Luke 22: 20 Also, he did the same with the cup after they had the evening meal, saying: " this cup means the NEW COVENANT by virtue of my blood, which is to be poured out in your behalf." WT 14 10/15 14 says: The new covenant creates the spiritual Israel, and it is the legal basis for the anointed ones to become joint heirs with Christ.
Excuse me, but that isn't what Jesus said the new covenant was about. It is for forgiveness of sins for the many. Cross reference New covenant, and it is about Jesus sacrifice for forgiveness of sin.
The scriptures about the bread and wine are read every year and because of the pre programmed group think, the rank and file aren't getting the truth of what they are reading.
