ISB ~ 2 Corinthians 2 v14 - 7

Paul makes a long digression to explain the significance of his apostolic ministry. He resumes the story of Titus’ mission and return in 7:5. Some take this digression as evidence that a separate letter has been incorporated into the text; however, there is no evidence for such an insertion in the surviving manuscripts of 2 Cor, and digressions are common enough in ancient letters to suffice as an explanation for the momentary shift in subject matter.
