This ecclesiological study argues that Reformed ecclesiology cannot be separated from Reformed Christology. The christological foundation of Reformed doctrine of the church will be examined as Reformed theology portrays the important ecclesiological topics in the light of its christological thoughts. This book offers potential for the future of the church with her pastoral concern. It will serve as a stimulus against the erroneous paths of ecclesiocentrism on the one hand and church-forgetfulness on the other. Even though the chapters of the book deal with classical topics in ecclesiology, the work will try to analyze and answer contemporary challenges the church faces. This book is not a systematic treatment in the sense of an examination of the whole developed in terms of one principle (that is, Christology). Rather, the concern of this book is to expound the Holy Scripture realistically and to engage with the contemporary church in her concrete existence. The study will weave together insights from biblical, historical, confessional, philosophical, and contemporary studies in a fruitful way.
