Penitential Act

The Penitential Act, also known as A "Brief Order of Confession", takes place at the start of Lutheran Divine Service, and may include an Absolution, giving it sacramental weight.

[5] 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.

"[7] The Tridentine Roman Missal (editions from 1570 to 1962), which does not use the term "Penitential Act", has an equivalent, within the Prayers at the Foot of the Altar, in the Confiteor: The priest says:

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").

[1] As in the Roman Rite, a Thanksgiving for Baptism (similar to the Blessing and Sprinkling of Water) may replace the brief order of confession.
