‘The book presents itself as a working tool rather than a claim for a particular reconstruction. In keeping with the spirit of the series “Translated Texts for Historians”, its aim is to provide readers with the essential information needed to understand these crucial documents in their own right. Rather than guiding the reader toward a given conclusion, it lays out the historical, literary, and theological groundwork that leaves room for the reader’s own interpretation.’ Samuel Fernández, Plekos
