1 Corinthian and 2 Corinthians give us several snapshots of the development of the Corinthian church and Paul's relationship to it. In 1 Corinthians Paul is concerned with controversies that have been dividing the church, most probably along social status lines. The issues causing controversy include whether one should eat food sacrificed to idols, how one ought to conduct oneself sexually, the practice of speaking in tongues, and how Christians will be resurrected from the dead. 2 Corinthians shows that these issues seem to have been resolved. However, 2 Corinthians 10-13 (probably a separate letter) presents Paul in a defensive posture, struggling to justify his position over and against the new "super apostles" that have infiltrated the Corinthian church.
