When going to Confession according the Traditional Roman Ritual the penitent enters the confessional. The priest may greet the penitent by saying:
The Lord be in your heart so that you may humbly confess your sins in the Name of the Father and the Son and the Holy Ghost. Amen
Just as in the celebration of the Rite of Penance in the Ordinary Form, in the Extraoridanry Form, the penitent asks the priest’s blessing and informs him of his state in life. The penitent indicates whether or not he has performed the penance assigned in his previous confession, and lastly, the penitent states how long it has been since his last confession. These things being done, the penitent then confesses all mortal sins according to number and kind committed since the last good confession. Venial sins, of course, may be mentioned as well.
The priest, when it is suitable, will ask questions or give counsel. A penance is assigned. The penitent recites an act of contrition. Then the priest says the absolution. The absolution must be said in Latin.
MIsereatur tui omnipotens Deus, et dimissis peccatis tuis, perducat te ad vitam AEternam. Amen.
May almighty God have mercy on you, forgive you your sins, and lead you to everlasting life. R.: Amen.
Next he raises the right hand toward the penitent and says:
INdulgentiam, absolutionem, et remissionem peccatorum tuorum tribuat tibi omnipotens et misericors Dominus. Amen.
May the almighty and merciful Lord grant you pardon, absolution, + and remission of your sins. R.: Amen.
Form for Absolution
Dominus noster Jesus Christus te absolvat: et ego auctoritate ipsìus te absolvo ab omni vinculo excommunicationis, (suspensionis), et interdicti, in quantum possum, et tu indiges. Deinde ego te absolvo a peccatis tuis, in nomine Patris, et Filii, + et Spiritus Sancti. Amen.
May our Lord Jesus Christ absolve you. And I by His authority release you from every bond of excommunication (suspension) and interdict, in so far as I am empowered and you have need. And now I absolve you from your sins; in the name of the Father, and of the Son, + and of the Holy Spirit. R.: Amen.
After the absolution the priest may add (in Latin or the vernacular), if time permits:
It is more usual to say this prayer in the vernacular.
Passio Domini nostri Jesu Christi, merita beatæ Mariæ Virginis, et omnium Sanctorum, quidquid boni feceris, et mali sustinueris, sint tibi in remissionem peccatorum, augmentum gratiæ, et præmium vitæ æternæ. Amen.
May the passion of our Lord Jesus Christ, the merits of the Blessed Virgin Mary, and all the saints, whatever good you have done, and whatever evil you have endured, achieve for you the forgiveness of your sins, an increase of grace and the reward to eternal life. Amen.
