This collection of essays has its origin in a conference held at Oxford in 2006 to mark the publication of the first English edition of the Acts of Chalcedon. Its aim is to place Chalcedon in a broader context, and bring out the importance of the acts of the early general councils from the fifth to the seventh century, documents that because of their bulk and relative inaccessibility have received only limited attention till recently. This volume is evidence that this situation is now rapidly changing, as historians of late antiquity as well as specialists in the history of the Christian Church discover the richness of this material for the exploration of common concerns and tensions across the provinces of the Later Roman Empire, language use, networks of influence and cultural exchange, and political manipulation at many different levels of society. The extent to which the acts were instruments of propaganda and should not be read as a pure verbatim record of proceedings is brought out in a number of the essays, which illustrate the fascinating literary problems raised by these texts.

In Das Konzil von Chalcedon und die Kirche Sandra Leuenberger-Wenger offers a new perspective on the council of Chalcedon, analyzing the rich material of its acts. Leuenberger-Wenger shows the entanglement of the Christological debate with other fields of conflict concerning the status and authority of different episcopal sees and of monasticism in the church. The study emphasizes the importance of the traditionally neglected second part of the council with its canons and resolutions and argues that these regulations had a deep impact on the structures of the church as well as on the reception of the council and its definition of faith. The evaluation of a wide range of sources places the refusal of the definition of faith in the broader context of the transformation processes of the Roman Empire in Late Antiquity and the rejection of an increasingly institutionalized Byzantine Church. In Das Konzil von Chalcedon und die Kirche entwirft Sandra Leuenberger-Wenger anhand der Konzilsakten ein neues Bild von der Bedeutung dieses Konzils für die Kirche. Sie zeigt die Verknüpfung des christologischen Streits mit weiteren kirchlichen Konfliktfeldern wie dem Status und der Autorität einzelner Bischofssitze und des Mönchtums. Die Untersuchung betont die Bedeutung des zweiten Konzilsteils für die Entwicklung der Kirche und macht deutlich, wie die Regulierungen auf kirchenpolitischer und struktureller Ebene die Rezeption des Konzils entscheidend mitbestimmten. Die Auswertung eines breiten Quellenmaterials verortet das Konzil und seine schwierige Rezeption in den spätantiken Transformationsprozessen des Römischen Reichs im Übergang zum Mittelalter und deutet die Konflikte um die Glaubensdefinition im Horizont der umfassenderen Ablehnung einer zunehmend institutionalisierten byzantinischen Reichskirche.

In 451 CE the Council of Chalcedon was called to assert the preeminence of orthodox Catholic doctrine against the heresy of men who refused what we now refer to as the Definition of Faith, or the belief in Jesus Christ as both man and divine spirit during his lifetime. This book is suitable for scholars studying this period.

Theodoret of Cyrus (c.393-c.466) was the most able Antiochene theologian in the defence of Nestorius from the Council of Ephesus in 431 to the Council of Chalcedon in 451. While the works of Theodore of Mopsuestia and Nestorius are extant today only in translations or in fragments, Theodoret's voluminous works are largely available in their original Greek. This study of his writings throws considerable light on the theology of those councils and the final evolution and content of Antiochene Christology. Clayton demonstrates that Antiochene Christology was rooted in the concern to maintain the impassibility of God the Word and is consequently a two-subject Christology. Its fundamental philosophical assumptions about the natures of God and humanity compelled the Antiochenes to assert that there are two subjects in the Incarnation: the Word himself and a distinct human personality. This Christology is not the hypostatic union of the Councils of Ephesus and Chalcedon.
