Come together, finding a form of solace in church (8)
I believe the answer is:
Here is my best explanation:
'come together' is the definition.
(I've seen this before)
'a form of solace in church' is the subsidiary indication.
'a form of' indicates anagramming the letters (the letters need to be in another \'form\').
'in' means one lot of letters goes inside another.
'church' becomes 'ce' (abbreviation for Church of England).
'solace' with letters rearranged gives 'oalesc'.
'oalesc' inserted inside 'ce' is 'coalesce'.
'finding' is the link.
(Other definitions for coalesce that I've seen before include "Merge into one", "Combine with others as political parties may do", "Grow together, amalgamate", "'Fuse, combine (8)'", "Fuse or cause to grow together", "Come together in one mass", "Run together", "Make one whole", "Join into one mass" and "Amalgamate".)
