It is all a little confusing and has to do with the movable date of Easter. Rather than abandon Mass texts of the Mass, sometimes for many years between the 7th and 13th Sundays in Ordered Time as in the non-rigid modernist rite known as the Novus Ordo, the traditional calendar keeps those from the 3rd to 6th Sunday after Epiphany and moves them to this time to fill the gap. Yet, Gregorian Propers for the 3rd to 6th are the same as are those from the 22nd Sunday to the Last. More confused?
But, make no mistake. Sacrosanctam Concilium and the GIRM in the modernist, non-rigid, Missal already call for "ad orientem" worship, Gregorian chant, Latin, incense and more. No priest must be forced to use Extraordinary Ministers and people can always receive Holy Communion on the tongue and kneeling. Even with that, we know, it is still deficient. My point here is not to believe those who insist it must be "reformed" formally, or that any mandated reform closer to the traditional, is "dead." it is only dead for now.
Out of the depths I have cried to Thee O Lord! Lord, hear my voice. Let Thine ears be attentive to the voice of my supplication. If Thou, O Lord! wilt mark iniquities: Lord, who shall stand it? For with Thee there is mercy: and by reason of Thy law I have waited on Thee, O Lord!My soul hath relied on His word: my soul hath hoped in the Lord. From the morning watch even until night:let Israel hope in the Lord. For with the Lord there is mercy; and with Him plentiful Redemption. And He will redeem Israel from all his iniquities.
