I may have gotten the texts mixed up (I don’t have my missal with me at work; there are several invocations to this version), but, I think you get the general idea. When this formula is used (option 3), then you don’t need the Confiteor nor the extra Kyrie.
Just to clear things up…
The Sacramentary lists three forms (A, B, and C) for the Penitential Rite.
Form A is the
Confiteor: I confess, to Almighty God, and to you my brothers and sisters…
Form B is a brief call-and-response:Lord, we have sinned against you:
Lord, have mercy.
Lord, have mercy.
Lord, show us your mercy and love.
And grant us your salvation.
Form C is a set of three invocations (such as the following, but there are at least a dozen versions provided in the Sacramentary):Lord Jesus, you were sent to heal the contrite: Lord, have mercy.
Lord, have mercy.
Lord Jesus, you are Son of God and Son of Mary: Christ, have mercy.
Christ, have mercy.
Lord Jesus, you are the Way that leads to the Father: Lord, have mercy.
Lord, have mercy.
After the Penitential Rite, the
Kyrie is then invoked,
unless it has already been used in the Penitential Rite. The
Kyrie, properly, is:Kyrie eleison.
Kyrie eleison.
Christe eleison.
Christe eleison.
Kyrie eleison.
Kyrie eleison.
It is often said in the vernacular (Lord, have mercy; Christ, have mercy; Lord, have mercy).
My impression is that only Form C of the Penitential Rite contains the
Kyrie; thus, it is required after Form A (the
Confiteor) and Form B (which I don’t know a “name” for). Seeing as how the Pope had the
Kyrie invoked by the choir after Form B, I would guess I am correct in that regard. Furthermore, to use multiple forms of the Penitential Rite (such as Form A followed by Form C) is incorrect; the
Confiteor (Form A) must be followed by the
Kyrie,
not by Form C of the Penitential Rite.
