J. C. O'Neill is already well known for his strikingly original studies of various books of the New Testament, and his latest work, a commentary on Romans, is no exception. It is immediately obvious that this is a commentary with a difference, a commentary which argues a thesis, viz., ‘that the words of the epistle handed down to us were not written by one man, were not written at one time, were not written to one audience’. On the contrary, he suggests, Paul's original letter has been subjected to two sorts of corruption, each of which has added new material to the text. First, glosses have been copied into the text by mistake in later years. Second, interpolations have been added by later editors, usually from old traditions, in order to supplement the epistle and make it more suitable for general use (p. 14). Some of the interpolations which O'Neill claims to identify are of considerable length. For example, 10.16–11.32 is attributed in its entirety to a theologian of the second century. Indeed, out of chapters 9–14, containing 148 verses in the form of the letter that we know, O'Neill assigns only twenty-one verses to Paul.
