" If sin is quantified, then we look to merits or graces as the remedy. Baptism atones for original sin, or the sin of Adam that was imputed to us. What remains is our actual sins. Again, the quantity of sins is the issue. And so, the other sacraments, in addition to the sacrament of baptism, come into play. Through penance, it is possible to undo the effects of our sins. "
