In Missis Defunctorum, et in Missis de Tempore a Dominica Passionis usque ad Sabbatum sanctum exclusive, omittitur Psalmus Iúdica me, Deus, cum Glória Patri, et repetitione Antiphonæ, sed dicto In nómine Patris, Introíbo, et Adiutórium, fit conféssio.
This part is left out at Requiem Masses and from Passion Sunday to Holy Saturday. What goes is the psalm together with the Glória Patri and the repetition of the antiphon; the rest of the prayers at the foot stay — the sign of the cross, the antiphon and the Adiutórium — and the confession follows at once.
Postea alternatim cum Ministris dicit sequentem:
The priest says the psalm alternately with the server, verse for verse. At a dialogue Mass the faithful answer with the server.

Sacerdos repetit Antiphonam:
The psalm ended, the priest takes up the antiphon once more — as in the Office an antiphon returns after the psalm it framed.
