text: In the Penitential Rites imposed upon Catholics in 2011, they are to confess their "most grievous fault."  What are they confessing---that they have sinned mortally?  If they have---they need to go to Confession.  If they haven't---why do they have to say "through my  fault, through my fault, through my most grievous fault?  The liturgy of 1999 had the people acknowledge that they are sinners, without stating that they have sinned mortally.  Everyone attending Mass, either daily or on week-ends only----is not committing grievous faults [another word for sins].
