More to the point Hebrews 10:8-14, especially verse 10:
"... we are sanctified through the offering of the body of Jesus Christ once for all."
Here, "once" is εφαπαξ, which is a strengthened form of απαξ that means "once for all time, never to be repeated" -- which the context fully supports, so that it cannot be argued that the sacrifice continued. Jesus came to fulfill The Law, and on the Cross He cried out the victory proclamation "τετελησται" -- "FINISHED!" (Jn. 19:30)
I believe that it is a crime to keep on insisting, that what was then and there finished, is still going on. He left the cross, revived, entered into The True Holiest Of All In Heaven, and displayed His Incorruptible Life-bearing Blood on the Mercy Seat, obtaining propitiation and reconciliation by ONCE satisfying all of The God's righteous demands for ever, making it a surety for us, who have come to persistently commit trust in Him, to belong to The God without recrimination, remorse, nor reversal.
The Remembrance Supper is a memorial of His Cross-death, in which His regenerated believer-disciple-priests partake of the Tokens of His Passion, lest we forget.
And what crime, in particular, do you believe it to be.
As I said, the problem is that thinking that "eternal" means "still going on." It doesn't.
