Henry abandons anguished unorthodox Christian figure (5,3)
I believe the answer is:
agnus dei
'christian figure' is the definition.
(name for Jesus Christ)
'henry abandons anguished unorthodox' is the wordplay.
'henry' becomes 'H' (symbol for the unit of electrical inductance).
'abandons' suggests deleting specific letters.
'unorthodox' indicates an anagram.
'anguished' with 'h' removed is 'anguised'.
'anguised' is an anagram of 'AGNUS DEI'.
(Other definitions for agnus dei that I've seen before include "religious piece" , "Christian emblem" , "sacrificial offering" , "Part of Latin Mass" , "'Latin mass prayer, Lamb of God (5,3)'" .)
