Litany for Priests

Jesus, meek and humble of heart, give all priests Thy spirit of humility; Jesus, poor and worn out for souls, give all priests Thy spirit of zeal; Jesus, full of patience and mercy for sinners, give all priests Thy spirit of compassion; Jesus, victim for the sins of the world, give all priests Thy spirit of sacrifice; Jesus, lover of the little and the poor, give all priests Thy spirit of charity. Mary, Queen of the Clergy, pray for us; and obtain for us numerous and holy priests and religious. Amen.
