Constantine's life – his career, faith and relationship to the church – raises questions for Christians and for historians that cannot be ignored. Scholars continue to be intrigued with Constantine the man, the influence he wielded over the church and the paradigm that he introduced for church-state relations. Seventeen hundred years after Constantine's victory at Milvian Bridge, Rethinking Constantine reinvigorates the conversation and examines the historical sources that inform our picture of Constantine, the theological developments that occurred in the wake of his rise to power and the aspects of Constantine's legacy that have shaped church history. Rethinking Constantine reassesses our picture of Constantine through careful historical enquiry within the scope of the early Christian period.
