Whether a general confession suffices to blot out forgotten mortal sins?

❌ Objection 1 : It would seem that a general confession does not suffice to blot out forgotten mortal sins. For there is no necessity to confess again a sin which has been blotted out by confession. If, therefore, forgotten sins were forgiven by a general confession, there would be no need to confess them when they are called to mind.

❌ Objection 2 : Further, whoever is not conscious of sin, either is not guilty of sin, or has forgotten his sin. If, therefore, mortal sins are forgiven by a general confession, whoever is not conscious of a mortal sin, can be certain that he is free from mortal sin, whenever he makes a general confession: which is contrary to what the Apostle says (1 Cor. 4:4), "I am not conscious to myself of anything, yet am I not hereby justified."

❌ Objection 3 : Further, no man profits by neglect. Now a man cannot forget a mortal sin without neglect, before it is forgiven him. Therefore he does not profit by his forgetfulness so that the sin is forgiven him without special mention thereof in confession.

❌ Objection 4 : Further, that which the penitent knows nothing about is further from his knowledge than that which he has forgotten. Now a general confession does not blot out sins committed through ignorance, else heretics, who are not aware that certain things they have done are sinful, and certain simple people, would be absolved by a general confession, which is false. Therefore a general confession does not take away forgotten sins.
