TD great summary, so,
what prevents future members of the great crowd, slated to be in the courtyard of the temple, from also being in overlapping groups, if the the anointed remnant, future king priests destined for the most holy , are said to be in that questionable configuration now? wt could say:
The anointed (peter paul and mary) are assembling in heaven since 1918, prospective "0ther Sheep" potentially since 1935. --- no 1914 there!.
