XIII. From this fountain original sin and its unhappy brood
XIII. From this fountain and Lerna of evils there flowed to Adams posterity, who descend from him according to the mode of nature, the universal fault of our nature, which is circumscribed by the name of original sin, with its whole and unhappy brood of sins and punishments, which — like the hydras heads — the new grace of the blessed seed at last cuts off savingly in those who receive this by living faith.
Of originating sin we saw in chapter 38; and of its brood in what follows. In its compass theologians chiefly understand three things: first, the guilt of both deaths, which passes to posterity by a triple way — namely (i) by participation of fault, because all posterity were in Adam by seminal reason, as in a head or root, fountain and common principle of the whole nature; (ii) by imputation, because Adam so stood in grace that if he sinned the whole posterity with him would fall from it; (iii) by natural propagation, because through the parents generation we share the condition of the guilty; second, the privation of divine grace and the defect or lack of wisdom, righteousness, and holiness; third, a horrible darkness in the mind, and in the will, affections, and so the whole human a proneness and crookedness toward sinning.
Book III COMPLETE. Book IV begins at physical page 1005 On the principles and means of human salvation; Chapter 1 On the grace of paternal compassion.

XIII. Ex hoc fonte et lerna malorum ad posteros Adae, qui secundum naturae modum ab eo descendunt, profluxit universale naturae nostrae vitium, quod nomine peccati originalis circumscribitur, cum omnimoda sua et infelici peccatorum poenarumque sobole, quam, veluti hydrae capita, nova gratia seminis benedicti in iis qui hoc fide viva recipiunt tandem salutariter praecidit. De peccato originis vidimus cap. 38; deque illius prole in sequentibus. Eius vero complexu Theologi tria potissimum intelligunt: 1. reatum utriusque mortis, qui in posteros transit triplici via, nempe (i) participatione culpae, quia omnes posteri in Adamo fuerunt seminali ratione, tanquam in capite seu radice, fonte ac communi principio totius naturae; (ii) imputatione, quia Adamus ita stabat in gratia ut, si peccaret, tota cum eo posteritas ea excideret; (iii) naturali propagatione, quia per generationem parentis rei conditionem participamus; 2. privationem divinae gratiae et defectum seu carentiam sapientiae, iustitiae et sanctimoniae; 3. horrendam in mente caliginem, in voluntate, affectibus totoque adeo homine ad peccandum pronitatem ac pravitatem.
