Article on building - your start to divine rule (8)
I believe the answer is:
thearchy
'divine rule' is the definition.
'article on building your start' is the wordplay.
'article' becomes 'the' (the definite article).
'on' means one lot of letters go next to another (in a down clue, letters appear on others).
'building' becomes 'arch' ().
'start' indicates taking the first letters.
The initial letter of 'your' is 'y'.
'the'+'arch'+'y'='THEARCHY'
'to' is the link.
(Other definitions for thearchy that I've seen before include "rulership" , "Ecclesiastical governors" , "Rule by god(s)" , "religious form of ruling" .)
