So to be clear here, if I go to confession, forget some sin from my past that is mortal, I am forgiven for all sins at that confession even if I don’t confess them (not on purpose)?
I ask because I was gone from the church for a long time and there was a lot of stuff that happened during that time. Obviously I went to confession when I first came back to the church, and go regularly now. Yet every once in a while something from my past pops up in my memory. Do I still need to confess those sins now, or has all that been covered in the confession(s) I have done since returning? I ask, because I just don’t know. I have been confessing these things as they come along, but the last time I brought up an old sin the priest told me to let it go, and not to bring up those old things anymore. And I’d like to do that, but want to make sure I’m confessing things properly.
