Yes. No First Adam, no Second.

That said, there are still certain dynamics of the Catholic conception of the moral order that still resonate (with me). Humans are clearly both capable of appalling evil and a longing to be delivered from it, thereby appealing to a transcendent moral authority. The amazing thing about the Christ story is that it interpreted a failed prophet as a divine savior, upending the conception of power as dominance. The gospel is vigorously anti-exploitation and anti-dominance (and anti-suffering: in the kingdom, all would be fed). In that sense the gospel is divine, since humans are basically animals with big brains hard-wired for dominance and violent conflict.
