A member of a Roman Catholic religious order founded by Ignatius Loyola in 1534 (6)

I believe the answer is:

jesuit

(Other definitions for jesuit that I've seen before include "One in a Catholic order" , "Catholic priest" , "member of a religious order" , "Member of RC order" , "Member of the order founded by St Ignatius Loyola and St Francis Xavier" .)

I've seen this clue in The Independent.
