In The Unity of the Corinthian Correspondence, David Hall argues that 1 and 2 Corinthians are closely related. In both letters, Paul faces the same opponents, referring to them in the same disguised, indirect way in both 1 Corinthians and 2 Corinthians 1-9 before confronting them directly in 2 Corinthians 10-13. Furthermore, many passages in 2 Corinthians echo the teaching of 1 Corinthians, while others refer to the Corinthian reaction to the first letter. Hall therefore maintains that modern attempts to regard 1 and 2 Corinthians as a mosaic of fragments are based on a flawed methodology that fails to appreciate Paul's pastoral teaching. This is volume 251 in the Journal for the Study of the New Testament Supplement series.
