   • 412 CE – 426 CE, Aurelius Augustinus Hipponensis, City of God 12.1:

     Sīcut ergō, cum vitium oculōrum dīcitur caecitās, id ostenditur, quod ad nātūram oculōrum pertinet vīsus; et cum vitium aurium dīcitur surditās, ad eārum nātūram pertinēre dēmōnstrātur audītus: ita, cum vitium creātūrae angelicae dīcitur, quō nōn adhaeret Deō, hinc apertissimē dēclārātur, eius nātūrae ut Deō adhaereat convenīre.

     As, then, when we say that blindness is a defect of the eyes, we prove that sight belongs to the nature of the eyes; and when we say that deafness is a defect of the ears, hearing is thereby proved to belong to their nature;—so, when we say that it is a fault of the angelic creature that it does not cleave to God, we hereby most plainly declare that it pertained to its nature to cleave to God.
