“Nor did he enter heaven to offer himself again and again, the way the high priest enters the Most Holy Place every year with blood that is not his own.” – Hebrews 9:25 NIV

This isn’t much of a teaching thing as much as a confusion of mine. I was just looking at catholic doctrine of how they view this passage in accordance to mass. They view themselves as not sacrificing Christ over and over but that his one sacrifice “re-presents” itself whenever they do mass. It’s hard to understand how they can justify that in good conscience with this passage.
