text: The Codex Boernerianus lacks the explicit references to the Roman church as the audience of the epistle found in Romans 1:7 and 1:15. There is evidence from patristic commentaries indicating that Boernarianus is not unique in this regard; many early, no longer extant manuscripts also lacked an explicit Roman addressee in chapter 1. It is notable that, when this textual variant is combined with the omission of chapters 15 and 16, there is no longer any clear reference to the Roman church throughout the entire epistle. Harry Gamble speculates that 1:7, 1:15, and chapters 15 and 16 may have been removed by a scribe in order to make the epistle more suitable for a "general" audience.
  Fifteen-chapter form
  It is quite possible that a fifteen-chapter form of Romans, omitting chapter 16, may have existed at an early date. Several scholars have argued, largely on the basis of internal evidence, that Chapter 16 represents a separate letter of Paul – possibly 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, whereas the material of chapters 1–15 presupposes that Paul has never met anyone from the Roman church. The fact that Papyrus 46 places Paul's doxology at the end of chapter 15 can also be interpreted as evidence for the existence of a fifteen-chapter recension of the epistle.
