Whether venial sin causes a stain on the soul?

❌ Objection 1 : It would seem that venial sin causes a stain in the soul. For Augustine says (De Poenit.) [*Hom. 50, inter. L., 2], that if venial sins be multiplied, they destroy the beauty of our souls so as to deprive us of the embraces of our heavenly spouse. But the stain of sin is nothing else but the loss of the soul's beauty. Therefore venial sins cause a stain in the soul.

❌ Objection 2 : Further, mortal sin causes a stain in the soul, on account of the inordinateness of the act and of the sinner's affections. But, in venial sin, there is an inordinateness of the act and of the affections. Therefore venial sin causes a stain in the soul.

❌ Objection 3 : Further, the stain on the soul is caused by contact with a temporal thing, through love thereof as stated above (Question [86], Article [1]). But, in venial sin, the soul is in contact with a temporal thing through inordinate love. therefore, venial sin brings a stain on the soul.
