Trinitarian Doctrine in Fortunatian of Aquileia’s Commentarii in evangelia

The purpose of this paper is to examine the Fortunatian’s Christology and Trinitarian theology that can be deduced from his recently found work Commentarii in evangelia and, by doing so, to present a general re-evaluation of his role in the political-doctrinal clashes at the middle of the 4th century. By investigating Fortunatian’s (Trinitarian) theology in relation to the prior early Latin Trinitarian doctrine and to different heterodox traditions, and ascertaining his doctrinal standpoint in the Arian controversy of the middle of the 4th century, his doctrine reveals itself to be far more Catholic and “pro-Nicene” – though remaining deeply rooted in the Latin theological tradition – that it was regarded before.
