5:1 It is actually reported that sexual immorality exists among you, the kind of immorality that is not permitted even among the Gentiles, so that someone is cohabiting with 1 his father’s wife.
1 tn Or “someone has married”; Grk “someone has,” but the verb ἔχω (ecw) is routinely used of marital relationships (cf. BDAG 420 s.v. 2.a), including sexual relationships. The exact nature of the relationship is uncertain in this case; it is not clear, for example, whether the man had actually married the woman or was merely cohabiting with her.
2 tn Grk “both this [stomach] and these [foods].”
sn There is debate as to the extent of the Corinthian slogan which Paul quotes here. Some argue that the slogan is only the first sentence – “Food is for the stomach and the stomach is for food” – with the second statement forming Paul’s rejoinder, while others argue that the slogan contains both sentences (as in the translation above). The argument which favors the latter is the tight conceptual and grammatical parallelism which occurs if Paul’s response begins with “The body is not for sexual immorality” and then continues through the end of v. 14.
