Over lunch, I read an article about sin and confession over at Fr Longenecker's blog. It was a good read especially where he was discussing how many of the sins we discount may be some of the most serious. Some of the most common examples are where he says:
".... to gossip and talk badly about others, to complain and grumble all the time and to be bitter and negative habitually may be far more serious because we ignore it and pretend we're not doing anyone any harm. At least with the big fight we feel bad and know it is a sin. With the casual gossip, back biting, nasty comments and negativity we often come away actually feeling better about ourselves."
All good food for thought. You can read the entire article here.
