Story provided by Catholic and Anglican organisation (7)
I believe the answer is:
romance
'story' is the definition.
(romance is a kind of story)
'catholic and anglican organisation' is the wordplay.
'catholic' becomes 'roman' (Roman Catholic is an example).
'and' means one lot of letters go next to another.
'anglican organisation' becomes 'ce' (I can't justify this - if you can you should give a lot more credence to this answer).
'roman'+'ce'='ROMANCE'
'provided by' acts as a link.
Can you help me to learn more?
(Other definitions for romance that I've seen before include "marriage?" , "Feeling of mystery; love affair" , "Make up stories - Menorca (anag)" , "fairy story?" , "Language group; love affair" .)
