O Lord, with suppliant humility we entreat Thee, that in Thy boundless mercy Thou wouldst grant the most Holy Roman Church a Pontiff, who, by his zeal for us, may be pleasing to Thee, and by his good government may ever be honored by Thy people for the glory of Thy Name. Through our Lord, Jesus Christ, Thy Son, who liveth and reigneth with Thee in the unity of the Holy Ghost, one God, forever and ever. Amen.

That he might become a merciful and faithful high priest with God.
