 So in the Roman Catholic Latin rite, the introductory rite, we have the entrance song and then the act of penitence. So is this essentially the same? Similar. The penitential rite we'll have a little bit later, but this in some way is a biblical allude to the fact that Christ said, like, if you before come into the altar of the Lord, you have to reconcile with your brother. So this is a, maybe the beginnings of penance, beginnings of rite.
