27. At the invitation of the deacon or other minister, all kneel or bow down and say a form of general confession (for example, the prayer, I confess to almighty God). Then they stand, if this seems useful, and join in a litany or suitable song to express confession of sins, heartfelt contrition, prayer for forgiveness, and trust in God’s mercy. Finally, they say the Lord’s Prayer, which is never omitted.
A litany of forgiveness may be proclaimed together. I’m assuming that a deacon or cantor would lead this. A hymn is also suggested. I have to confess my surprise that psalmody is not considered here, especially one of the penitential psalms. Note that the Lord’s Prayer preceding the individual confessions is never omitted … if you’re going “by the book.”
28. After the Lord’s Prayer the priests go to the places assigned for confession. The penitents who desire to confess their sins go to the priest of their choice. After they have accepted a suitable act of penance, the priest absolves them, using the formulary for the reconciliation of an individual penitent.
The rite presumes that not everyone participating might want to confess sins, and perhaps some others in the community would attend to develop a sense of penitence, or even pray for the community’s penitents.
29. When the confessions are over, the priests return to the sanctuary. The priest who presides invites all to make an act of thanksgiving to praise God for his mercy. This may be done in a psalm or hymn or litany. Finally, the priest concludes the celebration with one of the prayers in praise of God for this great love.
Here at the end there is a choice of psalm for the act of thanksgiving and praise of the assembly.
DISMISSAL OF THE PEOPLE
30. After the prayer of thanksgiving the priest blesses the faithful. Then the deacon or the priest himself dismisses the congregation.
Note no closing song or hymn–just like at Mass. I don’t know many parishes that actively encourage beginning to end attendance. Many pastors expect departures after the individual confessions. Another poverty, imo.
