Load of church silver, holy books missing (6)
I believe the answer is:
Here is my best explanation:
'load' is the definition.
('charge' can be a synonym of 'load')
'church silver holy books missing' is the subsidiary indication.
'church' becomes 'ch' (common abbreviation).
'silver' becomes 'argent' ('argent' can be a synonym of 'silver').
'holy books' becomes 'nt' (New Testament).
'missing' indicates named letters should be taken away.
'argent' with 'nt' taken out is 'arge'.
'of' is the link.
(Other definitions for charge that I've seen before include "running cost", "Deliver an official injunction", "Attack - cost", "Explosive", "Lord Cardigan's order to his brigade", "impeachment", "Sortie", "Accusation (in court)", "Storm" and "Care".)
