Can the Catholic Church Forgive Sins? The Authority Claim and Why It Doesn't Hold

Can the Catholic Church Forgive Sins? The Authority Claim vs Scripture

The Catholic Church claims the power to forgive sins through its priests. You sit in a confessional, tell a priest what you did, and he says "ego te absolvo" - I absolve you. But where does this claim come from, and does it hold up against what the Bible actually says?

The Foundation: Matthew 16:18-19

The entire Catholic authority structure rests on one conversation. Jesus says to Peter: "You are Peter, and on this rock I will build my church, and the gates of Hades will not overcome it. I will give you the keys of the kingdom of heaven; whatever you bind on earth will be bound in heaven, and whatever you loose on earth will be loosed in heaven."

From this, the Catholic Church claims:

Jesus gave Peter supreme authority over the church ("the keys")
Peter became the first bishop of Rome
Every Pope is Peter's successor, inheriting that authority in an unbroken chain
That authority includes the power to forgive sins, define doctrine, and act as Christ's representative on earth

They call it apostolic succession: authority passing from Peter to the next bishop of Rome to the next, like a spiritual monarchy. Pope Francis today claims to hold the same keys Jesus handed to Peter.

The Greek Tells a Different Story

Jesus says "on this rock I will build my church." Catholics say "this rock" is Peter the person. But the Greek is doing something precise. Peter's name is Petros (masculine, meaning a small stone or pebble). The word Jesus uses for "rock" is petra (feminine, meaning a large bedrock, a foundation). They're not the same word.

Many scholars read it as: you are Petros (a stone), and on this petra (bedrock) - meaning Peter's confession that Jesus is the Messiah - I will build my church. The rock isn't Peter. The rock is the truth Peter just spoke: "You are the Messiah, the Son of the living God" (Matthew 16:16). The church is built on that declaration, not on one man.

Peter Didn't Act Like a Pope

Paul publicly opposed him to his face (Galatians 2:11): "When Cephas came to Antioch, I opposed him to his face, because he stood condemned." You don't rebuke the infallible Pope in public. Paul didn't treat Peter like a superior. He treated him like an equal who was wrong.
Peter called himself "a fellow elder" (1 Peter 5:1). Not "the supreme elder." Not "the head of the church." A fellow elder. Among equals.
At the Council of Jerusalem (Acts 15), the most important early church decision, it was James who rendered the final verdict, not Peter. James said "it is my judgment" (Acts 15:19) and the council followed him. If Peter held the keys, why wasn't he making the call?

The Forgiveness Claim: John 20:23

The other key verse is John 20:23, where Jesus says to the disciples: "If you forgive anyone's sins, their sins are forgiven; if you do not forgive them, they are not forgiven."

Catholics read this as Jesus giving priests the literal power to absolve sins in confession. But look at who Jesus is talking to. Not priests. There was no priesthood yet. He's talking to the disciples, all of them. The context is the Great Commission: he's sending them out to preach the gospel. The "forgiving" and "retaining" of sins is about proclaiming the gospel message: those who believe are forgiven, those who reject it are not. It's a declaration of what God does, not a power the disciples hold independently.

What the Bible Actually Says About Who Forgives Sins

"Who can forgive sins but God alone?" (Mark 2:7) - Even the Pharisees knew this. Jesus proved he could forgive sins precisely because he IS God.
"If we confess our sins, he is faithful and just and will forgive us" (1 John 1:9) - Confess to HIM. Not to a priest.
"For there is one God and one mediator between God and mankind, the man Christ Jesus" (1 Timothy 2:5) - ONE mediator. Not one mediator plus thousands of priests.

The Priesthood Is Finished

The book of Hebrews spends entire chapters explaining that the old priesthood is over. Hebrews 7:27 says Jesus "does not need to offer sacrifices day after day, first for his own sins, and then for the sins of the people. He sacrificed for their sins once for all when he offered himself." The entire Levitical system of priests mediating between God and people ended at the cross.

Hebrews 10:19-22 says we can now "enter the Most Holy Place by the blood of Jesus" with "confidence" and a "sincere heart." No priest required. The veil tore. Direct access.

The veil in the temple tore from top to bottom when Jesus died (Matthew 27:51). Top to bottom means God tore it, not humans. The barrier between God and people was removed by God himself. The Catholic Church essentially re-stitched the veil and put a man in front of it charging admission.

Jesus warned about exactly this: "You have let go of the commands of God and are holding on to human traditions" (Mark 7:8). And "They worship me in vain; their teachings are merely human rules" (Mark 7:7, quoting Isaiah 29:13).
