In no wise are the bodies themselves to be spurned. (...) For these pertain not to ornament or aid which is applied from without, but to the very nature of man.[34]
De cura pro mortuis gerendaCSEL 41, 627[13–22]; PL 40, 595: Nullo modo ipsa spernenda sunt corpora. (...)Haec enim non ad ornamentum vel adiutorium, quod adhibetur extrinsecus, sed ad ipsam naturam hominis pertinent; Contra Faustum, 22.27; PL 44,418.
Augustine taught that Adam's sin was both an act of foolishness (insipientia) and of pride and disobedience to God of Adam and Eve. He thought it was a most subtle job to discern what came first: self-centeredness or failure in seeing truth. Augustine wrote to Julian of Eclanum: Sed si disputatione subtilissima et elimatissima opus est, ut sciamus utrum primos homines insipientia superbos, an insipientes superbia fecerit (Contra Julianum, V, 4.18; PL 44, 795). This particular sin would not have taken place if Satan had not sown into their senses "the root of evil" (radix Mali): Nisi radicem mali humanus tunc reciperet sensus (Contra Julianum, I, 9.42; PL 44, 670)
"Original Sin" (页面存档备份,存于互联网档案馆). Biblical Apologetic Studies. Retrieved 17 May 2014. Augustine of Hippo (354–430) taught that Adam's sin is transmitted by concupiscence, or "hurtful desire", sexual desire and all sensual feelings resulting in humanity becoming a massa damnata (mass of perdition, condemned crowd), with much enfeebled, though not destroyed, freedom of will.
Thomas Aquinas explained Augustine's doctrine pointing out that the libido (concupiscence), which makes the original sin pass from parents to children, is not a libido actualis, i.e. sexual lust, but libido habitualis, i.e. a wound of the whole of human nature: Libido quae transmittit peccatum originale in prolem, non est libido actualis, quia dato quod virtute divina concederetur alicui quod nullam inordinatam libidinem in actu generationis sentiret, adhuc transmitteret in prolem originale peccatum. Sed libido illa est intelligenda habitualiter, secundum quod appetitus sensitivus non continetur sub ratione vinculo originalis iustitiae. Et talis libido in omnibus est aequalis (STh Iª–IIae q. 82 a. 4 ad 3).
Non substantialiter manere concupiscentiam, sicut corpus aliquod aut spiritum; sed esse affectionem quamdam malae qualitatis, sicut est languor. (De nuptiis et concupiscentia, I, 25. 28; PL 44, 430; cf. Contra Julianum, VI, 18.53; PL 44, 854; ibid. VI, 19.58; PL 44, 857; ibid., II, 10.33; PL 44, 697; Contra Secundinum Manichaeum, 15; PL 42, 590.
