I think we can all hopefully agree that we should confess our sins frequently, and any mortal sins that we commited before, because as the name suggests this is about forgotten sins and to forget about a mortal sin is not a great reflection on ourselves, not to say someone isnt doing good examinations or anything but as the saints have told us, that daily examinations are very necessary because it is very easy to forget about things we have done before, as even the small things in the spiritual life are important because once we eradicate the little sins it would be fair to say we are more likely to avoid the serious sins.
An examination you do might be great but if it is a constant thing in our daily lives then we risk letting short comings pass through unnoticed so we must be vigilant. satan is satan for a reason, so if we let him in through the little things we take for granted he’ll have much more control over us than we might have thought.
Theres no point getting frustrated about this surely we have to confess our mortal sins if we didnt them yesterday, a month or a year ago because they are mortal (we earn ourselves loss of Heaven), why risk that. Some might have a fear of going to confession, but that shows we have contrition because we are doing something we may not look forward to (although that should be the opposite feeling), but if we dont go and try to justify ourselves and say “well . . it probably wasnt even mortal” then it shows cowardice and pride, signs of lack of sorrow and understanding of the seriousness of sin.
The Catechism teaches we need to confess mortal sins and not recieve until doing so, so we need to avoid recieving the Eucharist until then, it teaches that if we do a good confession while forgetting some mortal sin we may continue on as usual, but that is considering if we tried to the best of our ability to remember our sins, we should always seek the aid of the Holy Spirit when doing this “Come Holy Spirit fall afresh on me” or some prayer of invoking that God will help us, as “with men it is impossible”, so to have done badly our Holy Communions in that time were done badly, sacrilegous if fact, so we need to confess the sins and we need to confess the sacrilege, “but what if I didnt commit a sacrilege?” - well best to be sure isnt it, it will also show you are sorry for it, or at least would have if you commited them, only God knows, so there is no point asking others, as we dont even know ourselves sometimes. So confess it, if you have doubts confess it anyway because you’ll only do good for yourself and not risk losing anything important for all eternity because of pride or carelessness.
Dont be scared to confess your sins or ashamed, and dont sugar coat them! (dont go into too much detail either though)
Confess your sins, confess them well, confess the ones you forgot and confess the ones your not too sure anyway it’ll do no harm (as if you did do it their forgiven, if not it shows you care about the soul God has given you and that you wont leave things to chance)
Whatever you do when a forgotten mortal sin comes to mind do recieve our Lord until Confession, why cant you wait 1 hour or hopefully when you get to the priest asap !? (you think this is going too far, this is your soul we’re talking about, would you not rush to the hospital with a mortal wound, well a mortal sin is a tad more mortal) why risk commit sacrilege? - “perhaps it wasnt a mortal sin and I wont commit sacrilege?” - would you risk that.
trust me I know about this stuff so please just go to Confession and go often even if you havent commited a serious sin, weekly we are advised by Padre Pio and montly at least he tells us. Why wait until we are in danger until we seek safety.
Reading about the saints and their writings is great for increased devotion, motivation, and fervour, its contagious!!
God bless you
