Romans 6:6f. The old self (anthropos) is our archetypal Adamic self, rooted in Eden’s curse. Old implies a New … a New Self. Paul is saying that the humanity that defined you before coming to faith in Christ is dead, that old Adamic self was destroyed in Christ on the cross only to birth a new humanity, no longer defined by Adam but by Christ.
The old Adamic self is the self you once were, the self that belongs to the old aeon (this present, evil age), the self dominated by sin and exposed to wrath (Fitzmyer, p. 436).
The “old anthropos” is not a part of the “new” self, but the old self ruled by sin, and dead in trespasses and sin (Eph. 2). That self was co-crucified with Christ … the only explicit reference to the cross in Romans.
As we consider ourselves as “Co-crucified” our inner being is drawn into the mystery of mysteries … the sacrificial death of Christ, the Lamb of God who takes away the sin of the world.
So there’s an identity that died along with Christ. Why? That the body of sin might be destroyed (v. 6). For the purpose of liberating us from the enslavement of sin.
What on earth is the “body of sin”? Some translations say, sinful body, as if the physical body as such were sinful. It is Paul’s shorthand for the whole person defined by sin, controlled by it, the old self … enslaved under the domain of sin and death (“the body of death” in Rom 7:24). By being co-crucified with Christ this sinful self is “destroyed” so as to liberate from enslavement.
What is Sin? There’s lots of misunderstanding about the nature of sin.
Sin is a diabolical power, trampling down and bringing death to every living species. Its power is demonstrated in all attempts to demythologize it, sterilize it, ignore or dismiss it. And those who acknowledge it often misdiagnose it as a wrong that one DOES (known as sins) rather than a reality that WRONGS the doer and the deed alike (Leander Keck, Romans, p. 185).
So how are we to respond. What has taken place in Christ must be actualized, appropriated.
11Consider yourselves dead to sin and alive to God in Christ Jesus (11)
12Let not sin therefore reign in your mortal body, to make you obey its passions (lusts, cravings).
Mortal body – v. 12 – the physical body, still mortal and yet to be glorified … it remains corruptible and prone to desires, some of which are harmful, from the domain of sin. The Christian life, says the writer to the Hebrews 12:4 … is a struggle against sin … remaining in union with Christ is the means of overcoming it.
Paul is not suggesting some form of sin management; sin refuses to be managed, that’s why Christ put it to death.
Yet we are living in-between this present, evil age and the age to come. Until one participates in Christ’s resurrection (future), the body is still subject to the inevitability of death and vulnerable to the power of its passions / desires. What matters for Paul is whether passions, the lusts of the flesh, control the self.
Like one being trained to recognize counterfeit currency, only studying authentic bills, Paul, likewise calls us to fix our eyes on Jesus, the author and perfecter of our faith, the icon of the Father.
He’s calling us to communion. He’s calling us to re-member Him, to participate in his death, resurrection and ascension.
Paul in addressing the sordid past of the Christians at Corinth, in I Cor. 6, mentions a list of sins ranging from sexual to gluttony and affirms their transformation in the lines … 11 And such were some of you. But you were washed, you were sanctified, you were justified in the name of the Lord Jesus Christ and by the Spirit of our God.
There’s no sin management here, but a complete emphasis on the sacramental grace received in baptism – washed, sanctified, justified in the name of the Lord Jesus and by the Spirit of our God. They no longer identify with their former lives defined by addictions, orientations, and the like.
