In this divine sacrifice...that same Christ is contained and immolated in an unbloody manner who once offered himself in a bloody manner on the altar of the cross...This sacrifice is truly propitiatory..

Without the shedding of blood, there is no remission of sins.

And unbloody sacrifice is useless killing.

The life is in the blood. So without blood, there is no life. “For the life of the flesh is in the blood..:(Lev. 17:11). If it is an unbloody sacrifice, then no blood is there to give life..

[Campion]

Without the shedding of blood, there is no remission of sins.

Since the Eucharist is one and the same sacrifice as Calvary, there would seem to be no problem.

And unbloody sacrifice is useless killing.

??? So when the Israelites offered a grain offering -- an unbloody sacrifice -- was that "useless killing"? When Melchizedek -- a priest of God most high -- offered bread and wine, was that "useless killing"?
