Part of the Canon of the Mass, said by the celebrant just after the First Intercession and just before the Pre-Consecration Epiclesis ("Vouchsafe...")
All servers should be kneeling during the Hanc Igitur. The acolyte is standing and pointing the missal for the celebrant.
WE beseech thee then, O Lord, graciously to accept this oblation from us thy servants, and from thy whole family; order thou our days in thy peace, and bid us to be delivered from eternal damnation, and to be numbered in the fold of thine elect.
The Hanc Igitur has a special form for the Easter Octave
On the Easter Vigil and throughout the Easter Octave
We beseech thee then, O Lord, graciously to accept this oblation from us thy servants, and from thy whole family; we present it unto thee on behalf also of those whom thou hast vouchsafed to regenerate by water and the Holy Spirit, granting unto them remission of all their sins; order thou our days in thy peace, and bid us to be delivered from eternal damnation, and to be numbered in the fold of thine elect.
