[Sidenote: Political meaning of his exile.]
The exile governed Egypt from his hiding in the desert. Alexandria was searched in vain; in vain the malice of Constantius pursued him to the court of Ethiopia. Letter after letter issued from his inaccessible retreat to keep alive the indignation of the faithful, and invisible hands conveyed them to the farthest corners of the land. Constantius had his revenge, but it shook the Empire to its base. It was the first time since the fall of Israel that a nation had defied the Empire in the name of God. It was a national rising, none the less real for not breaking out in formal war. This time Greeks and Copts were united in defence of the Nicene faith, so that the contest was at an end when the Empire gave up Arianism. But the next breach was never healed. Monophysite Egypt was a dead limb of the Empire, and the Roman power beyond Mount Taurus fell before the Saracens because the provincials would not lift a hand to fight for the heretics of Chalcedon.
The victory seemed won when the last great enemy was driven into the desert, and the intriguers hasted to the spoil. They forgot that the West was only overawed for the moment, that Egypt was devoted to its patriarch, that there was a strong opposition in the East, and that the conservatives, who had won the battle for them, were not likely to take up Arianism at the bidding of their unworthy leaders. Amongst the few prominent Eusebians of the West were two disciples of Arius who held the neighbouring bishoprics of Mursa and Singidunum, the modern Belgrade. Valens and Ursacius were young men in 335, but old enough to take a part in the infamous Egyptian commission of the council of Tyre. Since that time they had been well to the front in the Eusebian plots. In 347, however, they had found it prudent to make their peace with Julius of Rome by confessing the falsehood of their charges against Athanasius. Of late they had been active on the winning side, and enjoyed much influence with Constantius. Thinking it now safe to declare more openly for Arianism, they called a few bishops to Sirmium in the summer of 357, and issued a manifesto of their belief for the time being, to the following general effect. 'We acknowledge one God the Father, also His only Son, Jesus Christ our Lord. But two Gods must not be preached. The Father is without beginning, invisible, and in every respect greater than the Son, who is subject to Him together with the creatures. The Son is born of the Father, God of God, by an inscrutable generation, and took flesh or body, that is, man, through which he suffered. The words _essence_, _of the same essence_, _of like essence_, ought not to be used, because they are not found in Scripture, and because the divine generation is beyond our understanding.' Here is something to notice besides the repeated hints that the Son is no better than a creature. It was a new policy to make the mystery in the manner of the divine generation an excuse for ignoring the fact. In this case the plea of ignorance is simply impertinent.
