Constantine And Eusebius by Timothy D. Barnes

A rigorous study of the fourth century that traces the intertwined careers of the first Christian emperor and the bishop-historian who celebrated him, using close analysis of primary sources to reassess chronology and motive. It explores how imperial politics, church councils, and controversies—especially around Nicaea and so-called Arianism—shaped emerging orthodoxy and cemented the alliance between church and state. The book also highlights the propagandistic elements of contemporary narratives and shows how power and historiography together transformed Christianity from a persecuted movement into an imperial religion.
