Sounds like the "theology" he learned from Macial was fundraising.  M. was extraordinary as one.  Seems a reason the Vatican turned a blind eye to his other deviations.  Any cleric who produces fund raising skills will be promoted pronto! Now it seems to be emerging why his star has been constantly on the rise.
Did Farrell's brother leave the order?  Does he also have a  Vatican post?  Seems Farrell may have left order not because of M. Did he ever publicly state his reason for leaving as Marcial's madness? 
Priests often leave orders for secular clergy as there is a better career path more directly in going secular.  That's why it took so long to get a Jesuit pope because of their prohibits against promotion.
I thought Wilton Gregory of Atlanta gave same reason why he needed a palatial home?
He backtracked when it was publicly revealed.  Evidently, F. had no resistance in Dallas?
