I love the last line of the Apostles’ Creed:
[. . . I believe] in the resurrection of the body and the life everlasting. Amen.
While the Creed may not have the same level of authority as inspired Scripture, it nevertheless represents the best of the collective wisdom of early Christians.
And they described our eternal hope as “the resurrection of the body and the life everlasting.”
Interestingly, they did not describe it as “the immortality of the soul.”
One of my most significant learnings of recent years is the discovery that Christianity is much more about the resurrection of the body than it is about the immortality of the soul.
Check especially I Corinthians 15. The whole chapter. You’ll see that life after life after death was a more pressing concern for Paul than merely life after death.
It’s in the Creed. It’s in Scripture. It’s in the way the ancient mind worked.
