I said RE-presentation, not RE-sacrifice, TB.
In the Holy Mass, you are PRESENT at that VERY moment that happened on Calvary 2000 years ago.
What is happening on the altar at that moment of Consecration is not Calvary happening AGAIN, it is Calvary happening STILL.
How can this be?
Because Christ’s sacrifice is ETERNAL, — eternally PRESENT to the Father — and to you, too, at that moment of Consecration in the Holy Mass.
Eternity is a concept beyond our understanding.
It doesn’t mean “forever” nor a long period of time. It means “outside of time itself”; a perpetual present, a never-ending now. God apprehends all events in time in a single glance of “now”. The “thousand years is a single day” suggests how different the Divine Perspective is from ours.
The sacrifice of Christ is not time-bound. That’s why the institution of the Holy Eucharist was possible at the Last Supper — hours before Calvary. It anticipates the Sacrifice on Calvary, because the future is PRESENT from God’s eternal perspective. Easy-peasy for God.
The Catholic Church believes, as you do, that there is no need for a subsequent sacrifice since the first is infinitely more than sufficient in itself.
And infinitely more than we deserve.
One act of disobedience brought sin into the world and one act of obedience provided a way out. The acts of Adam's sin and Christ's crucifixion were singular events with eternal results. Wouldn't it be better to celebrate the fact that we can now approach the Throne of Grace boldly without anyone between us and God, having been clothed in the righteousness of Christ?
Jesus is currently and eternally seated at the right hand of the Father. Why does the Catholic church keep Him perpetually nailed to the cross?
