“In confession a man breaks through to certainty. Why is it that it is often easier for us to confess our sins to God than to a brother? God is holy and sinless, He is a just judge of evil and the enemy of all disobedience. But a brother is sinful as we are. He knows from his own experience the dark night of secret sin. Why should we not find it easier to go to a brother than to the holy God? But if we do, we must ask ourselves whether we have not often been deceiving ourselves with our confession of sin to God, whether we have not rather been confessing our sins to ourselves and also granting ourselves absolution. And is not the reason perhaps for our countless relapses and the feebleness of our Christian obedience to be found precisely in the fact that we are living on self-forgiveness and not a real forgiveness? Self-forgiveness can never lead to a breach with sin; this can be accomplished only by the judging and pardoning Word of God itself.
Who can give us the certainty that, in the confession and the forgiveness of our sins, we are not dealing with ourselves but with the living God? God gives us this certainty through our brother. Our brother breaks the circle of self-deception. A man who confesses his sins in the presence of a brother knows that he is no longer alone with himself; he experiences the presence of God in the reality of the other person. As long as I am by myself in the confession of my sins everything remains in the dark, but in the presence of a brother the sin has to be brought into the light. But since the sin must come to light some time, it is better that is happens today between me and my brother, rather than on the last day in the piercing light of the final judgment. It is a mercy that we can confess our sins to a brother. Such grace spares us the terrors of the last judgment. Our brother has been given me that even here and now I may be certain through him of the reality of God in His judgment and His grace. As the open confession of my sins to a brother insures me against self-deception, so, too, the assurance of forgiveness becomes fully certain to me only when it is spoken by a brother in the name of God. Mutual, brotherly confession is given to us by God in order that we may be sure of divine forgiveness. But it is precisely for the sake of this certainty that confession should deal with concrete sins. People usually are satisfied when they make a general confession. But one experiences the utter perdition and corruption of human nature, in so far as this ever enters into experience at all, when one sees his own specific sins.
Self-examination on the basis of all Ten Commandments will therefore be the right preparation for confession. Otherwise it might happen that one could still be a hypocrite even in confessing to a brother and thus miss the good of the confession.
Jesus dealt with people whose sins were obvious, with publicans and harlots. They knew why they needed forgiveness, and they received it as forgiveness of their specific sins. Blind Bartimaeus was asked by Jesus: What do you want me to do for you? Before confession we must have a clear answer to this question. In confession we, too, receive the forgiveness of the particular sins which are here brought to light, and by this very token the forgiveness of all our sins, known and unknown.”
