Faithfulness, devotion (7)
I believe the answer is:
loyalty
I believe this clue is a double definition.
'faithfulness' is the first definition.
(I know that loyalty is a type of faithfulness)
'devotion' is the second definition.
(I've seen this in another clue)
(Other definitions for loyalty that I've seen before include "Firmness of allegiance" , "Faithfulness" , "Firm allegiance" , "Faithfully allegiance" , "Fidelity, allegiance" .)
