A false characterization of Catholic doctrine. You would be much better off asking us what we believe rather than telling us. It might save you some embarrassment.
Based on what O'Brien has written.....I can tell you what is happening during the Mass. You may not believe it, but you're not a RC priest so you really have no authority on the issue as a Roman Catholic.
Which you persist in misunderstanding. Are you claiming Protestants are sacrificing Him "over and over and over"?
I can tell you what is happening during the Mass.
Apparently, you can't. Catholics don't keep Him nailed to the cross any more than Protestants, who believe the Eucharist "is the true body and blood of our Lord Jesus Christ”. Are you accusing Protestants of keeping Him nailed to the cross? Do you believe in His real presence in the Eucharist as do Protestants?

I have more authority on understanding Catholic doctrine than do you.
