Gem:Praised be Jesus Christ, present with us today in the sacrifice of the Altar.
1 Peter 3:18 NASB
For Christ also died for sins once for all, the just for the unjust, so that He might bring us to God, having been put to death in the flesh, but made alive in the spirit;
Hebrews 7:26-28 NASB
For it was fitting for us to have such a high priest, holy, innocent, undefiled, separated from sinners and exalted above the heavens; who does not need daily, like those high priests, to offer up sacrifices, first for His own sins and then for the sins of the people, because this He did once for all when He offered up Himself. For the Law appoints men as high priests who are weak, but the word of the oath, which came after the Law, appoints a Son, made perfect forever.
You seem to have a problem with the “once for all” bit.
The problem is in your understanding of the misinterpretation of the scripture. yes. Jesus died once. We are at that SAME instant in time the sacrifice of the Mass is offered.
In John 6: Jesus didn’t say “Hey, folks, step right up for one time only eat my flesh and drink my blood.” NO. He meant it was on “forever” offer.
Accept no imitations. The Mass stands OUTSIDE of time.
