The doctrine of the Trinity has been central to Christian faith since the fourth century, but it is often the cause of more confusion than understanding. The author here overcomes this by looking at it from the point of view of one who vehemently rejected it. Eunomius of Cyzicus was condemned as a heretic during his lifetime in the fourth century and after. Richard Paul Vaggione uses Eunomius' life to examine how the whole Christian community, including ordinary men and women, helped determine how this often abused doctrine was - and is - understood.

The 4th-century writer, Eunomius of Cyzicus, is virtually the only Arian theologian whose dogmatic works have survived to any significant degree. As an important representative of Arianism, he has provided unique insight into the world of Arius's followers, recognizing their continuation of his work and their criticism of it. The most complete edition of Eunomius's works yet published, this unique work contains both the actual text of, and the means of access to, all of Eunomius's surviving works and fragments. With new translations by the editor, this definitive collection offers a readable text that casts new light on the meaning and significance of Arianism.
