If Jesus is being sacrificed again, I take issue with this as an emphasis in need of reform.

"He has no need, as did the high priests, to offer sacrifice day after day, first for his own sins and then for those of the people; he did that once for all when he offered himself." 
-Hebrews 7:27

Catholic theology fully encompasses Hebrews' understanding, with repeated celebrations as a participation in the sacrifice of Christ, not as additional sacrifices.
