Organised Church welcomes support raised for Rapture (8)
I believe the answer is:
radiance
'welcomes support raised for rapture' is the definition.
I can't tell whether this defines the answer.
'organised church' is the wordplay.
'organised' becomes 'radian' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'church' becomes 'ce' (abbreviation for Church of England).
'radian'+'ce'='RADIANCE'
Can you help me to learn more?
(Other definitions for radiance that I've seen before include "Glowing quality" , "moonlight" , "shine" , "Brightness" , "Luminous state" .)
