Right. Because the Bible says store up your treasure on earth. Oh wait....
The fact is, it would be theft to sell off Christian sanctuaries and artistic treasures which are part of the patrimony of the whole Church, for liquid cash to pay for temporalities, pensions for Cardinals and such.
It would be taking away what *belongs* to the poor and to all future generations, and illicitly converting it for private or temporary advantage.
I imagine you know the meaning of the terms "embezzlement" and "violation of fiduciary trust."
The Bible pretty clearly says to give God the best you have. That's why the accoutrements in the temple were covered in gold.
