You mean during the consecration, a majority of Catholic churches are speaking falsely by saying “shed for you and for all so that sins may be forgiven”? I have to shut my ears when the Mass comes on EWTN?
1 John 2:2 is utterly clear. “The whole world” is unambiguous.
Any priest who is still saying those words is a disobedient priest. And, "Yes", they are speaking falsely.
From the missalette:
“TAKE THIS ALL OF YOU, AND DRINK FROM IT, FOR THIS IS THE CHALICE OF MY BLOOD, THE BLOOD OF THE NEW AND ETERNAL COVENANT, WHICH WILL BE POURED OUT FOR YOU AND FOR MANY FOR THE FORGIVENESS OF SINS. DO THIS IS MEMORY OF ME.”
Sorry this is all in caps, but it is that way in the missalette.
The gate is open but the way is narrow.
