To Peter alone Jesus granted the first power to bind and loose anything.
Mt 16:19 Whatever you bind on earth shall be bound in heaven, and whatever you loose on earth shall be loosed in heaven. (NAB)To all the disciples Jesus later granted the same power to bind and loose.
Mt 18:18 I assure you, whatever you declare bound on earth shall be bound in heaven, and whatev- er you declare loosed on earth shall be loosed in heaven. (NAB)To all the disciples Jesus gave the power to forgive sins.
Jo 20:21-23 "Peace be with you," he (Jesus) said again. "As the Father has sent me, so I send you." Then he breathed on them and said: "Receive the Holy Spirit. If you forgive men's sins, they are forgiven them; if you hold them bound, they are held bound." (NAB)As can be seen from the nature of personal sin, as man turns from God and towards created things, man incurs both guilt and punishment. Through the blood of Jesus, all guilt of sin-- turning from God--is remitted through confession of sin. Punishment, limited temporal punishment due to sin-- preferring created things to God--still remains.
Num 14:20-23 The Lord answered (Moses): "I pardon them as you have asked. Yet, by my life and the Lord's glory that fills the whole earth, of all men who have seen my glory and the signs I worked in Egypt and in the desert, and who nevertheless have put me to the test ten times already and have failed to heed my voice, not one shall see the land which I promised on oath to their fathers. None of these who have spurned me shall see it." (NAB) 2 Sam 12:13-14 Then David said to Nathan, "I have sinned against the Lord." Nathan answered David: "The Lord on his part has forgiven your sin: you shall not die. But since you have utterly spurned the Lord by this deed, the child born to you must surely die." (NAB) 1 Cor 11:27-32 He who eats and drinks without recognizing the body eats and drinks a judgment on himself. That is why many among you are sick and infirm, and why so many are dying. If we were to examine ourselves, we would not be falling under judgment in this way; but since it is the Lord who judges us, he chastens us to keep us from being condemned with the rest of the world. (NAB) Prov 16:6 By kindness and piety guilt is expiated, and by the fear of the Lord man avoids evil. (NAB) Dan 4:24 Therefore, O king, take my advice; atone for your sins by good deeds, and for your misdeeds by kindness to the poor; then your prosperity will be long. (NAB) Act 10:4 Your prayers and your generosity have risen in God's sight, and because of them he has remembered you. (NAB)
