In his chapter on homosexuality in The Moral Vision of the New Testament Richard Hays argues that in Romans 1:
Paul is offering a diagnosis of the disordered human condition: he adduces the fact of widespread homosexual behaviour as evidence that human beings are indeed in rebellion against their Creator. The fundamental human sin is the refusal to honor God and give God thanks (1:21); consequently, God’s wrath takes the form of letting human idolatry run its own self-destructive course. Homosexual activity, then, is not a provocation of ‘the wrath of God’ (Rom 1.18); rather, it is a consequence of God’s decision to ‘give up’ rebellious creatures to follow their own futile thinking and desires. The unrighteous behavior catalogued in Romans 1:26-31 is a list of symptoms: the underlying sickness of humanity as a whole, Jews and Greeks alike, is that they have turned away from God and fallen under the power of sin. (387)
Now, doesn’t that definition of “humanity” as “Jews and Greeks alike” strike you as odd? If Paul is offering a “diagnosis of the disordered human condition” or, as Ian Paul puts it in the Grove booklet on Same-Sex Unions, “telling the cosmic history of the failure of humanity” (24), why does Paul speak specifically of the coming wrath against the Greek (Rom. 2:9)?
