Abstract
This article explores the ecclesiological views of Dionysius the Areopagite through the examination of his Ecclesiastical Hierarchy, where he discusses the hierarchical ranks and sacraments, and of his Letter VIII to monk Demophilus, which is important for Dionysius's understanding of hierarchical organisation and discipline. These issues are put in the context of other important questions of the Areopagite's thought, such as his symbolic theory, the character of deification and the role of knowledge in it. Although the Areopagite is one of the most famous among early Christian Greek thinkers, his ecclesiology is somewhat less familiar, especially in the West. This article tries to fill in that gap, hence it represents a general, introductory outline of Dionysius's ecclesiology, with the aim of making it more accessible to the broader Western readership and to incite further research on the subject.
