Sayitsnotso,
If the org made 144,000 symbolic they would solve many issues such as the increased nuber, and if they continued to stress 'great crowd' and earthly hope' they'd be fine so far as that. However, if the members all claimed to be annointed they'd have issues since they teach the 'annointed' will reign from heaven over the earthly crowd. Mainstream Christianity does not teach 2 groups in 2 locations. The org would then have to answer who the one class is ruling over. If they were to go mainstream and teach that there is one class which will rule from the earth over those not destroyed at armageddon who have not made a choice either way, or those who died ignorant of the WT message...then they would have admit Jesus having a physical 2nd return. It would not make sense to have a group of non-beleivers who need to be taught alone on earth submitting to heavenly rule.
