Experience shows pagans capable of civil righteousness
Thesis V. Experience itself makes it plain that a man, even a pagan with no saving knowledge of God, can repay a deposit or a loan, care for his relatives, honour his parents, give alms to the poor, live temperately and soberly, and do many other such things.
In this way he can do many things that look fine and praiseworthy before men, who cannot see what lies within, and from them arises a kind of righteousness and civil uprightness. Such was found in Socrates, Epaminondas, Phocion, Scipio, Cato and many other men praised among the Gentiles, whose examples ought to make most Christians blush.

V. Et certe ipsa experientia planum est hominem etiam Ethnicum & nulla salutari Dei cognitione imbutum, posse depositum & mutuum reddere, cognatos colere, parentes honorare, Eleemosynam pauperibus largiri, temperanter & sobrie vivere, & plura ejusmodi: & sic multa facere apud homines, quos interiora latent, speciosa & laudabilia: & ex quibus exurgit justitia quaedam & honestas civilis: qualis fuit in Socrate, Epaminonda, Phocione, Scipione, Catone, & pluribus apud Gentiles laudatis viris, quorum exempla plerisque Christianis pudorem suffundere debent.
