Light And Illumination

Omnia autem quae objurgantur, a lumine manifestantur.... Quia praeceptum dedit ut et objurgent male facientes, adjuecti quantum sit munus objurgatio: quoniam peccata illa in occulto, quasi lumine manifestantur cum objurgantur. Is enim qui objurgat, ostendit quantum malum sit illud quod objurgat: et dum ostendit, quasi illuminat malum: quod cum intellixerit ille qui admittit, discutit tenebras et ad lumen accedit. Omne enim quod manifestatur, lumen est. Ostendit ipse, quod exposuimus. Intellectum enim quodcumque est, et manifestatur, et lux est, et videtur, et apertum. Victorinus Afrus, In Epistolam Pauli ad Ephesios, Liber Secundus, Cap V Source: Migne PL 8.1285c

All things which are chastised are made manifest by light... 1 Because he has given the teaching that they should chastise all who do evil, he adds how great the gift of chastisement may be, that is, that when hidden sins are chastised they are made manifest as by light. The one who chastises shows how much evil there is in what he chastises, and while he shows it, it is as he illuminates the evil, because when the other understands, he who admits it, he drives off the darkness and comes to the light. 'Everything which is made manifest is light.' 1 Which shows what we have explained. For that which is understood is made manifest, and it is light, and it appears, and it is revealed. Victorinus Afrus, On the Epistle of Saint Paul to the Ephesians, Book Two, Chapter Five 1 Ephes 5.13
