There is Only One Humanity

For as in Adam all die, so in Christ all will be made alive. (1 Corinthians 15:22)

There is only one human nature, one humanity, of which we all partake. The Incarnation, God becoming man and dwelling among us (John 1:14), was not about creating a new and different humanity — that would have been a species alien to us — but it was Christ partaking of the one and only humanity there is. It means that Christ participates with us in our humanity, even as broken as it is, so to make us whole.

So, the cross saves us in a very ontological way. That is, Christ did not die as one whose humanity was similar to but quite other than our humanity, dying instead of us in a different humanity, and somehow creating a legal fiction to satisfy a legal debt. There is no real connection in that between Christ and humanity.

No, Christ died as one with whom we participate together in the same humanity, dying as us, so that his death was our death, too, because his being shares in our being, in our nature as human beings. His death was our death, so that his risen life is ours, as well. This cannot be reduced to some sentimental way of thinking; is the objective reality of our own being participating together in the resurrected human being of Christ.

In the same way, we are righteous before God, not because of some legal accounting (imputed righteousness), or by receiving it from a source outside of us (imparted righteousness), but through Christ’s very real participation in human being, our mutual participation with Christ in the only humanity there ever was or shall be. This one and only humanity, which was once headed up in Adam is now headed up in Christ, which is why the apostle Paul can make the Adam/Christ comparison so extensively, in Romans 5 and 1 Corinthians 15.

Consequently, just as one trespass [Adam’s] resulted in condemnation for all people, so also one righteous act [Christ’s] resulted in justification and life for all people. (Romans 5:18)

The Byzantine icon of the Resurrection, above, shows Christ, with the shattered gates of hell^* beneath his feet, reaching his hands to Adam and Eve, and raising them from the grave. “For as in Adam all die, so in Christ all will be made alive” (1 Corinthians 15:22).
