This article focuses on the doctrine of divine favour and instrumentality as viewed from the emperor's own perspective, in relation to the early development of the ‘Arian controversy’ as far as the Council of Nicaea. While modern writers have focused on explicit statements by Constantine to suggest that unity was the emperor's highest priority, this article reveals a pattern by which he sought to manage divine favour and argues that doing so effectively was of primary importance to him. Such a shift in understanding the emperor's priorities adds to the range of explanations for his later apparent inconsistencies as the actual achievement of unity continually eluded him.
