The Wizards in the WATCH TOWER (See "Enochian Magick") get away with this because of the New World [Order] "Translation".
At Luke 22:20, they correctly rendered the Greek Word "diatheke" as "covenant". Later on in verse 29, after Judas had been dismissed, the same word "covenant" appears in the NWT, but this time the Greek word is "diatithemai". It does not mean "covenant", it means "appoint", as the KJV and almost every other translation properly renders it. Since the dubs are forbidden to do personal research they'll never get it. In the meantime, the Satanists up in the Tower get off on having 15 million people refuse the body and blood of Yeshua. They also conjure up powers from this, just like they do every time someone utters the word "Jehovah", the most important word in Freemasonry, which they use in their murder rituals.
If anyone who is interested in finding out just how Satanic the Watchtower is, and has been since its conception by Rosicrucian CT Russell, download and read "Be Wise As Serpents" by Fritz Springmeier. It is a fantastic book that you won't be able to put down.
