“Wherefore, though good and bad men suffer alike, we must not suppose that there is no difference between the men themselves, because there is no difference in what they both suffer. For even in the likeness of the sufferings, there remains an unlikeness in the sufferers; and though exposed to the same anguish, virtue and vice are not the same thing.”

Variant translations:
Virtue and vice are not the same, even if they undergo the same torment.
The violence which assails good men to test them, to cleanse and purify them, effects in the wicked their condemnation, ruin, and annihilation.

Context: Wherefore, though good and bad men suffer alike, we must not suppose that there is no difference between the men themselves, because there is no difference in what they both suffer. For even in the likeness of the sufferings, there remains an unlikeness in the sufferers; and though exposed to the same anguish, virtue and vice are not the same thing. For as the same fire causes gold to glow brightly, and chaff to smoke; and under the same flail the straw is beaten small, while the grain is cleansed; and as the lees are not mixed with the oil, though squeezed out of the vat by the same pressure, so the same violence of affliction proves, purges, clarifies the good, but damns, ruins, exterminates the wicked. And thus it is that in the same affliction the wicked detest God and blaspheme, while the good pray and praise. So material a difference does it make, not what ills are suffered, but what kind of man suffers them. For, stirred up with the same movement, mud exhales a horrible stench, and ointment emits a fragrant odor.

Context: He could not think of the animals without shuddering in anguish. He looked into the eyes of the beasts and saw there a soul like his own, a soul which could not speak; but the eyes cried for it: "What have I done to you? Why do you hurt me?" He could not bear to see the most ordinary sights that he had seen hundreds of times—a calf crying in a wicker pen, with its big, protruding eyes, with their bluish whites and pink lids, and white lashes, its curly white tufts on its forehead, its purple snout, its knock-kneed legs:—a lamb being carried by a peasant with its four legs tied together, hanging head down, trying to hold its head up, moaning like a child, bleating and lolling its gray tongue:—fowls huddled together in a basket:—the distant squeals of a pig being bled to death:—a fish being cleaned on the kitchen-table.... The nameless tortures which men inflict on such innocent creatures made his heart ache. Grant animals a ray of reason, imagine what a frightful nightmare the world is to them: a dream of cold-blooded men, blind and deaf, cutting their throats, slitting them open, gutting them, cutting them into pieces, cooking them alive, sometimes laughing at them and their contortions as they writhe in agony. Is there anything more atrocious among the cannibals of Africa? To a man whose mind is free there is something even more intolerable in the sufferings of animals than in the sufferings of men. For with the latter it is at least admitted that suffering is evil and that the man who causes it is a criminal. But thousands of animals are uselessly butchered every day without a shadow of remorse. If any man were to refer to it, he would be thought ridiculous.—And that is the unpardonable crime. That alone is the justification of all that men may suffer.

Context: Jesus Christ has to suffer and be rejected. … Suffering and being rejected are not the same. Even in his suffering Jesus could have been the celebrated Christ. Indeed, the entire compassion and admiration of the world could focus on the suffering. Looked upon as something tragic, the suffering could in itself convey its own value, its own honor and dignity. But Jesus is the Christ who was rejected in his suffering. Rejection removed all dignity and honor from his suffering. It had to be dishonorable suffering. Suffering and rejection express in summary form the cross of Jesus. Death on the cross means to suffer and to die as one rejected and cast out. It was by divine necessity that Jesus had to suffer and be rejected. Any attempt to hinder what is necessary is satanic. Even, or especially, if such an attempt comes from the circle of disciples, because it intends to prevent Christ from being Christ. The fact that it is Peter, the rock of the church, who makes himself guilty doing this just after he has confessed Jesus to be the Christ and has been commissioned by Christ, shows that from its very beginning the church has taken offense at the suffering of Christ. It does not want that kind of Lord, and as Christ's church it does not want to be forced to accept the law of suffering from its Lord.
