An Evangelist's stigmata, perhaps (5)
I believe the answer is:
marks
'an evangelist's stigmata' is the definition.
'marks' can be an answer for 'stigmata' ('mark' can be a synonym of 'stigma'). I'm not sure about the 'an evangelist's' bit.
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for marks that I've seen before include "Stains" , "Former German currency" , "Grades assigned to school work" , "Visible signs" , "Goals" .)
