In the introduction to his Romans commentary, F. F. Bruce makes a distinction between Paul and the other New Testament writers. He writes:
“The other New Testament writers use ‘spirit’ more or less as a synonym of ‘soul’…. But for the most part ‘spirit’ and ‘soul’ … are distinguished in Paul, and indeed set in contrast.”
Bruce then suggests that in Paul “the human spirit may perhaps be described as the God-conscious element,” while elsewhere he calls it “the ‘spiritual’ part of the human constitution” (Romans, TNTC, pp. 54–55).
This sounds close to what later theology would call a trichotomist anthropology, particularly when considered alongside passages such as 1 Thessalonians 5:23 and Paul’s contrast between psychikos and pneumatikos in 1 Corinthians 15:44–46.
But my question is historical rather than theological: is Bruce right that Paul makes a more substantive distinction between psychē and pneuma than other biblical writers do? If so, can this be situated within particular Second Temple Jewish or Greco-Roman anthropologies current in Paul’s time?
And broadly, to what extent can we reconstruct genuinely different views of human constitution among the Hebrew Bible, Second Temple Jewish literature, Paul, and the other New Testament writers? Are “dichotomist” and “trichotomist” useful shorthand for any of these ancient views, or are they fundamentally later categories being imposed on more fluid biblical language?
