Cap. IX Arg. 8 Sol cont.: they wrongly slide from reprobation to damnation — two things hanging on diverse causes
Lastly: in this argument they wrongly slide from reprobation to damnation itself, and try to mix and confuse the two — which we have already shown hang on diverse causes. Nor do we grant that, on the hypothesis always approved by the Catholic Church's judgment — that some are damned for original sin alone — it follows God deals more rigidly with such than with the very demons. A judge is not said to deal more rigidly with a lesser offender than with the worst traitor merely because he condemns both, unless he afflicts the one held by the lesser crime with equal or greater punishment.
Latin
Ultimo, perperam in hoc argumento transcursunt a reprobatione ad ipsam damnationem, et haec duo inter se commiscere et confundere conantur, quae ex diversis causis pendere supra ostendimus. Neque tamen damus illis, posita hac hypothesi (quae Catholicae Ecclesiae judicio semper fuit approbata) Damnari nonnullos propter solum originale peccatum, inde consequi Deum rigidius agere cum talibus, quam cum ipsis diabolis. Non enim dicimus judicem rigidius agere cum minore reo quovis, quam cum deterrimo proditore, quod utrumque damnet, nisi eum, qui minore peccato tenetur, pari aut majori supplicio afficiat.
