This is the somewhat arcane question which has been raised on the b-trans e-mail list, and is also related to my post on Hebrews 2:14 at Better Bibles Blog and to Lingamish’s response to that post.
The discussion started when I objected to a proposed rendering “mortal humanity” in Hebrews 2:14, to replace or refer back to the literal “flesh and blood”. My issue was that “flesh and blood” refers to humanity in general, not just to mortal humanity but also to the resurrection bodies which Jesus has and which we will have. But I was surprised that my suggestion proved so controversial. Here I hope to show that Jesus’ resurrection body has blood, and that this is important for our salvation.
