The Sacrament of Reconciliation is not "salvation through works." It is allowing yourself the graces instituted by Jesus, through the Apostolic Succession, to help put our feet back on the path to righteousness.
Sure, YOU can do this on your own, but I compare it to building a house. I might be able to accomplish it by myself, but it would take an incredible amount of time, I'd make a LOT of mistakes, and I'd probably waste a lot of money. To me, it would make more sense to hire a contractor.
The priest, LOL, is the contractor here. You don't confess to the priest, you aren't "forgiven" by the priest. He is serving as God's ears, and it is GOD who forgives your sins. As the saying goes, "don't knock it until you've tried it." First, you are really putting your ego on the line to actually admit, out loud, that you have done wrong. It's almost embarassing, but ONLY to you, because the priest has heard just about everything in the world before. It's very humbling to admit your failings to another person, even MORESO to admit them to God. Then, the priest usually asks you about the sins you've committed. What were the circumstances, how did it happen? You gain insight to your behavior with this conversation. "Gee, if I hadn't been the one to volunteer to keep the cashbox, then I wouldn't have been tempted to help myself to the money." The priest is there to HELP you gain that insight. Then he will often offer suggestions on how to avoid the temptation of sins. You most likely will be given a penance, too, but that is NOT something you do to "earn" forgiveness. It's to make you focus on God, to re-establish your relationship with Him. When you screw up, it's a very natural reaction to want to turn away, out of shame and fear. The penance makes you face Him again.
Then the priest absolves you of your sins, in the name of the Father, and of the Son, and of the Holy Spirit.
And you almost FLY out of the Confessional!
Incredible!!
Peace be with you,
