The Mass is a contradiction in terms.
It does however refer to, and make present to us, Christ's death as the ultimate Sacrificial Lamb on the Cross, which certainly was immolation in the fullest, bleedingest,most agonizing sense of the word. However, what happens in the Mass is that same sacrifice, His Body, Blood, Soul and Divinity, offered the the Father for the salvation of the world, but without Christ dying AGAIN.
Trent, and other sources, IIRC, calls what happens at the "Mass" as being the same sacrifice as the Cross...except without blood....daily....hourly....over and over and over again.
At one time you disagreed with that it was done at the command of a priest over and over again. At least that is why I think you were attempting to dismiss O'Brien. But I think I've illustrated that is indeed what is happening.
In either case, the whole thing is against Scripture.
Jesus is not commanded by priests.
The priests do not become Jesus.
There is NOTHING in Scripture to support any of it....maybe other than the names being used.
BTW....there's more I haven't posted yet. Still doing more reading.
It amazes me just how wrong Rome is on this issue...among others.
Of course there is BLOOD involved in the Sacrifice of the Mass. Everyone knows that. We receive His Body and Blood.
What there is not, is repeated, redundant dying.
Once dead and risen, Christ cannot die again.
I don't know how I could make that any plainer.
