"No! the chastisements of God are not yet at an end; still more sorrowful times are ahead; and divine justice will be placated by the devotion to the Blood of Jesus Christ."  Extract from a homily by Saint Gaspar del Bufalo

Prior to Gaspar's time, devotion to the Precious Blood had been restricted to a select few. Many Catholics, including some members of the hierarchy, shuddered to think of the sacred term being bandied about on the lips of all; rather they thought it should receive the extreme reverence reserved for the name of God in the Old Testament. Gaspar, however, longed to make the devotion "one that was broad and social enough to challenge all mankind."

He wrote:  "In every era the Lord has inspired certain devotions to stem the tide of iniquity. We also see that in times past the Church was attacked in this or that doctrine. Today the war is being waged against religion as such and against Christ Crucified. We need, therefore, to reemphasize the glories of the Cross and of our Crucified Redeemer, to reopen the fountains of mercy just when the devil would make us the victim of wrath. Now, more than ever, it is opportune to tell people at what price our souls were redeemed. We must let it be known how the Blood of Christ cleanses the souls and sanctifies them, particularly by means of the sacraments. We must arouse them from their insensibility by reminding them that His Blood is offered up every morning upon the altars and that instead of blasphemy and insult, we should give it adoration and praise."

This litany clearly traces the line of salvation history through a series of biblical references and passages.  A partial Indulgence is granted to the faithful who recite this litany.
