This volume is a meticulously researched text on pneumatology which puts the major pneumatological issues together without con ning to the traditional way of dealing with the doctrine of the Holy Spirit. Although pneumatology has been a neglected eld in theological discussions of the past, there is a renewal of interest among theologians on pneumatology today. This renewal of interest has led to the formation of this work on the role of the Holy Spirit in the Protestant Systematic Theology. Through highlighting the role and signi cance of the Holy Spirit in the whole divine action, this volume contends that pneumatology is not a dull theological locus, but rather an essential theological disposition relevant for today. The detailed arguments found within challenge and inspire the contemporary pneumatological discussions as it relates to all the facets of theological re ection and action.
