“Have you sinned? Go into Church and wipe out your sin. As often as you might fall down in the marketplace, you pick yourself up again. So too, as often as you sin, repent your sin. Do not despair. Even if you sin a second time, repent a second time. Do not by indifference lose hope entirely of the good things prepared. Even if you are in extreme old age and have sinned, go in, repent!” …. “For here there is a physician’s [i.e. the priest’s] office, not a courtroom; not a place where punishment of sin is exacted, but where the forgiveness of sin is granted.”

St. John Chrysostom – Homilies on Penance 3:4
