Drinking beers, company and church come together (8)
I believe the answer is:
Here is my best explanation:
'come together' is the definition.
'drinking beers company and church' is the wordplay.
'drinking' is an insertion indicator.
'beers' becomes 'ales' (I've seen this before).
'company' becomes 'co' (abbreviation).
'and' is a charade indicator (letters next to each other).
'church' becomes 'ce' (abbreviation for Church of England).
'ales' put within 'coce' is 'COALESCE'.
(Other definitions for coalesce that I've seen before include "Unite", "To bring together", "Grow together, amalgamate", "Merge into one", "Combine and form one whole, as political parties may", "Combine with others as political parties may do", "Fuse or cause to grow together", "Come together in one mass", "Amalgamate" and "come together".)
