The Prayer to Be Said at the Time of the Holy Mass

Eternal Father, I offer to Thee the sacrifice which Thy beloved Son Jesus made of Himself upon the Cross, and now renews upon this altar; and I offer it to Thee in the name of all creatures, together with the Masses which have been celebrated, and which shall be celebrated, in the whole world, in order to adore Thee, and to give Thee the honour which Thou dost deserve; to render to Thee due thanks for Thy innumerable benefits, to appease Thy anger for our sins, and to give Thee due satisfaction for them; to entreat Thee also for myself, for the Church, for the whole world, and for the blessed souls in purgatory. Amen.
