Does faithful and devout attendance at Sunday Mass absolve your venial sins without the Sacrament of Reconciliation? That is, as you attend, are your venial sins forgiven right then?
The absolution given in the penitential right of the Mass can absolve venial sins. Venial sins do not require sacramental absolution. Actually, just an act of contrition is sufficient.
