This is the second Memorial™ that I have been to since waking up. I paid extra attention to how they explained the two hopes. I tried to hear it like a person visiting for the first time would hear it. As you can see above, they used Revelation to show a number in heaven (they didn't read the scripture about the great crowd also being in heaven). Then to show the earthly hope, instead of reading a scripture that clearly states that everyone else lives on earth (because let's be honest there ain't one) they read the usual scriptures in Isaiah of a nice sounding earth and said the fact that you desire these things is proof that you have an earthly hope.
Everything that you just said, except substitute "first Memorial" for "second Memorial". I was trying to imagine how logical the explanation of two hopes would sound to a new one, and, well, it didn't. Considering how they glossed over the subject, I think the important point for them was just to explain to all of us why we shouldn't do anything with the emblems that were about to be passed to us except pass them right on. "You're not in this elite group, so no wine and crackers for you." It's like the Soup Nazi, but with holy emblems of Christianity.
