Oh, if only I were as devout as you say! It's been six weeks for me, and if I don't go tomorrow I will feel I've got a terrible back-inventory to account for.
You might more accurately have asked, "Why do really devout, holy Catholics --- for instance, many of the canonized saints --- go to Confession every week????"
I suppose for the same reason I wash my dishes on a fairly regular basis, launder my clothes, and weed my garden: because these things call for constant maintenance.
When I was a know-it-all quasi-Catholic-pagan at age 18, 20, 22 (i.e. back in the Jurassic) I went for, as I remember, years without Confession, though my sins were as Crayola Red. Now that I'm back in the fold, I find myself more and more aware of my faults.
Age does that.
Marriage, too... :o)
my understanding of confession is that one is supposed to confess your sins....the ones you committed since the last time you were at confession. Now if you have done your penance and truly repented then your behavior would have changed so why are you back at confession again????
