T&T Clark Handbook of Pneumatology [PDF ebook] 

This handbook provides an interdisciplinary and diverse reference work to the Holy Spirit. Daniel Castelo and Kenneth M. Loyer gathered together a wide range of voices that are religiously, geographically, and ethnically diverse, bringing theology into conversation with biblical studies, ethics and morality, and global Christian studies.
The
T&T Clark Handbook of Pneumatology examines the Holy Spirit in a variety of sources, such as the Synoptic Gospels, the Catholic Epistles, the Old Testament, and the Hebrew Scriptures. It also includes chapters on key concepts in the field, such as mediation and sacramentality, ecology, and creation. This broad scope enables readers to appreciate how nuanced the field of Pneumatology is, and how it can be relevant for other Christian discourses.
