Extant writings

Three surviving letters attributed to Arius are his letter to Alexander of Alexandria, his letter to Eusebius of Nicomedia, and his confession to Constantine. In addition, several letters addressed by others to Arius survive, together with brief quotations contained within the polemical works of his opponents. These quotations are often short and taken out of context, and it is difficult to tell how accurately they quote him or represent his true thinking.
