I agree with puzzleannie’s last remarks, and would add that it is always a good idea to remind people that if they are in a state of mortal sin, it would another mortal sin to recieve communion. I strongly believe that spreading the word about this particular point is essential to the future of the church.
The other day, I spoke with a woman I know who said that she hadn’t been to confession in about 20 years, and wondered why we really needed it. To make things worse, she regularly receives communion.
Some parish priests have begun doing something very positive in this respect: they are placing little pamphlets explaining how to go to confession, why to go, what is a mortal sin, etc. I like to take a Socratic approach to this problem, and think that most wrongdoings regarding confession stem from ignorance rather than a deliberate desire to disobey.
