The relationship between 1 Corinthians 1 - 4 and the pursuant chapters has been a perennial issue for scholars of 1 Corinthians. Recent scholarship stressing the rhetorical unity of 1 Corinthians has demonstrated that the entire letter may well be read as an homonoia speech. Precisely how so in 1 Corinthians 5 remains a matter of some confusion. This is no more clear than in scholarship focused on inner-biblical exegesis, which has strongly emphasized the role of Jewish Scripture in Paul's ethical argumentation. These scholars tend to see an end to Paul's rhetorical-philosophical argument and the beginning of Pauline sexual ethics grounded in Jewish Scripture. My aim is to demonstrate Paul's thoroughgoing homonoia argument in 1 Corinthians 5. Assailing the Corinthian Strong wit5h a barrage of rhetorical and philosophical arguments, Paul simultaneously exposes the false wisdom of the Strong and espouses his own social ethic for the protection and preservation of the Corinthians' social body.
