Abstract
Basil of Caesarea’s homily On Not Three Gods (CPG 2914) has been neglected by scholars because of lingering questions over its authenticity, integrity, and interpretation. Complicating these difficulties are the verbatim parallels which this homily exhibits with other non-Basilian texts. This study proposes solutions to these problems and its most thorny interpretative issues. The authenticity of the questionable part of the homily is demostrated by adducing parallels from Basil’s indisputably authentic works. The integrity and overall logic of the homily becomes clear once it is understood that Basil’s tactic for refuting the Pneumatomachian charge of tritheism was to defend his theology along anti-Heteroousian lines. The homily only seems to lack integrity because Basil has not integrated his sources as seamlessly as he could have. Thus On Not Three Gods should no longer be ignored by scholars seeking to understand Basil’s Trinitarian thought and ecclesiastical debates.
