Because Our Lord did not add those words to the prayer as He taught it There is nothing wrong with the words in themselves. In fact, they are very beautiful. But they are not Sacred Scripture. Some early Catholic copyists wrote those words in a margin; later copyists mistakenly transcribed them into the text; and the Protestant translators made use of a copy of the New Testament with the words thus included. All scholars to-day admit the words to be an interpolation. We Catholics do not use them.
