Theologian Thomas (7)
I believe the answer is:
aquinas
'theologian thomas' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for aquinas that I've seen before include "Sainted theologian" , "St. Thomas --, theologian" , "Old theologian" , "'dumb ox'" , "Saintly theologian" .)
