In his commanding study Jesus der Christus im Glauben der Kirche, Alois Grillmeier observes that Chalcedon did more (‘am meisten angeregt hat’; vol. i [1990], 765) than any ancient council to inspire theological reflection. More recently, Richard Price and Michael Gaddis collected, edited, and translated the council's acta (Liverpool 2005), helping to bring to English scholars the workings and significance of Chalcedon. This present volume accordingly recognises the far-reaching importance of Chalcedon, a dozen essays signalling the impact that the council of ad 451 had on ecclesiastical identity and procedure. Thus contained here is Averil Cameron's fine introduction, followed by David Gwynn's analysis of the meaning of traditio christiana in late antiquity. How Chalcedon influenced later conciliar proceedings is examined in Thomas Graumann's look at Chalcedon's own understanding of the Council of Ephesus, and in Richard Price's breakdown of how Chalcedon affected Constantinople II (553); Catherine Cubitt next argues for Chalcedon's authority at the Lateran Council of 649, and Judith Herrin shows how Chalcedon was understood to have been ‘continued’ by the Quinisext Council of 692. Related essays include Fergus Millar on the Syriac Acts of the Latrocinium and Andrew Louth's answer to why the Syriac-speaking Church rejected Chalcedon. The other three essays include Price's synopsis – what he calls ‘narrative’ – of the council itself, Charlotte Roueché and her ‘Acclamations’ in which she shows how patterns of public acclamation during the council aided authenticating authority (both ecclesial as well as civil), while Michael Whitby rounds off these pages with a wonderful and welcome ‘An unholy crew? Bishops behaving badly at church councils’, an exploration into episcopal explosions. This volume is obviously for the specialist, yet a requirement for every library. With regard to thoroughness and overall attention, there is no equivalent to this collection available in English: each essay, followed by a comprehensive bibliography, offers yet one more illustration of how Chalcedon continues to speak to all of Christ's Church.
