It seems to me when you write "Rome," blinders come down. Try instead to imagine you are a Catholic who loves the LORD, has made a perfect act of contrition, fully believes everything in the Apostle's Creed, and has entered the assembly to offer a thanksgiving sacrifice by doing whatever Jesus said to do in memory of him. Just try.
Just try to know what your church teaches.... The Church teaches that the Sacrifice of the Mass and the Sacrifice of the Cross are one and the same sacrifice. .... The mass is not a "thanksgiving" sacrifice" it is the re sacrifice of Christ where you eat the sacrificed body
The Unbloody Sacrifice by: The Rosary Team The Mass is often referred to as the Unbloody Sacrifice of Calvary. It is called such because during the Mass Jesus acts as both Victim and Sacrifice through the words and actions of the priest and is offered in an unbloody way to God the Father. This is taken directly from the Baltimore Catechism which states: " The Mass is the sacrifice of the New Law in which Christ, through the ministry of the priest, offers Himself to God in an unbloody manner under the appearances of bread and wine." The Catechism goes on to explain: "The Mass is the same sacrifice as the sacrifice of the cross because in the Mass the victim is the same, and the principal priest is the same, Jesus Christ."
The Mass is different from the Sacrifice of Calvary in the fact that Jesus is not physically crucified again because Jesus died once for the remission of sins and can die no more. The Mass simply "applies to us the merits and satisfaction of His death on the cross". (Baltimore Catechism)
Catholics MUST accept Trent
The Council of Trent infallibly decreed at Session 22: “If anyone says that in the Mass a true and proper sacrifice is not offered to God or that that which is to be offered is nothing else but what Christ has given us to eat let him be accursed” – Canon 1.
“If anyone says that the sacrifice of the Mass is merely a sacrifice of praise and thanksgiving or that it is a bare remembrance of the sacrifice completed on the cross but is not a propitiatory sacrifice or that it profits only him who receives and that it ought not to be offered on behalf of the living and the dead for sins, sufferings and satisfactions and other necessities let him be accursed” – Canon 3.
So according to Trent you would be cursed if you think it is a thanksgiving sacrifice...or a remembrance
Could you please explain this to an old, ignorant Protestant?
