…“pure offering” is meant offerings which do not have defilements, i.e., animal sacrifices."
I take this to mean that all animals are defiled and therefore they cannot be a “pure offering”.
But this would nullify what was said in the Old Testament when Moses directed the people to take a lamb, which was unblemished and in perfect condition, and sprinkle it’s blood above their doors, and was to be eaten in a meal that night. So according to this there is such a thing as an unblemished, spotless lamb or animal.
John the Baptist calls Jesus the real Lamb of God, who indeed was unblemished and pure, to take away the sins of the world.
The Old Testament lamb is a figure of the New Testament which would spare the people death(eternal) as the Old Testament lamb spared the people death(first born). IN both cases, unblemished, sacrificed, and eaten for the purpose of propitiation, the means by which the people are to be spared death. In both cases it was the lamb’s blood … propitiation.
Since the Mass is the sacrifice of Jesus, who was spotless, brought forward in time to us making the Mass the same sacrifice now as it was then, making the Mass as sacrificially powerful as it was then, making the Mass as much a propitiation now as it was then…because in reality it is one and the same.
As far as scriptural quotes go, there are plenty to define the sacrifice of Jesus as propitiatory.
"…who in His blood has reconciled us with God made unto to us justice and sanctification and redemption. I Cor.1,30
“The slavery from which Christ purchased mankind throught his sacrificial death is the slavery of sin.” Tit 2,14
And Isaiah chapter 53.
And I wouldn’t think anyone would deny that Jesus was spotless and pure. So when Malachi says “Incense offerings are made to my name everywhere, and a pure offering;” it would mean that a pure offering would be made everywhere on earth which describes the Mass perfectly as Jesus is the pure victim.
Malachi is saying that incense offerings and also a pure offering, so I don’t see this as "incense offerings, which are pure offerings. Incense offerings is plural, in contrast to pure offering which is singular. So the conclusion is that the last offering does not refer to the first offerings, but rather both are separate and are pointed out.
The Mass describes this perfectly, namely, praise(incense) and propitiatory(pure victim).
