Book excerpt: This book discusses the occurrence of angelic imagery in early Christian discourse about the Holy Spirit. Taking as its entry-point Clement of Alexandria s less explored writings, Excerpta ex Theodoto, Eclogae propheticae, and Adumbrationes, it shows that Clement s angelomorphic pneumatology occurs in tandem with spirit christology, within a theological framework still characterized by a binitarian orientation. This complex theological articulation, supported by the exegesis of specific biblical passages (Zech 4: 10; Isa 11: 2-3; Matt 18:10), reworks Jewish and Christian traditions about the seven first-created angels, and constitutes a relatively widespread phenomenon in early Christianity. Evidence to support this claim is presented in the course of separate studies of Revelation, the Shepherd of Hermas, Justin Martyr, and Aphrahat.
