Well, I have the 1970 Rite of Marriage book right in front of me.
In this book it actually includes the Penitential Rite. There’s nothing in here which says that the Penitential Rite should be omitted.
I also just found a pdf online of the Third Edition of the Roman Missal
Here the Kyrie is not mentioned. Does one assume that the Kyrie is always said regardless or is it assumed that the Kyrie is part of the Penitential Act and therefore is omitted?
The missal also lists the Kyrie as separate from the Penitential Act
For Pentcost Sunday
Baptism
Based on these, it seems that the Missal considers the Kyrie as separate from the Penitential Act.
Certainly the parts are clearly identified and the Kyrie is separate: 1) the entrance song, 2) greeting, 3) penitential rite, 4) Kyrie, 5) Gloria, and 6) opening prayer or collect.
Also you said, missing in the logic was: “If the Penitential Act and blessing/sprinkling of water are not to be done THEN?” Actually that is the ELSE case shown, but, it seems that the “programming logic” style presentation did not help, so I am abandoning it.
From Zenit, Father Edward McNamara, professor of liturgy at the Regina Apostolorum university states, referring to Introduction to the Divine Office No. 94, that "This norm allows for both " and also that “… the Kyrie would normally be omitted whenever the rubrics for a blessing indicate the omission of the penitential rite.”
Introduction to the Divine Office No. 94:The psalmody of morning prayer follows as usual, up to, but excluding, the reading. After the psalmody the penitential rite is omitted and, as circumstances suggest, the Kyrie; the Gloria then follows, if required by the rubrics, and the celebrant says the opening prayer of the Mass. The liturgy of the word follows as usual.
Notice that when the sprinkling occurs in place of the usual Penitential Act it does not include the Kyrie.
There are times that the Kyrie is
always omitted:
- At Sunday Masses at which the Sprinkling Rite takes place
- At the Easter Vigil
- At the ritual Mass for the conferral of baptism
- At the funeral Mass after the remains of the deceased have been sprinkled
There are times when the Kyrie is omitted
if appropriate:
- At the Pentecost Vigil
- At a stational Mass in Lent
- At the Palm Sunday Mass following the procession or solemn entrance
Note that the Penitential Act is omitted for at least these:
- Ash Wednesday
- Palm Sunday
- Presentation of the Lord
- when baptism of children occurs during Sunday Mass
- when annointing of the sick occurs during Sunday Mass
- the consecration or blessing of a church
- the blessing of a new presidential chair
- when lauds or vespers are joined to Mass
Also it is an option to omit the Penitential Act at children’s Masses.
