Second Corinthians is a rather difficult book to outline because it is a very personal letter.
"Traditionally, Paul's two letters to Timothy and one to Titus are called the Pastorals.' But 2 Corinthians has a strong claim to be recognized as the Pastoral Epistle par excellence, because it contains not pure' but applied' pastoralia."63
Paul's purpose in writing was not to teach doctrine primarily, though he did so to a considerable extent. It was primarily to answer the criticisms of opponents who were seeking to undermine his ministry, especially in Corinth.
"Here it is his strong feeling rather than any deliberate arrangement that suggests the order of his utterances. Nevertheless, although exact analysis is seldom possible owing to digressions and repetitions, yet some divisions are fairly clear, and the letter becomes more intelligible when they are noted."64
