To Hoonbaba:
Your confusion is understandable. Not to worry, though.
There are two kinds of sin, venial sin and mortal sin. Venial sin is the stupid stuff we all do that we know is wrong, and we should stop doing, but it sneaks out. Not giving back the money when the cashier mistakenly counts our change wrong, leaving the mess in the kitchen for someone else to clean up, screaming at the kids when it's really the crummy day at work you're upset about, giving that jerk "the finger" when you get cut off in traffic....you know the type of stuff I'm talking about here.
Mortal sin is the biggie stuff....if you die while you are committing a mortal sin, you're going straight to Hell in the proverbial handbasket. Murder is always a good one.
99% of the stupid, sinful things we do, though, fall in between those two extremes. And as you know from personal experience, when you start doing something you KNOW is wrong, it opens the door to CONTINUE doing wrong. An example would be if you were a cashier, and you "borrowed" a couple of quarters from the till to make a phone call one day....if nobody hollered at the end of the day about the shortage, then the little devil on your shoulder would say the next day, "Hey, take a couple of bucks this time to pay for lunch!"
Confession is a counseling session. Yes, there is a "routine" which is followed for the confession and forgiveness of sins, but it's changed so much from the days of the old movies where a kid would kneel in a dark confessional and say, "BlessmefatherforIhavesinned, I hit my brother twice, I stole from my mother's purse, and I spit in the mashed potatoes." The priest behind the grille would make the Sign of the Cross, mutter some Latin, and then tell the kid to say "Five Hail Marys" and that is what Confession would be.
Today, you can still use the private confessional, or you can sit in a small private room with the door closed, and be face-to-face with the priest. You tell him, "I have been *borrowing* money from the cash register at work." The priest will say, "Tell me about it."
What it will end up is that you'll talk to the priest about what happened...how it started, why it continued. You'll probably get admonished, because, LOL, you KNOW you need the scolding! The priest will say, "How much money does this add up to?" And then you'll be told to either find a way to pay it back, or maybe even contribute that amount of money to charity. You'll probably be told to change your job duties, so you aren't confronted with that temptation again.
You'll be asked to make an "Act of Contrition." You'll either pray in your own words, that you are sorry for offending God, not because He has the power to give you the eternal punishment which you so justly deserve, but because offending Him HURTS GOD, and you have no business hurting The One who loves you so much....or the priest might have a little laminated card with the formal "Act of Contrition" prayer on it, and ask you to read it out loud.
Then the priest forgives your sins.........and you FLOAT OUT THE DOOR.
Inside the Church, you'll see people in the pews, kneeling in prayer. It's dimly lit, and very quiet. You might also slip into a pew, and kneel in your own prayer. Maybe the priest has given you some prayers to think about. For me, though, I'm almost doubled over in gratitude, THANKING GOD and PRAISING GOD for His incredible love and mercy.
Peace be with you,
