John 20
21 Again Jesus said, Peace be with you! As the Father has sent me, I am sending you.
22 And with that he breathed on them and said, Receive the Holy Spirit.
23 If you forgive anyone his sins, they are forgiven; if you do not forgive them, they are not forgiven.
Some one of a different religion to me once told me something that is very true. The best way to understand what Jesus meant when he told his disciples things is to look at how the disciples carried it out. If God was giving the disciples the authority to forgive sins on Jesus' behalf then they would have done so. NONE OF THE DISCIPLES ever encouraged anyone to confess their sins to them. They never had a special times for confession and forgiveness of people's sins. They never assumed any authority to forgive sins. It is either they just disobeyed or Jesus did not mean that they had the power to forgive sins. But Paul coming after definitely knew that that was not what God meant. He wrote the book of Hebrews didn't he. This is what he said.
Heb 8:1 Now of the things which we have spoken this is the sum: We have such a high priest, who is set on the right hand of the throne of the Majesty in the heavens;
Heb 8:2 A minister of the sanctuary, and of the true tabernacle, which the Lord pitched, and not man.
Heb 9:24 For Christ is not entered into the holy places made with hands, which are the figures of the true; but into heaven itself, now to appear in the presence of God for us:
Heb 9:25 Nor yet that he should offer himself often, as the high priest entereth into the holy place every year with blood of others;
Heb 9:26 For then must he often have suffered since the foundation of the world: but now once in the end of the world hath he appeared to put away sin by the sacrifice of himself.
Jesus is our heavenly high priest. He is the mediator between God and man. Before Jesus the earthly high priest was the mediator but now in the new covenant Jesus is our high priest. He fulfills everything the earthly high priest used to do and he did and is doing them much better.
1Ti 2:5 For there is one God, and one mediator between God and men, the man Christ Jesus;
Only one mediator and that is Jesus and not any earthly priest, He makes intercession for us.
Heb 7:25 Wherefore he is able also to save them to the uttermost that come unto God by him, seeing he ever liveth to make intercession for them.
No wonder Peter did not tell anyone to confess their sins to him to be forgiven. He pointed them to someone else.
Act 2:37 Now when they heard this, they were pricked in their heart, and said unto Peter and to the rest of the apostles, Men and brethren, what shall we do?
Act 2:38 Then Peter said unto them, Repent, and be baptized every one of you
in the name of Jesus Christ for the remission of sins, and ye shall receive the gift of the Holy Ghost.
I guess he was paying attention when Jesus said:
Mat 26:28 For this is my blood of the new testament, which is shed for many for the remission of sins.
He nor any other disciple or apostle pointed anyone to them to obtain forgiveness for their sins. It must be that they knew that they did not have the power to forgive sins but only the man Christ Jesus can forgive sins. John who was with Jesus who was there when Jesus spoke in verse 23 said this.
1Jo 1:9 If we confess our sins, he is faithful and just to forgive us our sins, and to cleanse us from all unrighteousness.
1Jo 1:1 That which was from the beginning, which we have heard, which we have seen with our eyes, which we have looked upon, and our hands have handled, of the Word of life;
He did not say that you have an advocate with him but with the father. The point is that when we sin we don't sin against the priest we sin against God and against the person we did wrong based on the sin. Only those persons can forgive us.
