I have here a copy of Fr. Laux's Mass and the Sacraments, from 1928, ed.
In Chapter IV, The Holy Eucharist, on p. 80:
"The words of Consecration, with those that immediately precede them, do not
exactly correspond to the Scriptural narrative, although the sense is absolutely
the same. Perhaps our present text goes back to a time before there was any
There is a footnote by the editor (probably Thomas A. Nelson) on p. 196 that says,
"There is a tradition in the Roman Catholic Church that the words of Consecration
used in the Traditional Mass of the Roman Rite are the exact words used by Our
Lord after the Last Supper."
This touches on the infallibility of Sacred Tradition, and its vast importance for the
Remember that Jesus spent 40 days after His Resurrection with the Apostles,
and during that time, He no doubt taught them necessary details, not the least
of which would have been to say Mass every day, and then by giving them
this example, He would have shown them HOW to say Mass. He would have
been right there to gently correct them if they got something wrong by mistake.
Remember that Sacred Tradition holds equal authority with Sacred Scripture in
the Catholic Church, and that this is the principle disagreement that Protestants
have with the Church. In fact, Tradition is the SOURCE of Scripture, for without
Tradition we would not know what is Scripture and what is not Scripture. So
along come the Protestants and they denied Tradition, but proceeded immediately
to set up their OWN tradition of REMOVING certain parts of the Bible, claiming
that they are now the authority for what is NOT Scripture.
In the end, if we just stop the nonsense of having Mass prayers in vernacular
languages, we wouldn't have this problem. The Latin Rite should be in Latin.
