The unreasoning repentance of those without God
Tertullian opens the treatise by describing how people who do not know God misuse repentance, applying it even to good deeds.
This kind of people—and we ourselves were once among them, blind, without the Lord's light—know repentance by nature only, as a certain passion of the soul that comes from the offense of a worse opinion. But they are as far from its reason as they are from the very author of reason. For reason is a thing of God, because God, the founder of all things, has provided, arranged, and ordered nothing without reason, and has willed nothing to be handled or understood without reason. Therefore whoever is ignorant of God must also be ignorant of God's things, because no treasure at all lies open to strangers. And so they cross the whole course of life without the helm of reason, and they do not know how to avoid the storm that hangs over the world.
How irrationally they wander in the act of repentance will be clear enough from this one point: they apply it even to their good deeds. They repent of faith, of love, of simplicity, of patience, of mercy, whenever anything has fallen into disfavor. They curse themselves because they have done good, and they fix in their hearts that kind of repentance especially which is inflicted on the best works, taking care to remember not to do anything good again. But they lie more lightly upon repentance for evils. In short, they sin more easily through the same repentance than they do right.
Latin
Paenitentiam hoc genus hominum, quod et ipsi retro fuimus, caeci, sine domini lumine, natura tenus norunt passionem animi quandam esse quae veniat de offensa sententiae peioris. Ceterum a ratione eius tantum absunt, quantum ab ipso rationis auctore. Quippe res dei ratio; quia deus omnium conditor, nihil non ratione providit, disposuit, ordinavit, nihil non ratione tractari intellegique voluit. Igitur ignorantes quique deum rem quoque eius ignorent necesse est, quia nullus omnino thesaurus extraneis patet. Itaque universam vitae conversationem sine gubernaculo rationis transfretantes imminentem saeculo procellam vitare non norunt. Quam autem in paenitentiae actu irrationabiliter diversentur, vel uno isto satis erit expedire, cum illam etiam in bonis factis suis adhibent. Paenitet fidei, amoris, simplicitatis, patientiae, misericordiae, prout quid in ingratiam cecidit. Semetipsos exsecrantur, quia benefecerint, eamque maxime paenitentiae speciem quae optimis operibus irrogatur in corde figunt, meminisse curantes, ne quid boni rursus praestent; contra paenitentiae malorum levius incubant. Denique facilius per eandem delinquunt quam per eandem recte faciunt.
