What part of the Catholic church are you a part of?
I ask because I take the Council of Trent very seriously. So seriously that I went from a Novus Ordo at about age 20 to the SSPX, then from there to a Protestant church.
In other words, if Trent is correct, then the Mass is a sacrifice. I do disagree with Trent, which is why I left, respectfully.
The Council of Trent on the Mass
"Canons On The Sacrifice Of The Mass
Canon 1. If anyone says that in the mass a true and real sacrifice is not offered to God; or that to be offered is nothing else than that Christ is given to us to eat, let him be anathema.
Canon 2. If anyone says that by those words, [21] Christ did not institute the Apostles priests;[22] or did not ordain that they and other priests should offer His own body and blood, let him be anathema.
Canon 3. If anyone says that the sacrifice of the mass is one only of praise and thanksgiving; or that it is a mere commemoration of the sacrifice consummated on the cross but not a propitiatory one;[23] or that it profits him only who receives, and ought not to be offered for the living and the dead, for sins, punishments, satisfactions, and other necessities, let him be anathema."
Your question seems to suppose that I might deny that the Catholic Mass is a sacrifice, which is odd, since I referred to it as “the Holy Sacrifice,” which is the “Kingdom of Heaven” made “manifest.”
What I said is that the sacrifice is not re-crucifying Christ over again. The sacrifice which it is, is the one, eternal sacrifice, which exists throughout time, and in every mass and every tabernacle in the world. It was completed in 30 AD, but it did not cease to exist at its completion, as temporal acts do.
If one asserts that the Holy Sacrifice was “once, and for all,” and it no longer existed after 30 AD, then what is the sacrifice of the lamb in Revelations? With what blood are people washed in?
