Acts and Romans

The canonical ordering of the NT does not carry the authority of the text itself, but it is not irrelevant. (Eugen Rosenstock-Huessy, among others, has shown that the canonical order of the gospels links them together into a unified literary unit.)

With this in mind, it is not irrelevant that Romans follows Acts. The narrative of Acts, especially its concluding chapters, sets up the theme of Romans. When we get to the end of Acts, the question on our minds is not “how can I find a gracious God?” but “what is God doing with Israel?” (I am not, however, suggesting that these are unrelated questions.)
