It’s called the sacrifice of the mass. In a sacrifice, something is killed for atonement. The name alone indicates that a killing takes place.
If Jesus isn’t killed then why do you call it the sacrifice of the mass?
Catholicism can play all the word games it wants, but it’s no secret that they consider it participation in His sacrifice and that can only happen when the event occurs.
They are offering Jesus up to God as a sacrifice for our sins as if He were an animal.
Your comments indicate the understanding of scripture and Catholic faith is weak.
Many repeat the anti-Catholic myths and lies.
The old testament had multiple bloody sacrifices to worship God, and the new testament had one bloody sacrifice of humble servant Christ for God the Father by doing His will on the Cross for our sins. Jesus opened Heaven to all by His death and resurrection.
Jesus established the Mass and the Sacrament of the Eucharist at the Last Supper to replace the Passover meal. The new covenant established by Jesus a non bloody sacrifice of the Mass for the glory of God the Father and the salvation of the world. We celebrate with Jesus as the High Priest through the ordained priest as we receive Jesus - Body, Blood, Soul and Divinity in the Eucharist.
You should try understand the definition of sacrifice and not make rash statements.
