On the Diversity and Influence of the Eusebian Alliance: The Case of Theodore of Heraclea

Abstract

This article offers, for the first time in English, a reconstruction of the career of Theodore of Heraclea, a leading figure in the Eusebian alliance from the early 330s until the mid-350s. It also provides an overview of Theodore's literary remains and suggests that the anti-Marcellan tone of his surviving fragments is in keeping with the other documents that emanated from the Eusebian alliance during this period, especially those from the Council of Serdica (343) and the Council of Sirmium (351). Finally, it is suggested that the diversity of ways in which Theodore was received by later patristic authors illustrates that the polarising categories of ‘Arian’ and ‘Nicene’ are insufficiently nuanced to describe Theodore's actual theological concerns.
