Confession: Why Tell Your Sins to a Priest?
Jesus gave His apostles the authority to forgive or retain sins on Easter evening (John 20:21-23). The bilateral structure — forgive or retain — implies a judicial function requiring the penitent to confess. Matthew 9:8 records that God gave this authority to "men" (plural). The Didache (c. A.D. 70), Origen, Chrysostom, and Ambrose all attest sacramental confession as the normal apostolic practice. The priest does not compete with God in forgiving — he is the instrument through which God speaks His absolution audibly and certainly to the penitent.
The Objection That Feels Obvious
Of all the distinctively Catholic practices, sacramental confession may generate the most immediate Protestant resistance. The objection feels self-evident: why confess sins to a man when you can go directly to God? Why do you need a priest as a middleman? Is this not an intrusion between the soul and its Creator — a human invention layered over the simple Gospel of forgiveness?
It is a serious objection, and it deserves a serious answer. That answer begins not with Catholic tradition, but with the words of Jesus Christ on the evening of the first Easter.
John 20:21–23: The Commission That Cannot Be Explained Away
“Jesus said to them again, ‘Peace be with you. As the Father has sent me, even so I send you.’ And when he had said this, he breathed on them and said to them, ‘Receive the Holy Spirit. If you forgive the sins of any, they are forgiven them; if you retain the sins of any, they are retained.’”
— The Risen Christ to His Apostles
Three things make this passage remarkable. First, the setting: the risen Christ, on the very evening of the Resurrection, chooses this as one of the first things to do. He breathes on the apostles — echoing God breathing life into Adam in Genesis 2:7 — and bestows authority over sin.
Second, the structure: the authority is bilateral. The apostles can forgive sins or retain them. This is not a general announcement that God forgives the repentant. A preacher who simply proclaims “God forgives the repentant” has no meaningful ability to retain anyone’s sins. The bilateral structure implies a judicial function — a genuine act of discernment about whether absolution is to be given.
Third, the implication: in order for the apostles to exercise this power justly — to know whether to forgive or to retain — they need to know the sins. They cannot read minds. The penitent must confess. The logic of the commission demands auricular confession as its natural mechanism.
Matthew 18:18 and the Keys of the Kingdom
This is not an isolated text. Earlier in John’s Gospel, Jesus had already given Peter the “keys of the kingdom of heaven” with the authority to bind and loose (Matthew 16:19). In Matthew 18:18, he extends this binding and loosing authority to the apostolic college as a whole: “Whatever you bind on earth shall be bound in heaven, and whatever you loose on earth shall be loosed in heaven.”
In the rabbinic tradition that Jesus was speaking into, “binding and loosing” had a precise technical meaning: the authority to declare what is permitted and what is forbidden, what is forgiven and what is not. Jesus is granting the apostles a share in His own authority to forgive — the same authority He exercised publicly when He said to the paralytic, “Your sins are forgiven” (Mark 2:5).
When the crowd witnessing the healing of the paralytic “glorified God, who had given such authority to men” (Matthew 9:8), they were not wrong to use the plural. Matthew records it deliberately. The authority to forgive sins was given by Christ to human ministers — to men, plural. The question is not whether this happened, but whether it continued past the apostolic generation.
Nothing in Scripture suggests this authority was intended to die with the Twelve. Apostolic succession — the laying on of hands transmitting the apostolic office — is itself attested in the New Testament (1 Timothy 4:14; 2 Timothy 1:6; Titus 1:5). If the office continues, the authority it carries continues with it.
What the Early Church Practiced
The New Testament witness is confirmed immediately by the earliest post-apostolic writings. The practice of confession to a priest or bishop is not a medieval innovation. It appears in the oldest Christian documents outside the New Testament.
The Didache (c. A.D. 70) — “Confess your sins in church, and do not go up to your prayer with an evil conscience.” This document predates most of the New Testament epistles.
Origen of Alexandria (A.D. 185–254) — “A final method of forgiveness… the remission of sins through penance, when the sinner does not shrink from declaring his sin to a priest of the Lord.”
St. John Chrysostom (A.D. 387) — “Priests… can bind with a bond which pertains to the soul itself and transcends the very heavens… ‘Whose sins you shall forgive,’ He says, ‘they are forgiven them.’ What greater power is there than this?”
St. Ambrose (A.D. 384–397) — “It seemed likewise impossible for sins to be forgiven through penance; yet Christ granted even this to His Apostles, and by His Apostles it has been transmitted to the offices of priests.”
Not one of the early Fathers teaches that private, direct confession to God is the ordinary means of receiving forgiveness for serious sin. The unanimous practice is sacramental absolution through the ministry of the Church.
The Objections Answered Directly
The scribes said the same thing to Jesus in Mark 2:7 — and He did not dispute the principle. He affirmed it, then demonstrated that the Son of Man has the authority on earth to forgive sins, and passed that authority to human ministers. God forgives through the priest’s absolution, just as He healed through the apostles’ hands. The instrument does not compete with the agent.
Catholics are encouraged to go directly to God in prayer and acknowledge their sins daily. But daily examination of conscience is not the same as sacramental absolution for grave sin. John 20:23 gives apostolic ministers a specific authority over sin — an authority that implies a specific act of absolution, not merely a general divine inclination to forgive the repentant.
Why It Is Actually a Mercy
Beyond the theological argument lies a pastoral reality that any honest Catholic convert will confirm: the confessional is not an obstacle to grace. It is its most concentrated human encounter.
To hear the words “I absolve you from your sins, in the name of the Father, and of the Son, and of the Holy Spirit” spoken aloud, addressed to you by name, after you have named your worst self and found it met with mercy — this is not a bureaucratic formality. It is the closest thing on earth to hearing Christ say to the paralytic, “Your sins are forgiven.”
“The sinner who approaches this sacrament meets not a judge, not a bureaucrat, but a physician. The Church is a hospital for the sick, not a museum for the righteous. And in the confessional, every wound — no matter how deep — can be healed.”
— A principle running throughout the tradition from Chrysostom to Francis
The genius of sacramental confession is that it takes the mercy of God and makes it concrete, audible, personal, and certain. You do not leave the confessional wondering if God heard you, or whether your contrition was sufficient, or whether you are truly forgiven. You leave with the words of absolution spoken over you, in the name of the Trinity, by a minister appointed by Christ for precisely this purpose. The Church did not invent this sacrament. She received it — from her Lord, on the evening He rose from the dead.
