Whether venial sins are forgiven through this sacrament?

Objections

Objection 1 : It seems that venial sins are not forgiven by this sacrament, because this is the "sacrament of charity," as Augustine says (Tract. xxvi in Joan.). But venial sins are not contrary to charity, as was shown in the FS, Question [88], Articles [1],2; SS, Question [24], Article [10]. Therefore, since contrary is taken away by its contrary, it seems that venial sins are not forgiven by this sacrament.
Objection 2 : Further, if venial sins be forgiven by this sacrament, then all of them are forgiven for the same reason as one is. But it does not appear that all are forgiven, because thus one might frequently be without any venial sin, against what is said in 1 Jn. 1:8: "If we say that we have no sin, we deceive ourselves." Therefore no venial sin is forgiven by this sacrament.
Objection 3 : Further, contraries mutually exclude each other. But venial sins do not forbid the receiving of this sacrament: because Augustine says on the words, "If any man eat of it he shall [Vulg.: 'may'] not die for ever" (Jn. 6:50): "Bring innocence to the altar: your sins, though they be daily . . . let them not be deadly." Therefore neither are venial sins taken away by this sacrament.
