i pointed out in another post that some days i feel like i should take the emblems (other days my faith is gone entirely and i would say im agnostic).
i just wanted to point out that not all who take the emblems have mental or emotional problems. of course some are but not all! quite a few just have their own private view (of course they cant go round saying it or will be dfd) that all christians should take the emblems. they are not in a separate higher category. they simply want to obey jesus and see no scriptural reason not to take them.
it may be that some take them privately after the memorial so as not to make a scene (i considered it this year but chickened out), so those who do so openly may by definition have some form of mental problem as they are willing be seen as crazy by others and dont care!
i think the day will come that the society will change the thought on taking the emblems. they wont get rid of the earthly group immediately, as that is too big a change, but they will say all are one flock, all are in the new covenant and all should take the emblems. the dubs will love this, and completely forget that for decades they have been refusing jesus' blood each year!
