The next pressing issue Paul addresses after concluding his exhortation on the
relationship between the congregation and their leaders and influences is one of blatant immorality exceeding
the sexual misconduct of the unbelievers. There were reports of incest tolerated among members of the
Corinthian church. Recent lectures from our church family camp featured themes like the abiding validity of
God's law. Our passage today adds another reference to reinforce this thesis. Here in Paul's exhortation,
applications from Leviticus 18 are in view. The sacred bonds and boundaries of marital covenant are to be
maintained among the people. Even unbelievers affirm this so some degree, and in this case, the social norms
of the pagans only strengthened the witness against the corruption in the Corinthian church.
