The greatest website on the Internet went down, fourthcentury.com. Because of this, I will post what I can find, as part of my own Fourth Century Collection – and pray that it comes back up.

CPG 2046Incipit Καλῶς φρονῶν εὔχου πάντας Date c. 318 Ancient source Athanasius, On the Synods 17 Modern edition used H-G. Opitz, Athanasius Werke, band 2 (Berlin: De Gruyter, 1940). And Eusebius of Nicomedia in addition wrote thus to Arius:
Since you think properly, pray that everyone will think that way. For it is clear to all that the thing which is made did not exist before it came into being; but rather what came into being has a beginning to its existence.

Eusebius of Nicomedia was exiled after Nicaea by the Emperor for not condemning Arius. He spent only a few years in exile, and was brought back to his see, perhaps due to the Arian influence by family members of the Emperor. It was this Eusebius which baptized Constantine upon his death bed.
It should be reminded that the Church Historian, Eusebius of Caesarea was himself a support of Arius.
