Jesus Christ fundamentally changes human nature
“To be delivered from one socio-religious world to another is to undergo a change of nature. According to Paul the cross and resurrection transfigured human life, translating those who receive Christ from flesh to Spirit, from the nomos of condemnation to the justifying nomos of the Spirit, from the pedagogy of elementary things to the paideia of Christ. By the cross and resurrection, Jesus takes the two physeis of Jew and Gentile, mixes the elements and comes out with a new chemical combination: Christian physis, a spiritual community made up of those born by Spirit.”
