This is short and quick but maybe it's a seed to plant in the 10 days until the Memorial. I have talked to JWs who tell me their reason for not eating the bread and drinking the cup is because that was only a New Covenant with His disciples (and in their wonky extension, the 144,000). But I just thought of a few things.
First off, that's not even true because in John 6:53-54, Jesus was talking to more than His disciples. But let's assume that's true: why are they doing other things Jesus only told His disciples about? Like the preaching work. The flimsy proof texts given for the need to preach for salvation were only spoken to the disciples: Matthew 24:14 (see verse 3, He told the disciples these things "privately"); Matthew 28:19-20. In two accounts (starting Matthew 10:1 and Mark 6:7), Jesus tells them to pair off and preach; only Luke 10 talks about the 70 (or 72) disciples but just say "well, the 12 is equal to the 144,000, why aren't they equal to the 70? The accounts are otherwise the same." The fact remains, in the most-cited reasons for the "preaching work" (in Matthew), Jesus was talking directly to His nearest and dearest disciples. If the Lord's Supper is only for His disciples who will rule with Christ in heaven, why should anyone but that anointed group preach? Or: why are they disciples for the preaching work, but not for the very act that symbolizes that they're a part of the New Covenant?
