Jesus, who from the tenderness of your divine heart, uttered prayers of compassion for poor humanity, seeking a guide that might conduct it along the difficult paths of the world towards the light and the life; O Lord, who made messengers of Your angels and flaming fires of Your servants, send to these people who are Yours, and who wish to be Yours, many priests, and clothe them with holiness so that Your saints may rejoice.
[from Mediator Dei]
