Final considerations

The authorial unity of Luke and Acts is little argued in scholarly circles, since virtually everyone unanimously agrees the external and internal evidence confirm single authorship. That the external evidence is from the latter part of the second century and beyond or that the internal evidence tends to favor similarities over differences does not receive much attention.

The current project was undertaken to re-examine the evidence for the authorial unity of Luke and Acts by analyzing their seams and summaries in light of ancient prose composition criticism and modern stylometric methods. The statement to be tested may be expressed thus: If the common authorship of Luke and Acts is true, their seams and summaries, genre-neutral text, will reveal the same or similar prose compositional features. If differences of a statistically significant or highly significant nature are discovered, single authorship may, or better, must, be called into question. Given this, a three-stage analysis evolved as the most appropriate methodological approach.
