Thank you. I have a practice of repeating confessions anyhow, since I was told by a SSPX priest that confessing sins that have already been confessed shortens ones time in Purgatory.
Well, that is true of course, especially if you have no other sins to confess.
But it should definitely not be done out of scrupulosity or continuous uncertainty on the validity. It would be better have one father confessor whom you can absolutely trust and tell the
whole state of your soul, and then faithfully accept his guidance.
Not trying to be a schoolmaster here, but that is pretty much what "the books" would tell :wink:
