This may help, especially if you’re committing the same sins over and over:
VATICAN CITY, OCT. 20, 2005 (Zenit.org).- Here is the catechesis that Benedict XVI addressed last Saturday afternoon to children who were receiving their First Communion this year.
Livia: “Holy Father, before the day of my First Communion I went to confession. I have also been to confession on other occasions. I wanted to ask you: Do I have to go to confession every time I receive Communion, even when I have committed the same sins? Because I realize that they are always the same.”
Benedict XVI: "I will tell you two things…it is not necessary to make one’s confession before every Eucharistic Communion. This is the first point. It is only necessary when you have committed a really serious sin, when you have deeply offended Jesus, so that your friendship is destroyed and you have to start again.
My second point: It is true: Our sins are always the same, but we clean our homes, our rooms, at least once a week, even if the dirt is always the same; in order to live in cleanliness, in order to start again. Otherwise, the dirt might not be seen but it builds up."
Simple language, profound theology.
So, I think even the Pope undestands that we all have certain “pet” sins that we have problems with on a chronic basis. I know I do, and if people are honest with themselves, they know that they do, too. Some sins you just have trouble getting rid of and keeping out, the same way you have trouble keeping dust from building up in the house.
That’s why we have confession to begin with: to clean the house when it gets dirty, even if it’s the exact same dirt, week after week.
