“Heaven and Hell suppose two distinct species of men, the good and the bad; but the greatest part of mankind float betwixt vice and virtue.”

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.
The City of God (early 400s)
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.

Jane Eyre (1847)
Context: p>Conventionality is not morality. Self-righteousness is not religion. To attack the first is not to assail the last. To pluck the mask from the face of the Pharisee, is not to lift an impious hand to the Crown of Thorns. These things and deeds are diametrically opposed: they are as distinct as is vice from virtue. Men too often confound them: they should not be confounded: appearance should not be mistaken for truth; narrow human doctrines, that only tend to elate and magnify a few, should not be substituted for the world-redeeming creed of Christ. There is — I repeat it — a difference; and it is a good, and not a bad action to mark broadly and clearly the line of separation between them.The world may not like to see these ideas dissevered, for it has been accustomed to blend them; finding it convenient to make external show pass for sterling worth — to let white-washed walls vouch for clean shrines. It may hate him who dares to scrutinise and expose — to rase the gilding, and show base metal under it — to penetrate the sepulchre, and reveal charnel relics: but hate as it will, it is indebted to him.</p

Context: A thing, moderately good, is not so good as it ought to be. Moderation in temper, is always a virtue; but moderation in principle, is a species of vice.
