Further to this, what is the point of the Mass? Do we gather each Sunday or during the week to merely remember the Last Supper and the Sacrifice of the Cross. Or, do we gather in Church each Sunday to avail ourselves of the merits of Our Lord's bloody self-sacrifice upon the Cross at the real yet unbloody re-presentation of that Sacrifice upon the altar for the forgiveness of sins?
I may be wrong but I can't help but suspect that most modern Catholics have no idea of what is happening upon the altar, especially during a Novus Ordo Mass.
