There are two options:
Remember your mercies, O Lord, and with your eternal protection sanctify your servants, for whom Christ your Son, by the shedding of his Blood, established the Paschal Mystery. Who lives and reigns for ever and ever. Amen.
Or: O God, who by the Passion of Christ your Son, our Lord, abolished the death inherited from ancient sin by every succeeding generation, grant that just as, being conformed to him, we have borne by the law of nature the image of the man of earth, so by the sanctification of grace we may bear the image of the Man of heaven. Through Christ our Lord. Amen.
