Plenary Indulgences
What an indulgence remits, the conditions for a plenary one, and the misunderstanding everyone starts with
A plenary indulgence remits all the temporal punishment due to sins whose guilt has already been forgiven. It does not forgive sin, and it cannot be bought. To gain one you must perform the prescribed work and fulfil the usual conditions: sacramental confession, Holy Communion, and prayer for the intentions of the Holy Father — together with complete detachment from all sin, including venial sin. That last condition is the one that makes most attempts partial rather than plenary, and it is not a reason to stop trying.
Quick Summary
- Remits temporal punishment, never guilt — sin is forgiven in confession, not by an indulgence
- Plenary means all of that punishment; partial means some of it
- Usual conditions: confession, Communion, prayer for the Pope's intentions
- Plus complete detachment from all sin, even venial — the condition that decides it
- One plenary a day, except in danger of death
- May be applied to yourself or to the dead — never to another living person
- Cannot be bought; the sale of indulgences was condemned by the Church herself
Full Explanation
An indulgence is one of the most misunderstood things the Church does, and almost all of the confusion comes from a single mistake: thinking it has something to do with being forgiven. It does not. Guilt is forgiven in confession, and only there. What an indulgence touches is what remains after forgiveness — what the Church calls the temporal punishment due to sin. The intuition behind it is ordinary enough. If you break a neighbour's window and they forgive you, the window is still broken. Sin damages the person who commits it and the world around him, and being forgiven does not by itself undo that damage. The healing of it is what an indulgence applies to. A plenary indulgence remits all of that punishment; a partial indulgence remits some of it. In each case the Church is not performing a transaction but drawing on what tradition calls the treasury of merit — the superabundant satisfaction of Christ and of the saints — and applying it to someone who has done a prescribed act in the right disposition. The conditions are where people get stuck, partly because different sources count them differently. Three of them are the usual conditions and are always the same: sacramental confession, Eucharistic Communion, and prayer for the intentions of the Holy Father — traditionally an Our Father and a Hail Mary, though no particular prayer is required. To these is added the prescribed work itself, whatever act the indulgence is attached to. Some pages count four, some five, some three; they are describing the same thing and dividing it up differently. But there is a further condition, and it is the one that actually decides the matter: complete detachment from all sin, including venial sin. Not merely being sorry for it, and not merely intending to avoid it — being genuinely unattached to it, including the small habitual ones nobody thinks about. This is difficult, and honest teachers say so plainly. If any attachment remains, the indulgence is not lost; it becomes partial. That is worth knowing, because the alternative is people either presuming they have gained a plenary indulgence when they have not, or giving up on the practice because they cannot be sure. Neither is right. Do the work, fulfil the conditions, and leave the accounting to God. One further thing, because it is the reason many people are suspicious of the whole subject. Indulgences cannot be bought. The trade in them in the late Middle Ages was a genuine abuse — the one that helped set off the Reformation — and it was condemned not by the Church's critics but by the Church herself, at the Council of Trent, which forbade all fees connected with indulgences. Anyone offering to sell you one today is either mistaken or lying.
What the Bible Says
The LORD has put away your sin; you shall not die. Nevertheless... the child that is born to you shall die.
The clearest scriptural picture of the distinction. David's guilt is forgiven outright and immediately — and consequences remain. That gap between forgiven guilt and remaining consequence is the space an indulgence works in.
Whatever you bind on earth shall be bound in heaven, and whatever you loose on earth shall be loosed in heaven.
The authority the Church claims when she grants an indulgence. Whether that authority extends this far is exactly what the Reformation disputed; the Catholic answer is that loosing means what it says.
I rejoice in my sufferings for your sake, and in my flesh I complete what is lacking in Christ's afflictions for the sake of his body.
The idea behind the treasury of merit: that satisfaction made by one member of the body can genuinely benefit another. Not a currency, but not merely a metaphor either.
What the Catechism Says
CCC 1471An indulgence is a remission before God of the temporal punishment due to sins whose guilt has already been forgiven, which the faithful Christian who is duly disposed gains under certain prescribed conditions.
CCC 1472Sin has a double consequence. Grave sin deprives us of communion with God; every sin, even venial, entails an unhealthy attachment to creatures, which must be purified either here on earth, or after death in the state called Purgatory.
CCC 1478An indulgence is obtained through the Church who, by virtue of the power of binding and loosing granted her by Christ Jesus, intervenes in favour of individual Christians and opens for them the treasury of the merits of Christ and the saints.
CCC 1479Since the faithful departed now being purified are also members of the same communion of saints, one way we can help them is to obtain indulgences for them, so that the temporal punishments due for their sins may be remitted.
