We are not sinners because we sin. We sin because we’re sinners.
It’s a good thing to confess the particular sins, but they are simply the leaves on the weeds. The weed has deep roots that go down into the depth of our soul, and the point of confession and the Catholic faith is to open our hearts and lives to the healing and forgiveness that we need at the depth of our being. St Augustine teaches that original sin wounds the image of God in us, and it is this wound that needs healing.
