Farag persuasively demonstrates that three groups in late antiquity were concerned with these questions: Christian leaders, wealthy laypersons, and lawmakers. Conflicting answers usually coexisted, but from time to time they clashed and caused significant tension. In these disputes, juridical regulations and opinions mattered more than has been traditionally recognized. Considering familiar Christian controversies in novel ways, Farag's investigation shows that scholarship has misunderstood well-known religious figures by ignoring the legal issues they faced. This seminal text nuances vital aspects of scholarly conversations on sacred space, gift giving, wealth, and poverty in the late antique Mediterranean world, making use not only of Latin and Greek sources but also Coptic and Arabic evidence.
