I know that we go to confession for our sins whether they're big or small. I do this. I believe that this is good from time to time. However, after confession is over, I walk with the impression that what I did wrong is over. I repented and I was forgiven. I said my prayers after and it's over. It becomes the past. I learn from it and try to avoid repeating it. Now, that 's all fine and dandy, but what happens to one's "sin" when an unhappy person comes to you and reminds you of the past and recalls the "sin" you committed? This unhappy person remembers your wrongs and didn't forgive you all these years. How does one cope with this especially after having confessed the "sin" to the priest? Should this person ask for forgiveness again? Is the forgiveness from the confession room valid if someone else brings it up again? Didn't the sin go away? Why is it that the thought of the sin comes back? Didn't God forgive me in that confession room? Why is he allowing the devil to torture me for the wrong I did. Wasn't my confession sincere enough? Didn't I suffer enough? I find myself confessing and then discover people who recall the bad that I did. What should I tell these people? Should I say this: I have confessed that already, so it's done and forgotten."
What is the value of confession if someone else in one's life brings back the past?
It looks like the posters' answers do not really address your question.
So someone - either a person whom you sinned against directly, or someone who was at least aware of your sin, brings it up in the future, after you have confessed.
It would seem, from those facts, that the person has a reason to bring it up again; the question is, what is their reason for doing so?
If it was someone whom you sinned against, it would appear that they have not forgiven you. This could be due to you not apologizing (if you didn't); or there was some harm that has not been made right (for example, you destroyed their property and did not make that right - the "baseball through the window"). Then make it right.
It may be that you have done what you could, but they still have anger or pain (or both) over it. Then very quietly, and very politely, ask them what you can do to make it right. Try to have some sort of conversation with them to get to what it takes for them to forgive and "put it behind their back (Isaiah). Try as hard as you can to come to some conclusion with them.
If they will not reconcile with you, then I would tell them (since this seems to be bothering you greatly) that you have apologized and done what you can to rectify the matter, and that if they will not drop it, you will either no longer respond to them about it, or if they pursue it, you will walk away. Then do so.
I had a relative who decided to rag me about something. We talked, they were angry, and I finally told them the matter was over and they had to get past it too.
They didn't, and it came up again at their house; and I literally got up and walked out the door. They finally got the message, and it has not been brought up since. Had I not gotten up right then and walked out, I suspect it would still be going on. I only did so after I had exhausted all possible avenues.
We have a duty to reconcile with those we have hurt. They also have a duty to reconcile with us, and sometimes that takes a long time. If they simply won't, than at some point we have to indicate that they do not have permission any longer to hold it over us and continue to bring it up.
If it is a friend, then honestly, they are telling you that you are no longer a friend. Move on.
If it is a spouse, then get counseling - both of you. There needs to be peace.
