Eyeuse2badub, blondi, thank you for touching that issue.
Is it not true, that at Catholic Mass and protestant services not everyone partakes? so, by itself having observers only is not unusual. What makes wt unique is, that they proscribe baptised and confirmed members from partaking. happens among Catholics only to the excommunicated.
Wt treats the "Other Sheep" like main stream Christianity deals with the excommunicated.
