The term used in the original text of the Roman Missal (in Latin) is Actus Paenitentialis. In the English translation of the Roman Missal used from 1973 to 2011, it was called the Penitential Rite.
In the Order of Mass of the Roman Rite, which is the most widespread liturgical rite in the Catholic Church, the introductory part of Mass normally includes a Penitential Act after the making of the sign of the cross and the priest's greeting.  The Roman Missal provides three forms. The priest begins each with an exhortation to acknowledge one's sinfulness as preparation for celebrating the sacred mysteries and he ends it with the prayer, "May almighty God have mercy on us, forgive us our sins, and bring us to everlasting life", a deprecatory absolution, as distinct from the declarative or indicative absolution, "I absolve you from your sins". Between these two interventions by the priest, sinfulness is acknowledged in one of three ways;
- Recitation of the Confiteor;
- A short prayer, beginning with "Have mercy on us, O Lord", recited alternately by priest and people;
- A short litany spoken or sung, not necessarily by the priest, to each of whose three variable invocations or tropes the people respond with the acclamation Kyrie, eleison or Christe, eleison (Lord, have mercy; Christ, have mercy)
If certain celebrations are combined with Mass, then the Penitential Act and other parts of the Introductory Rites are omitted or performed in a different way. An example is the Mass of Ash Wednesday, in which the Penitential Act is replaced by the blessing and imposition of ashes after the homily.
The priest says:
- Misereátur tui omnípotens Deus, et dimíssis peccátis tuis, perdúcat te ad vitam ætérnam (May Almighty God have mercy on you, forgive you your sins and bring you to everlasting life).
The Confiteor is then repeated by the others, replacing vobis fratres and vos fratres (you, brethren) with tibi pater and te pater (you, Father). The priest responds with the Misereatur is spoken by the priest replacing tui with vestri, tuis with vestris, and te with vos. The priest responds with two prayers: Misereátur vestri omnípotens Deus, et dimíssis peccátis vestris, perdúcat vos ad vitam ætérnam (May Almighty God have mercy on you, forgive you your sins and bring you to everlasting life) and (making the sign of the cross) Indulgéntiam, absolutiónem, et remissiónem peccatórum nostrórum, tríbuat nobis omnípotens et miséricors Dóminus (May the Almighty and Merciful Lord grant us pardon, absolution, and remission of our sins).
In the original Tridentine Roman Missal (1570), the Misereatur prayer added the adjective omnibus ("all") to the phrase dimissis peccatis tuis/vestris ("forgive you [all] your sins").
Usage in Lutheranism
What is sometimes known as "general confession" takes place at the start of Lutheran Divine Service. The pastor and congregation say a Confiteor and the pastor says the Declaration of Grace. The Declaration of Grace is not an absolution. In Lutheran practice, the sacramental rite of confession is its own separate service, and private confession is expected before partaking of the Eucharist.
Pastor: "If we say we have no sin, we deceive ourselves, and the truth is not in us."
People: "But if we confess our sins, God who is faithful and just will forgive our sins and cleanse us from all unrighteousness."
Pastor: "Let us then confess our sins to God our Father."
People: "Most merciful God, we confess that we are by nature sinful and unclean. We have sinned against you in thought, word, and deed, by what we have done and by what we have left undone. We have not loved You with our whole heart; we have not loved our neighbors as ourselves. We justly deserve Your present and eternal punishment. For the sake of Your Son, Jesus Christ, have mercy on us. Forgive us, renew us, and lead us, so that we may delight in Your will and walk in Your ways to the glory of your Holy Name. Amen."
Pastor: "In the mercy of almighty God, Jesus Christ was given to die for us, and for His sake God forgives us all our sins. To those who believe in Jesus Christ He gives the power to become the children of God and bestows on them the Holy Spirit. May the Lord, who has begun this good work in us, bring it to completion in the day of our Lord Jesus Christ."
