So let me see if I get your point here. God’s Eternal vantagepoint of the Universe is *not really applicable to the issue*?
Funny, I’d think it was more applicable to the issue than our own.
Is it true, or is it not true, that Calvary, like every other moment in time, is eternally present to God the Father who lives in the Eternal Now?
I don't think so...I see that as a philosophical (wisdom of man) attempt at an explanation for things of God that are not understood in the spiritual realm...
At one time I bought my first car...Past tense...I can tune into my conscience and see myself buying that car right now...But guess what, I am not buying my first car today, and tomorrow or the next day...God has given us no indication he see anything any differently...
Gen 1:1 In the beginning God created the heaven and the earth.
When was 'in the beginning'??? Does it say that God is creating the earth???
The creation is past tense...God certainly knows that...It's done with...It's finished...Just as God knows the sacrifice of his Son is past tense...It is finished...
Eternally known or present does not mean eternally ongoing.
But what's being discussed is not God's vantage point.
It's the claim that the Catholic church is participating in the death of Jesus every time they perform the mass. It can't be because that happened 2,000 years ago and while God is transcendent in regard to time, we're not.
And even if God *sees* all time as presence before Him, does not go to follow that it is reality happening for eternity in heaven.
Indeed, as is the creation of the word and the final judgment, but God deals with us in time and space, and thus Christ came in the fulness of time, and once offered Himself for our sins, and sat down.
You simply cannot make Him to be offering the same sacrifice again and again any more than creating the universe again again. Thus your argumentation is absurd.
