Try putting on your thinking cap. IF He died onto sin ONCE and only once then how much sin did He die for that once?? It HAD to be ALL sin. ONCE. Otherwise He would have to die over and over, every time sins are committed. That would make Paul a liar. He said He died unto sin ONCE.
Oh but wait. The RCC is making him a sacrifice at every mass. Over and over again. Not once.

As far as your reliance on St. Paul:
[6] For which things the wrath of God cometh upon the children of unbelief, [7] In which you also walked some time, when you lived in them. [8] But now put you also all away: anger, indignation, malice, blasphemy, filthy speech out of your mouth.
Epistle of St Paul to the Colossians, Chapter 3
