“I am planning to start off with John 6:54 where Jesus says that everyone should partake in the Emblems. Then I plan to move on to Blood Issues, UNO, and those whole bunches of WT non senses and Flip Flops.”
Stick to one topic...the first one as you state should be answered. Along with this one...show me in the scriptures where jesus said to go out and invite anyone else to observe the ones he instructed to observe the memorial?
As for me if they can show me in the scriptures where Jesus invited or said to invite any non believers or those not of the anointed class to observe...then I would consider going!
