Through the resurrection of Christ

And behold, again it hath been spoken,
that there is a first resurrection,
a resurrection of all those who have been,
or who are, or who shall be, down to
the resurrection of Christ from the dead,
the reuniting of the soul with the body,
of those from the days of Adam
down to the resurrection of Christ.

In other words,
their resurrection cometh to pass
before the resurrection of
those who die after the resurrection of Christ.

The souls and the bodies are reunited,
of the righteous, at the resurrection of Christ,
and his ascension into heaven.
