The Precious Blood of Jesus is in all the sacraments. Father Faber
My great-great uncle was Fr. Rudolph Stoltz, of the Confraternity of the Precious Blood in Carthagena Ohio ordained in 1907. Their mission was to speak of the Powers of the Precious Blood. When Christ died, the demons were just then in understanding that the Blood was saving, Powerful! They screamed and ran back to hell. One time I mentioned the Beauty of the Precious Blood of Christ and this man got mad! IMO, he had a devil harbored and he had to tell me , sorry, like when someone burps and has no control.
That is why I think this aspiration is powerful to scare demons off and it also makes it very clear for you knowing your sins are forgiven.
