mainly as it is presented in his three refutations of the iconoclasts, the Antirrhetici tres adversus iconomachos. Torstein Theodor Tollefsen explores Theodores 'philosophy of images', namely his doctrine of images and his arguments that justify the legitimacy of images in general and of Christ in particular. Tollefsen offers a historical, theological, and philosophical exploration of Theodore's doctrine of images and his arguments justifying the legitimacy of images and of Christ. In addition to the main elements of Theodores defence of the icon, like the Christological issue, the relation between image and prototype, the question of veneration, his explanation of why we may say of an image that 'this is Christ', and his innovative thinking on the representative character of the icon, the book has an introduction that places Theodore in the history of Byzantine philosophy: he has some knowledge of traditional logical topics and is able to utilize argumentative forms in countering his iconoclast opponents. The volume also provides an appendix which shows that the making of images is somehow natural given the character of Christianity as a religion.
