There is strong indirect evidence that a copy of Romans that lacked chapters 15 and 16 was widely used in the western half of the Roman Empire until the mid-4th century. This conclusion is partially based on the fact that a variety of Church Fathers, such as Origen and Tertullian, refer to a fourteen-chapter edition of Romans, either directly or indirectly. The fact that Paul’s doxology is placed in different places in various manuscripts of Romans only strengthens the case for an early fourteen-chapter copy. While there is some uncertainty, the canonical sixteen-chapter recension is likely the earlier version of the text. It is quite possible that a fifteen-chapter form of Romans, omitting chapter 16, may have existed at an early date. Some have argued that chapter 16 represents a separate letter of Paul, maybe addressed to Ephesus, that was later appended to Romans. There are a few different arguments for this conclusion. First of all, there is a concluding peace benediction at 15:33, which reads like the other Pauline benedictions that conclude their respective letters. Secondly, Paul greets a large number of people and families in chapter 16, in a way that suggests he was already familiar with them. On the other hand, the material of chapters 1-15 presupposes that Paul had never met anyone from the Roman church. How do you end your letters?
