Perhaps my terminology is incorrect. Three or four times a year, my Parish has what i’ve always called communal penance. The priest goes through an examination of conscience, tells everyone what penance should be preformed, and we’re resolved of our sins. I know multiple parishes in my Archdiocese that do this so I hope someone knows what I mean.
Canon Law of the Latin Rite Catholic Church
Can. 961 ß1 General absolution, without prior individual confession, cannot be given to a number of penitents together, unless:
1ƒ danger of death threatens and there is not time for the priest or priests to hear the confessions of the individual penitents;
2ƒ there exists a grave necessity, that is, given the number of penitents, there are not enough confessors available properly to hear the individual confessions within an appropriate time, so that without fault of their own the penitents are deprived of the sacramental grace or of holy communion for a lengthy period of time. A sufficient necessity is not, however, considered to exist when confessors cannot be available merely because of a great gathering of penitents, such as can occur on some major feast day or pilgrimage.
ß2 It is for the diocesan Bishop to judge whether the conditions required in ß1, n. 2 are present; mindful of the criteria agreed with the other members of the Episcopal Conference, he can determine the cases of such necessity.

In my diocese, if a parish holds a communal penance service, priests from other parishes are invited so that each and every penitent has the opportunity for private confession. Gereral absolution is never given.
