2 Corinthians 6:14 to 7:1, An Interpolation

Interpolation - The material is seen by commentators as different. So some think it is not original but stuck in. Why?

For: - Interrupts presentation of Paul's inner feelings which resumes in 7:2
- Modified from another letter has own theme
- Eight terms only ever used here in Paul's letters
- harsh tone of the text

Against: - Material is just a digression
- Paul himself is modifying quotes from others to make his points
- Quotation from Old Testament is normal for Paul
- Tone needed to break through the mindsets of those wanting to join non-believers
- Section matches overall theme of the Corinthians' reconciliation with both Christ and Paul
- Following verses ease the tone of the previous criticism.
