Saint Augustine, The City of God, Vol. II

Work out your own salvation with fear and trembling original: "Cum timore et tremore vestram ipsorum salutem operamini"; and: Do not be high-minded, but fear original: "Noli altum sapere, sed time"; and: But I fear, lest, as the serpent seduced Eve by his subtlety, so your minds also might be corrupted from the simplicity that is in Christ original: "Timeo autem, ne, sicut serpens Evam seduxit astutia sua, sic et vestrae mentes corrumpantur a castitate, quae est in Christo".
5 Concerning sadness, however, which Cicero calls aegritudo sickness of mind and Virgil calls dolor pain/grief—where he says, "They grieve and they rejoice" original: "Dolent gaudentque" (but I preferred to use the word "sadness" because "sickness" or "pain" is more commonly used for the body)—it is a more scrupulous question whether it can be found in a good person.

10 ### CHAPTER VIII.

For those things which the Greeks call eupatheias well-feelings, which Cicero called "constancies" original: "constantias" in Latin, the Stoics wished to be three, corresponding to the three perturbations of the soul of a wise man: will original: "voluntatem" in place of desire; joy original: "gaudium" in place of delight; caution original: "cautionem" in place of fear. But they denied that
20 there could be anything in the soul of a wise man corresponding to sickness or pain, which we preferred to call sadness to avoid ambiguity. For they say that the will seeks the good, which the wise man does; joy is from the good attained, which the wise man attains everywhere; caution avoids the evil, which the wise man ought to avoid. Furthermore, because sadness is from an evil that has already happened, and they believe no evil
25 can happen to a wise man, they said that nothing in his soul could correspond to it. Thus, they speak in such a way that they deny that anyone but the wise man can wish, rejoice, or be cautious; but they say that a fool can only desire, be delighted, fear, or be saddened. They hold that the former three are "constancies," while the latter four are "perturbations" according
30 to Cicero, or "passions" according to most others. In Greek, however, those three are called eupatheias well-feelings, as I said; but those four are called pathe passions. When I sought as diligently as I could whether this terminology agrees with the Holy Scriptures,
