Why do you say things like this? You know the Catholic Church does not make this stuff up just to annoy you, and that NOTHING the Church teaches is without Scriptural warrant if not specific ordinance. The gift of forgiving sins in Confession is clearly given in John 20:20-23 and demonstrated in 2 Cor. 2:10 where Paul declares that “I have forgiven” referring to the incestuous man. See also Jas 5:16.
You often cry “context” but for us “context” is not just the book but the actual practice of the early Church where confession in the presence of the priest was a universal practice.
Context and scriptural interpretation is best analyzed by comparing scripture…
Lets compare scripture to see what Jesus was saying here…Joh 3:11"Truly, truly, I say to you, we speak of what we know and testify of what we have seen, and you do not accept our testimony.
Joh 3:12"If I told you earthly things and you do not believe, how will you believe if I tell you heavenly things?
Joh 3:13"No one has ascended into heaven, but He who descended from heaven: the Son of Man.
Joh 3:14"As Moses lifted up the serpent in the wilderness, even so must the Son of Man be lifted up;
Joh 3:15so that whoever believes will in Him have eternal life.
Joh 3:16"For God so loved the world, that He gave His only begotten Son, that whoever believes in Him shall not perish, but have eternal life.
Joh 3:17"
For God did not send the Son into the world to judge the world, but that the world might be saved through Him.
Joh 3:18"He who believes in Him is not judged; he who does not believe has been judged already, because he has not believed in the name of the only begotten Son of God****.
Joh 3:19"This is the judgment, that the Light has come into the world, and men loved the darkness rather than the Light, for their deeds were evil.
Joh 3:20"For everyone who does evil hates the Light, and does not come to the Light for fear that his deeds will be exposed.
Joh 3:21"**But he who practices the truth comes to the Light, so that his deeds may be manifested as having been wrought in God."/**COLOR]Now we see that Jesus was sent to preach that if all believe in Him they are forgiven and have eternal life here. This is why the Father sent Him. Now lets look at the scripture you gave me…
Joh 20:21 So Jesus said to them again, “Peace be with you; as the Father has sent Me, I also send you.”
Joh 20:22 And when He had said this, He breathed on them and *said to them, “Receive the Holy Spirit.
Joh 20:23"If you forgive the sins of any, their sins have been forgiven them; if you retain the sins of any, they have been retained.”
Now we see here as the Father sent Jesus He sends the Apostles to do what? Preach Jesus… That all who believe in Him their sins are forgiven… Now this authority is given to the Apostles but lets look closely at it… What does Jesus say?
Joh 3:18"He who believes in Him is not judged; he who does not believe has been judged already, because he has not believed in the name of the only begotten Son of God.
This is the authority that Christ gave the Disciples… If they do not believe their testimony of Christ then they have the authority to say you are not forgiven. If they do believe their testimony they have the authority to say your sins are forgiven you…
