Where do I find this “re-presenting” in Scripture? And just how do you define this “re-presenting” if that is what is being done?
You wrote:
“What error? Paul didn’t say Christ offered his sacrifice once in heaven? Jesus didn’t say, ‘Do this in remembrance’?”
The sacrifice is always offered in heaven. This is symbolized here on earth by the fact that there were altar railings to show what happened on the altar was happening in heaven. It is a timeless, once-for-all sacrifice that is re-presented.
“Where do I find this “re-presenting” in Scripture?”
Everywhere you find the breaking of bread after the Last Supper.
“And just how do you define this “re-presenting” if that is what is being done?”
I don’t define it. The Church does.
