The New Testament finds many ways to depict the relationship of Christians to Jesus. They are his disciples, sons, daughters, friends. But it is perhaps too little recognized that they are also his slaves. This study sets out to uncover what it means to be a “slave of Christ.” Harris begins by assessing the nature of actual slavery in the Graeco‑Roman world and the New Testament’s attitude toward it, drawing insights from this background to unfold the metaphor of slavery to Christ. Topics include slavery and spiritual freedom, lordship, ownership, and privilege.
