Mosiah 15:21

And there cometh a resurrection, even a first resurrection; yea, even a resurrection of those that have been, and which are, and which shall be, even until the rssurrection of Christ: for so shall he be called.

There will be a resurrection. It’s called the first resurrection. People who have lived, are living now, and will live until Christ comes back will be in it. Christ is what he will be called.

A resurrection is coming—the first resurrection. It includes everyone who lived and died before Christ’s own resurrection. That’s what we’ll call it—Christ’s resurrection.
