If you commit a mortal sin(s) and then you go to confession and confess, but you forget to mention a particular sin that is mortal, then after receiving communion for a couple of weeks remember that mortal sin which you forgot to confess, would you be profaning the Body of Christ if you didn’t go to confession before the next time you received communion?
I ask because, I saw something which reminded me of a sin (I’ll assume worst case scenario, so let’s say it is mortal), which I had not confessed because I forgot it. Only now, a few weeks after confession, I remembered it. Now, would I be able to receive communion worthily without confessing that sin anymore? Or could I receive communion and just confess it the next time I go to confession (in a couple of weeks)? Or would I be in a state of mortal sin now that I have remembered it?
