Q: In the case of lauds or vespers joined to Mass, since the psalmody replaces the penitential act, is it necessary for the priest, at the end of the psalmody to recite the absolution like during the Mass: “May almighty God have mercy on us, forgive us our sins, and bring us to everlasting life”?
==
A: No, that absolution is part of the penitential act that is omitted.
