Cap. VIII Arg.: peccata reprobi sunt causa omnium effectorum — therefore also of reprobation
Argument: the sins of the reprobate are the cause of all the effects of reprobation itself; therefore also of divine reprobation as it regards those effects. As to the first effect — hardening or subtraction of peculiar grace — it plainly arises from demerits of antecedent sins (Rom. 1; 2 Thess. 2; Exod. 9). As to the last — eternal damnation — human demerits are plainly its cause from the very form of the sentence passed at the final judgment.
Latin
Peccata reprobi sunt causa omnium effectorum reprobationis ipsius: Ergo etiam reprobationis Divinae, ut respicit illos effectus. Quod enim attinet ad primum effectum, scilicet indurationem seu subtractionem peculiaris gratiae, patet illam ex peccatorum antecedentium demeritis oriri: Rom. i.; 2 Thess. ii.; Exod. ix. Quod attinet ad ultimum effectum, nempe aeternam damnationem, patet ejus causam esse demerita humana ex ipsa forma sententiae latae in judicio finali.
