John 20:21 - before He grants them the authority to forgive sins, Jesus says to the apostles, "as the Father sent me, so I send you." As Christ was sent by the Father to forgive sins, so Christ sends the apostles and their successors to forgive sins.
John 20:22 - the Lord "breathes" on the apostles, and then gives them the power to forgive and retain sins. The only other moment in Scripture where God breathes on man is in Gen. 2:7, when the Lord "breathes" divine life into man. When this happens, a significant transformation takes place.
John 20:23 - Jesus says, "If you forgive the sins of any, they are forgiven. If you retain the sins of any, they are retained." In order for the apostles to exercise this gift of forgiving sins, the penitents must orally confess their sins to them because the apostles are not mind readers. The text makes this very clear.
The hiearchy of the Catholic church is unscriptural in their current establish(ment)
On the contrary, the hierarchy of the Catholic Church was created by Jesus Christ, the author of Scripture.
Mark 3:16; John 1:42 – Jesus renames Simon "Kepha" in Aramaic which literally means "rock." This was an extraordinary thing for Jesus to do, because "rock" was not even a name in Jesus' time. Jesus did this, not to give Simon a strange name, but to identify his new status among the apostles. When God changes a person's name, He changes their status.
Gen. 17:5; 32:28; 2 Kings 23:34; Acts 9:4; 13:9 - for example, in these verses, we see that God changes the following people's names and, as a result, they become special agents of God: Abram to Abraham; Jacob to Israel, Eliakim to Jehoiakim, Saul to Paul.
2 Sam. 7:16; Psalm 89:3-4; 1 Chron.17:12,14 - God promises to establish the Davidic kingdom forever on earth.
Matt. 1:1 - Matthew clearly establishes this tie of David to Jesus. Jesus is the new King of the new House of David, and the King will assign a chief steward to rule over the house while the King is in heaven.
Luke 1:32 - the archangel Gabriel announces to Mary that her Son would be given "the throne of His father David." In using the term "keys," Jesus was referencing Isaiah 22 (which is the only place in the Bible where keys are used in the context of a kingdom).
Isaiah 22:22 - in the old Davidic kingdom, there were royal ministers who conducted the liturgical worship and bound the people in teaching and doctrine. But there was also a Prime Minister or chief steward of the kingdom who held the keys. Jesus gives Peter these keys to His earthly kingdom, the Church. This representative has decision-making authority over the people - when he shuts, no one opens. See also Job 12:14.
Rev. 1:18; 3:7; 9:1; 20:1 - Jesus' "keys" undeniably represent authority. By using the word "keys," Jesus gives Peter authority on earth over the new Davidic kingdom Matt. 16:19 - Jesus gives Peter the "keys of the kingdom of heaven."
These are Jesus' own apostles, not just any man. No man has the authority to forgive sins over Jesus... Furthermore, by setting up a system in which people are taught you have to confess your sins to a priest is not only wrong, it's a slap in the face to God who who set up the ONLY way for man to be forgiven his sins was by the brutal death of HIS son, our SAVIOR. To not go directly to him yourself, has to be quite an insult. Think about this.
