10 But, says he, let the altars be restored to the images, and their ornaments to the shrines. Let this demand be made of one who shares in their superstitions; a Christian Emperor has learned to honour the altar of Christ alone. Why do they exact of pious hands and faithful lips the ministry to their sacrilege? Let the voice of our Emperor utter the Name of Christ alone, and speak of Him only, Whom he is conscious of, for, “the King's heart is in the hand of the Lord.” Has any heathen Emperor raised an altar to Christ? While they demand the restoration of things which have been, by their own example they show us how great reverence Christian Emperors ought to pay to the religion which they follow, since heathen ones offered all to their superstitions.
11 a. We began long since, and now they follow those whom they excluded. We glory in yielding our blood, an expense moves them. We consider these things in the place of victories, they think them loss. Never did they confer on us a greater benefit than when they ordered Christians to be beaten and proscribed and slain. Religion made a reward of that which unbelief thought to be a punishment. See their greatness of soul! We have increased through loss, through want, through punishment; they do not believe that their rites can continue without contributions.
