Church officer in charge gets cross (6)
I believe the answer is:
celtic
'cross' is the definition.
(Celtic cross is an example)
'church officer in charge' is the wordplay.
'church' becomes 'CE' (Church of England).
'officer' becomes 'lt' (abbreviation for lieutenant).
'in charge' becomes 'ic' (abbreviation for 'in charge').
'ce'+'lt'+'ic'='CELTIC'
'gets' is the link.
(Other definitions for celtic that I've seen before include "Group of languages including Irish, Welsh, etc" , "Gaels, for instance" , "Scottish club" , "Racial of Welsh, Irish etc." , "Like, eg, Welsh, Gaelic" .)
