This book contends that ancient racial ideologies--encompassing prevailing beliefs, attitudes, and practices regarding race--provide valuable insights into the Gospel of John's portrayal of the Holy Spirit. It examines the racial rhetoric surrounding lineages, racial violence, cross-cultural encounters, and the formation of a new familial identity, all interpreted through the lens of the Holy Spirit. By engaging with the Gospel's treatment of the Holy Spirit in light of these racial dynamics, the study offers a more nuanced understanding of how conceptions of race intersect with the emerging theology of the Holy Spirit within the Johannine community.
