Really? Wow, how'd that go?
Actually, nobody said a word. The body of elders well knew that I was questioning certain doctrines.
What I did was to read every verse in the gospels that said a word about the last supper, (without any comment at all), and then directed the MS guys to pass the bread & wine.
I did get some criticism for allowing many of the young kids to taste the bread and wine (on the platform) after the ceremony had ended.
I resigned as an elder about 4 months later and never attended another meeting past about 10 minutes at one last circuit assembly.
Like singer Tom Petty said - "I sing this victory song - I'm already gone".
