The warm introduction to the epistle (1:1-9) led Paul to give a strong exhortation to unity. In it he expressed his reaction to reports of serious problems in this church that had reached his ears.
"Because Paul primarily, and in seriatim fashion, addresses behavioralissues, it is easy to miss the intensely theologicalnature of 1 Corinthians. Here Paul's understanding of the gospel and its ethical demands--his theology, if you will--is getting its full workout.
". . . the central issue in 1 Corinthians is salvation in Christ as that manifests itself in the behavior of those "who are being saved."This is what the Corinthians' misguided spirituality is effectively destroying.
"Thus three phenomena must be reckoned with in attempting a theology of this Letter: (1) Behavioral issues ( = ethical concerns) predominate. . . . (2) Even though Paul is clearly after behavioral change, his greater concern is with the theological distortions that have allowed, or perhaps even promoted, their behavior. This alone accounts for the unusual nature of so much of the argumentation. . . . (3) In every case but two (11:2-16; chaps. 12-14), Paul's basic theological appeal for right behavior is the work of Christ in their behalf."18
The remainder of the body of this epistle deals with questions the Corinthians had put to Paul in a letter. Paul introduced each of these with the phrase peri de("now concerning,"7:1, 25; 8:1; 12:1; 16:1, 12).
"Rather than a friendly exchange, in which the new believers in Corinth are asking spiritual advice of their mentor in the Lord, their letter was probably a response to Paul's Previous Letter mentioned in 5:9, in which they were taking exception to his position on point after point. In light of their own theology of spirit, with heavy emphasis on wisdom' and knowledge,' they have answered Paul with a kind of Why can't we?' attitude, in which they are looking for his response."160
The Apostle Paul concluded this epistle with a series of imperatives, exhortations, and news items.
