I think they have good "sales" reasons to drop 1914 but on the other hand they can't directly do it because of the temple-inspection scenario.
To add to this confusion, I just want to mention that I believe his "parousia" and his "epiphania" (coming in great glory, glory seen by all) are 2 different things. I think his parousia starts with genuine spirit-baptized ("annointed") persons on earth. It started somewhere at the beginning of the 20th century when Christ annointed persons from heaven to become part of his wife-to-be. By annointing people to be his wife, he was again present in the flesh (through the flesh of his wife). Husband and wife being one flesh, ya, know *g*
He will be present(parousia) as long as genuine members of his wife's body are around on earth. And (then?) he will "arrive in his glory" (epiphania) so that every eye will see him. The scripture do not say "every heart will see him"! They clearly tell us that he will return on the clouds just as he went away.
But that are just my 2 coins...
