The JDubs go through a lot of effort to secretly put a Memorial invitation in every door in their territory to invite strangers to celebrate that Jesus died only to be told while at the Memorial that they can't nibble or sip the emblems even though Jesus said that they should. Maybe Jesus words, "Keep doing this in remembrance of me," is just a little too difficult to understand.
These people will be surprised to learn that they aren't qualified, worthy, or deserving to partake. They can however fully reject the blood and body of Jesus by passing the emblems on to the next person.
I wonder how Jesus feels every year when millions of people in the Kindom Hauls turn up their noses at him?
