The problem then becomes that it's not the mass that causes the change but the faith of the person who believes that the change is happening.
If the change in the bread and the wine is as Catholics say, then it happens because it happens, independent of which setting it's in, which church.
It's going to happen independent of the faith of the people around because it would be a truth that stands independent of man, as the truths of Scripture are.
If the non-Catholic interpretation is correct, that the elements are simply bread and wine REPRESENTING Christ's body and blood, then all the hand waving and muttering of any priest is NOT going to change that.
So in essence, the Catholic ritual of the mass is not needed.
You are really bad a logic aren’t you?
Strange how my question also never gets answered.
