Love having dispute about vessel (7)
I believe the answer is:
worship
'love' is the definition.
(worship is a kind of love)
'dispute about vessel' is the wordplay.
'dispute' becomes 'row' (row is a kind of dispute).
'about' says the letters should be written backwards.
'vessel' becomes 'ship' (ship is a kind of vessel).
'row' written backwards gives 'wor'.
'wor'+'ship'='WORSHIP'
'having' is the link.
(Other definitions for worship that I've seen before include "Idolise" , "Adoration of a divine being" , "Love" , "Honour" , "what can priest offer?" .)
