Earlier post: I was told by someone that going Monday fulfilled the Sunday
obligation I hope that’s true cuz I was planning on going to mass tomorrow and taking communion. since I was
under the impression that going Monday for fulfilled the Sunday obligation I think that keeps me out of mortal
sin does that sound right?
Going to mass on the Monday wouldn't have fulfilled the Sunday mass obligation.
However, if you believed this was so, there was no sin on your part for going to mass Monday only. People can
only sin if they were aware thing something they did involved wrongdoing. Otherwise, of course, you could take
care of this quite well by going to confession.
