25 And lest any one should suppose that we, through distrust in our reply, invest the gods with the gifts of serenity, that we assign to them minds free from resentment, and far removed from all excitement, let us allow, since it is pleasing to you, that they put forth their passion upon us, that they thirst for our blood, and that now for a long time they are eager to remove us from the generations of men. But if it is not troublesome to you, if it is not offensive, if it is a matter of common duty to discuss the points of this argument not on grounds of partiality, but on those of truth, we demand to hear from you what is the explanation of this, what the cause, why, on the one hand, the gods exercise cruelty on us alone, and why, on the other, men barn against us with exasperation.
You follow, our opponents say, profane religious systems, and you practise rites unheard of throughout the entire world. What do you, O men, endowed with reason, dare to assert? What do you dare to prate of? What do you try to bring forward in the recklessness of unguarded speech? To adore God as the highest existence, as the Lord of all things that be, as occupying the highest place among all exalted ones, to pray to Him with respectful submission in our distresses, to cling to Him with all our senses, so to speak, to love Him, to look up to Him with faith—is this an execrable and unhallowed religion, full of impiety and of sacrilege, polluting by the superstition of its own novelty ceremonies instituted of old?
